Huawei announces 50G PON prototype

Huawei announced a single-wavelength 50G passive optical network (PON) prototype.

The new unit provides 50 Gbps downstream transmission rates and 25 Gbps/50 Gbps upstream transmission rates over a single wavelength.

Huawei's design is based on mature 25G optical components. It achieves 50 Gbps transmission rates over a single wavelength through fiber dispersion compensation and transmitter/receiver bandwidth compensation technologies on the physical PON links. Under the 1:64 split ratio, the prototype supports transmissions over 20 km, and enables customers to smoothly transition to 50G PON networks without needing to change the ODN of the live network. The prototype is also fully compatible with XG(S)-PON and 10G-EPON in the 50G PON wavelength planning. To protect operators' investment, 50G PON boards are designed so that they can be inserted and run in the Huawei new-generation smart distributed OLT MA5800.

In February 2018, the ITU-T officially initiated the 50G PON standards project and began developing technical solutions and standards. The standards are expected to be finalized in 2020 and put into commercial use in 2023.

Huawei notes that is a contributing member of the ITU-T and IEEE in 50G PON technology.

Intel intros 10G PON chipset for FTTx and 5G base stations

Intel introduced a new multimode 10G PON chipset designed for small form-factor pluggable optical network termination (SFP+ ONU) and single family unit (SFU) ONUs.

In a blog post, Intel's Dirk Wieberneit writes that SFP+ ONU plays a crucial role in fiber deployments by providing entire ONU (Mac and PHY) connectivity between the 10G PON optical network and any unit it is plugged into, such as residential gateways, MDUs, DPUs, mobile small cells and base-station equipment. This positions the new chipset for a wide range of implementations in both residential and business environments, including SFU, SFP+ ONU, fiber to the distribution point (FTTdp)/multi-dwelling unit (MDU), and 5G base stations, while enabling service providers to reuse their existing fiber infrastructure.

A key feature is an embedded 2.5 Gigabit Ethernet (GbE) PHY, which supports low-power, cost-effective SFUs, providing fast speeds both into and throughout the home.

Other features of the chipset:

  • It can be used in both ITU and IEEE PON environments (EPON, 10G-EPON, GPON, XGPON1, XGS-PON, NG-PON2 and active optical Ethernet.)  
  • It is prepared for bidirectional optical subassemblies (BOSA), allowing cost-effective BOSA on board (BoB) ONU designs. 
  • It supports network timing synchronization protocols, such as IEEE 1588v2, synchronous Ethernet or time of day (ToD), providing clock accuracy for 5G/LTE mobile base stations.
  • It offers embedded VoIP supporting FXS voice ports. 
  • It delivers the necessary quality of service (QoS) and power management, carrier-grade features and hardware OAM, including Y1731, with the highest accuracy.  
  • It includes a dual-core, multithread processor and dedicated packet processing engine so you get both service application flexibility and benchmark performance.

Google's Super PON could be a game changer

Google is working on a "Super PON" architecture that could improve the economics of fiber-to-the-home deployments, said Claudio DeSanti, Architect at Google Fiber, speaking last week at ADTRAN's Broadband Business Solutions event in Huntsville, Alabama.

Google's foray into last mile fiber access networks dates back to 2010 when it announced plans to challenge the incumbent telcos and MSOs in the U.S. with a Google-branded and delivered gigabit broadband and TV service. Google Access picked Kansas City for its first deployment and opened a public comment process to identify future rollout locations. Nearly 1,100 communities across the country expressed interest in participating in the Google project and nearly 200,000 individuals submitted comments.

DeSanti presented the timeline that eventually took Google Access to 11 cities

Then, in October 2016, the Google Fiber project officially hit the pause button. Craig Barratt, who was CEO of Access, stepped down. The said it would continue rolling out in the cities in it was already present, but that is was pausing operations and laying off workers in many cities where it had once anticipated deploying an FTTH network. Google said its effort had spurred AT&T and others to get serious about FTTH, while holding out the possibility of reentering the market if and when new technology options became available.


De Santi said the major lessons learned from this undertaking were that building infrastructure is complex, especially the lengthy permitting process that varies from city to city, and that last mile construction and outside plant costs represent the bulk of spending, mostly because of labor. Google found aerial FTTH to be prohibitively expensive due to policy restrictions of pole sharing with utility companies.

Regarding future rollouts, DeSanti said Google is now taking a more practical perspective on running the business for profit and sustainability.

In February 2018, Dinesh (Dinni) Jain ws been appointed CEO of Access, the new name for the Google Fiber and Webpass business. Jain most recently served as Chief Operating Officer of Time Warner Cable.

DeSanti said the Super-PON architecture that his team is developing could be a game changer for several reasons. First, it targets a 50 km reach from the Central Office to the subscriber, rather than the 20km target of the current technology. The longer reach is achieved with amplification. This means a larger serving area per CO, and few COs needed to cover a whole city. For a mid-sized U.S. metropolitan area, the current PON architecture requires Google to operate 16 COs. The Super PON might need as few as 3 COs to do the same job. These CO could also be CDN distribution points. No active equipment is deployed outside the CO. It operates over a passive ODN.

Second, the Super PON targets up to 1,024 subscribers, up significantly from the maximum 64-subscriber split available on its current technology. With Super PON, DWDM is used to multiplex multiple channels over a single feeder fiber. DeSanti said few fibers would be needed to support the same number of customers, enabling the deployment of small cables (12-48 fiber cables versus 432-fiber cables). The advantage of smaller cables is that micro-trenching techniques can be used, cutting the time and cost of deployment. Repairs to a fiber cut could also be handled much faster for a 24-fiber cable (under 2 hours) versus 8-hours to repair a 432-fiber cable.

DeSanti noted that Super PON standardization began in January 2018 with a presentation at the New Ethernet Applications group of IEEE 802.3. Last month, IEEE 802.3 approved the formation of a Super PON Study Group. In parallel, Super PON has also been presented to both ITU-T and FSAN, possibly as an NG-PON2 extension. Google has a pre-standard implementation deployed in the field.

An open question is whether Super PON economics leads Google to unpause its Access ambitions.

Dell'Oro forecasts fast growth for next-gen PON technologies

The worldwide PON market will grow to over $7 billion by 2022, according to a newly published report by Dell’Oro Group, driven by next-generation PON technologies, including 10 Gbps EPON, XGS-PON, and NG-PON2. This represents a compounded annual growth rate of almost 40 percent from 2017 to 2022.

“Where PON technologies are used for residential broadband services, 2.5 Gbps GPON will remain as the dominant technology due to its lower price and sufficient speeds.  However, for a number of growing use cases such as business services and mobile backhaul, next-generation PON technologies have capacities and capabilities that current generation technologies lack,” said Alam Tamboli, Senior Analyst at Dell’Oro Group.

“10 Gbps EPON has already begun shipping strongly in China where current generation PON is widely deployed.  Shipments of XGS-PON and NG-PON2 remain small for now, but we anticipate that XGS-PON will grow more rapidly. XGS-PON and its 10 Gbps symmetric bandwidth should meet operators’ needs for business services and mobile backhaul,” Tamboli added.

AT&T completes software-based XGS-PON field trials

AT&T completed field trials of a 10 Gbps XGS-PON virtualized network using Open Source Access Manager Hardware Abstraction (OSAM-HA) software in Atlanta and Dallas.

OSAM-HA, which was previously known as Virtual Optical Line Termination Hardware Abstraction (VOLTHA), enables a virtualized Broadband Network Gateway (BNG) function to manage subscribers. OSAM is a vendor agnostic operational suite for managing consumer and business broadband access network elements and capabilities; separate from vendor-specific Access Element Management Systems (EMS).

XGS-PON is a fixed wavelength symmetrical 10Gbps passive optic network technology.  During the trials, the XGS-PON system tested multi-gigabit high-speed Internet traffic and provided a seamless AT&T DIRECTV NOW video experience to participants.

One observation from the trial is that AT&T found it possible for GPON and XGS wavelengths to coexist across a single fiber interface.

“Our network is constantly evolving. We’ll continue to execute our software-based network strategy to technologies like 5G, virtualized RAN, and G.FAST over time. Ultimately, instead of deploying islands of technology that have SDN control, we want to orchestrate the entire end-to-end network through ONAP,” said Eddy Barker, assistant vice president, Access Architecture and Design, AT&T.

ONAP stands for Open Network Automation Platform. It’s our virtual access project within the Linux Foundation and will use the first iteration of OSAM-HA technology.

AT&T releases its Virtual Optical Line Termination Hardware Abstraction to ONF

AT&T is contributing its Virtual Optical Line Termination Hardware Abstraction (VOLTHA) code into the Open Networking Foundation (ONF).

VOLTA provides the framework behind AT&T's XGS-PON access network in the cloud. AT&T is currently performing proof-of-concept testing of VOLTHA in its labs and are planning to deploy XGS-PON field trials before the end of 2017.

AT&T described its decision to contribute its VOLTHA code as one more step in its commitment to move toward open source software and SDN/NFV frameworks.

Nokia combines PON with integrated wireless drop

Nokia introduced a "wireless PON solution" that allows operators to bring gigabit services to customers using WiGig wireless technology, eliminating the need to bring fiber all the way to a home or building.

Nokia's Wireless PON integrates Passive Optical Network (PON) technology with WiGig, a high-speed, 60 GHz standard otherwise known as 802.11ad. It can be mounted to telephone poles, street lights or a building facade and uses beamforming to bring connections of up to 1Gbps to Nokia WPON home units located up to 300 meters away on the outside of a building or home. The solution has the ability to connect multiple access points in a row. Network operators might also use the wireless PON or create a WiGig meshed network in a neighborhood.

Federico Guillén, president of Nokia's Fixed Networks Business Group, said: "Multi-technology strategies are key to helping operators quickly roll out new ultra-broadband services to more people. Leveraging advancements made in today's wireless technologies, we're demonstrating how operators can use a wireless drop alternative to effectively deliver fiber-like speeds to customers. Nokia's new Wireless PON solution will introduce FTTx options that operators can use to enhance the way customers experience their broadband services. With a strong portfolio across all FTTx technologies including fiber, DSL, cable and wireless, Nokia has the experience it takes to deliver these multi-technology broadband networks and make the business case work."

Nokia Bell Labs demos ultra low latency 10G PON for fronthaul

Nokia has announced that as part of its work to better support mobile fronthaul and latency-sensitive services, Nokia Bell Labs has demonstrated a commercial next generation PON (NG-PON) transporting ultra-low latency CPRI streams over a single fibre connecting the baseband unit (BBU) and remote radio head (RRH).

The proof of concept demonstration was conducted in accordance with the latency budget requirements for the fronthaul of commercial radio equipment, showing that existing fibre networks can be used to transport mobile traffic and help accelerate the roll-out 5G.

Nokia noted that fronthaul comprises a key element of the C-RAN (centralised RAN) architecture in mobile networks, where the processing power is centralised away from cell sites. This model helps operators reduce the cost and power consumption of on-site installations, as well as simplifying cell cooperation schemes that help enhance network capacity and coverage.

In a C-RAN architecture, the legacy common public radio interfaces (CPRI) and certain next generation fronthaul interfaces require ultra-low latency transport, often in the sub-millisecond range, to meet the timing and synchronisation requirements of 4G and 5G technologies.

In the latest demonstration, Nokia Bell Labs validated that next generation PON technology, XGS-PON (10 Gbit/s symmetrical PON), can meet the strict timing constraints and deliver the capacity required, while also reducing the cost of mobile cell site transport. XGS-PON runs over existing fibre access networks and allows operators to use GPON platforms and technology to deliver high capacity services.

Nokia stated that this is a key capability for operators as they seek to address the challenge of supporting 'anyhaul' applications. By removing the need for a separate network, operators can use existing PON infrastructure in FTTH/B deployments to cost-effectively achieve the performance and coverage they require to handle the mobile transport demands resulting from densifying cell sites.

Nokia added that in addition to mobile transport applications, PONs are increasingly seen as an attractive option by operators seeking to support latency sensitive services and IoT applications such as manufacturing control and connected vehicles.

Nokia Bell Labs latest technology breakthrough will help mobile service providers as they move towards implementing 5G, and expands Nokia's Anyhaul mobile transport solutions as well as strengthening its portfolio of converged access networks for the delivery of fixed and mobile services. The company claims that to date it is involved in nine trials or commercial deployments of XGS-PON.

Huawei notes call for industry convergence to support next generation PON

Huawei announced that during the first PON industry development workshop held recently in Beijing, a consensus was reached to propose a PON industry development forum to the Broadband Forum (BBF) to support coordination and collaboration among PON standards development organisations including ITU-T/FSAN, IEEE and BBF and thereby enhance industry convergence.

Huawei noted that due to the cost sensitivity of the PON industry, which primarily addresses home broadband access, it was proposed during the workshop that the deployment of next generation PON systems enabling 10 Gbit/s and higher bandwidth will need to take into consideration the external ecosystem spanning transport, Ethernet and data centre networks, Additionally, next generation PON will need to reuse the cost-effective optical/electrical components and technologies deployed commercially at scale.

In addition, it was proposed that to help expand the PON ecosystem, the community should take measures relating to areas such as PON industry development coordination, standard requirement and roadmap management and standardisation coordination and cooperation. Finally, the workshop participants agreed to host future workshops as necessary to enable discussion regarding key technical issues in PON industry development.

Huawei noted that PON is currently the mainstream access technology used by operators for FTTH ultra-broadband deployments. To date, two competing standards have been adopted, the IEEE's EPON/10 Gbit/s EPON and ITU-T GPON/XG(S)-PON, leading to duplication in types of system and related equipment installed in operators' networks, resulting in higher network construction and maintenance costs.

In order to promote a converged PON ecosystem, a group of standards development organisations (SDO) has jointly issued a statement on PON convergence, To help expand PON market scale, share industry chain resources and reduce deployment costs and time to market (TTM), and thereby create a sustainable PON ecosystem, the operator and vendor representatives at the workshop called for the convergence of standards for next generation PON.


The recent workshop in Beijing was attended by representatives from standard organisations such as the Broadband Forum (BBF) and Institute of Communication Standards Research (ICSR), operators including China Telecom, China Mobile and China Unicom, and system and optical module vendors including Huawei, Nokia Shanghai Bell, Accelink, FiberHome, Hisense, Source Photonics and ZTE.

Alcatel-Lucent Intros 10G TWDM-PON

Alcatel-Lucent is looking to bring down the cost of TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Networks) by allowing different types of optics to be used.  Currently, TWDM-PON requires new optics capable of providing four tunable 10 Gbps wavelengths.

Alcatel-Lucent's new ‘Universal TWDM’ solution enables operators to initially deploy one non-tunable 10 Gbps wavelength and easily add more pluggable as demand grows, providing a smooth upgrade to full TWDM without the need to replace network components, evaluate new technology, or reconfigure operations and business support systems (OSS/BSS).

"The primary obstacle for deploying new ultra-broadband infrastructure and services is the business case. Universal TWDM is Alcatel-Lucent’s innovative solution to this challenge. We are enabling operators to build upon their existing fiber investments while bringing down the total cost of ownership of TWDM technology. This means they can immediately address new high-revenue opportunities for gigabit services while knowing that their investment is future-proof,” stated Federico Guillén, president of Alcatel-Lucent’s Fixed Access Business Line.

The company noted that Universal TWDM and full TWDM-PON can co-exist with current PON technology. Alcaltel-Lucent also estimates that Universal TWDM will have a similar cost as established 10 Gbps technologies, such as XG-PON.

IEEE Study Suggests Multiple NG-EPON Specs

The IEEE released a Feasibility Assessment for the Next Generation of EPON based on the input of the wide industry ecosystem, including operators, system integrators, chip vendors, optics suppliers and others. Input was collected on the desired features and options for a next generation of EPON, operating at aggregate data rates above 10 Gigabit per second and minimizing the footprint and power consumption in optical access networks.

To address the diversity of market requirements, the referenced communication suggests consideration of multiple NG-EPON solutions, including a multi-wavelength 40G solution with an evolutionary path to 100G and single-wavelength solutions supporting the data rates of 25G symmetric or 25G downstream/10G upstream.

“The new PHYs need to consider the coexistence with the deployed EPON technologies and reuse functions and components of 10G-EPON to the extent possible,” states the IEEE 802.3 communication.

Said Marek Hajduczenia, chair of the IEEE 802.3 Industry Connections NG-EPON Ad Hoc and network architect with Bright House Networks: “The IEEE 802.3 Industry Connections NG-EPON Ad Hoc was launched to explore the market potential and technology options for an NG-EPON operating at data rates beyond 10G. The expectation is that information contained within the published communication will help with development of a future Call for Interest for NG-EPON and, afterwards, a new standard within the IEEE 802.3 Ethernet Working Group.”

ADTRAN Cuts Costs of NG-PON2 Architecture Using Flexible Transceivers

ADTRAN is adopting a flexible optics approach to significantly cut the cost of delivering Fiber-to-the-Premise (FTTP) services based on NG-PON2 architecture.

The company said its breakthrough uses the latest 10G wavelength symmetric ITU/FSAN standards-based technology. ADTRAN's system can interoperate with multiple “cost vs. capability” types of optical transceivers to maximize economic flexibility. The company claims this “pay as you grow” approach allows the service provider to align the optics cost with the target applications, starting with low-cost symmetric 10G deployment options and growing to multi-wavelength TWDM capabilities.

ADTRAN’s NG-PON2 platform supports 10 Gigabit GPON, TWDM PON, P2P DWDM, 10 Gigabit EPON, and GPON. To optimize the full service agility promise of NG-PON2, ADTRAN’s solution supports provisioning through modern, open APIs, facilitating deployment using next-generation software defined networking (SDN)-based management systems. The company says its new architecture is currently available for demonstration and will begin field trials in the third quarter of this year.

“ADTRAN has a long history in developing designs that break economic barriers, giving service providers the maximum flexibility they need to deliver the services of tomorrow that their customers demand today,” said Robert Conger, associate vice president, carrier strategy for ADTRAN. “With seemingly infinite demand for broadband from both residential and business customers, service providers are challenged to explore economically viable options that allow them to scale PON networks to support Gigabit service growth.”

This means they can immediately address new high-revenue opportunities for gigabit services while knowing that their investment is future-proof,” stated Federico Guillén, president of Alcatel-Lucent’s Fixed Access Business Line.

The company noted that Universal TWDM and full TWDM-PON can co-exist with current PON technology. Alcaltel-Lucent also estimates that Universal TWDM will have a similar cost as established 10 Gbps technologies, such as XG-PON.

  • In October 2014, Alcatel-Lucent introduced the industry’s first TWDM-PON (Time and Wavelength Division Multiplexed Passive Optical Networks), a new fixed, ultra-broadband access technology for scaling the capacity of existing fiber networks. TWDM-PON uses four wavelengths per fiber, giving a total capacity of 40 Gbps. An operator can choose to deliver different services over each wavelength, enabling residential, business and mobile backhaul services to be carried over a single fiber. TWDM-PON technology is supported by Alcatel-Lucent‘s 7360 Intelligent Services Access Manager FX solution.  The company is introducing a new 4-port TWDM-PON line card and optical network unit supporting 10Gbps symmetrical bitrate. Products will be available in the first quarter of 2015.  Alcatel-Lucent and Vodafone have been co-developing TWDM-PON since 2010 as a potential successor to GPON. During this time, the companies have contributed to its standardization and completed a successful trial. Significantly, TWDM-PON can co-exist with current PON systems.

Huawei Unveils Smart Optical Line Terminal

Huawei introduced a "smart: optical line terminal (OLT) with distributed architecture for next generation passive optical networks (NG-PON).

The SmartAX MA5800 is designed for the rapid creation of new network services as fixed broadband increasingly shifts from home access to multi-service access (e.g. enterprise access and Wi-Fi hotspot backhaul), and from simple bandwidth-rental operations to flexible user experience operations.

It leverages a distributed architecture to provide non-blocking access for high-density 10G-PON, 40G-PON, 100G-PON, and WDM-PON. Both the PON and P2P ports on the MA5800 support fixed mobile convergence (FMC) access including home access, enterprise access, mobile backhaul, and Wi-Fi hotspot backhaul. It also supports WDM-PON, which can be used to provide multiple symmetrical P2P channels over one fiber line and features high quality of service (QoS) and high service security.

Huawei also noted SDN-based smart service capability , which enables centralized management on massive ONUs of various types to achieve high O&M efficiency and low OPEX.

"Huawei endeavors to improve the end user's experience and build an intelligent access network with faster broadband, wider coverage, and smarter connection," said Jeff Wang, President of Huawei’s Access Network Product Line. He added, "The new OLT launched by Huawei, the MA5800, supports the FMC service, provides an optimized smart service experience, and unlocks the potential of ultra-broadband enabling carriers to gain an advantage over their competitors."
