Acacia debuts single-carrier 1.2 Tbps pluggable powered by new DSP

Acacia, which is now part of Cisco, introduced the first, single-carrier 1.2 terabits per second (1.2T) faceplate pluggable coherent module powered by its "Jannu" 5nm CMOS digital signal processor (DSP) ASIC. 

The new 1.2 Tbps pluggable, which represents the 8th generation of Acacia's coherent module family, combines the Jannu DSP with 3D Siliconization packaging technology, including the silicon photonics integrated circuit (SiPh PIC), high-speed modulator driver and transimpedance amplifier (TIA) in a single opto-electronic package.

“Today is an exciting new milestone in Acacia’s history as we once again introduce an exciting new product that delivers the type of disruption needed to cost-effectively scale network capacity in the future,” said Mehrdad Givehchi, Sr. Director of Engineering for Hardware and Software and Founder at Acacia. “With every generation of product, we have been able to deliver higher transmission data rates, lower power consumption and higher performance and I am proud to see this new product carry on that legacy.”

Acacia notes that its new Coherent Interconnect Module 8 (CIM 8) can address transmission of multiple 400GbE client interfaces, delivering 1.2T per carrier capacity for high-capacity DCI interfaces and 800G per carrier capacity over most optical links using 4 bits/symbol (~16QAM) modulation.

The Jannu DSP features Acacia’s second-generation 3D Shaping technology, which leverages enhanced probabilistic constellation shaping (PCS) algorithms and Adaptive Baud Rate. This provides continuous baud rate adjustment up to 140Gbaud to optimize utilization of available spectrum in a single-span or in cascaded ROADM paths. The Jannu DSP also includes Acacia’s advanced line-rate processing algorithms to efficiently overcome fiber transmission impairments over greenfield or brownfield fiber infrastructures. These power-efficient algorithms are designed to compensate linear and non-linear impairments, as well as provide state-of-polarization (SOP) tracking with industry leading response times. In addition, the Jannu DSP leverages Acacia’s new soft-decision error correction (SD-FEC) to further enhance performance.

Nokia launches its FP5 network processing silicon

Nokia unveiled its fifth-generation FP5 IP routing silicon capable of powering 800GE routing interfaces in service provider networks. Nokia promises a 75% reduction in power consumption and new embedded line rate, flow-based encryption capabilities.  FP5-based platforms will be available starting in the first half of 2022.

Nokia's FP5 is a fully programmable network processor (NPU) for Nokia’s IP service routing platforms. The company says the FP5 is the first ASIC on the market to deliver up to 48 ports of QSFP-DD 800 without further hardware or fabric upgrades. Some highlights:

Security: With the current generation FP4 silicon, Nokia transformed volumetric DDoS defense with router-based detection and mitigation. With FP5, Nokia brings an additional layer of network protection with the introduction of ‘ANYsec’ - a new line rate, flow-based encryption capability integrated directly into the chipset. ANYsec supports the delivery of secure IP services including MPLS and segment routing, on-demand and at scale without impacting performance or power efficiency. Service providers can now ensure the integrity and confidentiality of all data flowing through their networks.

Network Capacity. Nokia service router platforms are the first to support high-density 800GE and 1.6 Tbps clear channel routing interfaces for applications including mobile transport, IP core, peering, BNG and provider edge. New FP5-based line cards will support 14.4 Tbps (19.2 Tbps with Nokia’s intelligent aggregation capability.) A new series of fixed form factor 7750 Service Router-1 platforms enable the benefits of FP5 to also be realized in smaller network locations.

Energy Efficiency: Nokia’s FP5 network processors drive down power consumption per bit by 75%. As FP5 is backwards compatible with FP4 and fully integrated into the latest versions of Nokia’s Service Router Operating System (SR OS), all existing features are supported from day one on the new hardware. 

Some specs:

  • 4.8 Tbps
  • delivered with a 2.5D system-in-package (SiP) construct
  • First NPU to support 100G SERDES
  • Largest device in the industry using line rate memories everywhere, for both buffering and tables, in a completely deterministic configuration
  • First NPU with embedded line-rate network encryption for L2, L2.5 and L3
  • First to support multiple 1.6 Tbps clear channel flows
  • Support for 400G ZR/ZR+, 800G and 1.6 Tbps speeds
  • External MAC ASIC with QoS pre-processing, pre-classification, pre-buffering and first level DDoS protection and encryption

Federico Guillén, President of Network Infrastructure, Nokia, said: “Of all the things that are surprising about human beings, perhaps the most surprising is our ability to be surprised. Our customers require their networks to be robust, agile and adaptable enough to handle everything life throws at them – from disruptive security threats to a global pandemic. FP5 is a significant step forward in performance, security and efficiency and – in combination with our software excellence and investment in network automation and tools – it opens the next chapter in Nokia’s long-standing leadership in IP networking and IP silicon innovation.”

Neil McRae, Managing Director and Chief Architect, BT, said: “BT has a long-standing relationship with Nokia, and we are pleased to see that with FP5, Nokia continues to innovate to ensure IP networks have the scale, flexibility and features to help us stay ahead of escalating demand from our residential, mobile and business customers. In particular, we are very happy to see the focus on power optimization as we grow our network, with both BT and Nokia committing to significant reduction in carbon footprint. In the past 18 months, our lives have been turned upside down, and our reliance on networks has been dramatically increased and reliability for customers is crucially important. With security being ever more important for our customers, seeing Nokia’s approach to building more security features into the platform is fantastic.”

Holland's SURF research net evaluates ECI's 1.2Tbps optical transport blade

SURF, the Dutch National Research and Education Network, is testing ECI's Apollo TM1200 1.2T dual channel, programmable blade.

The trial runs over a 1650km link connecting SURF’s main facility in Amsterdam with CERN’s communication center in Geneva.

ECI said the trial demonstrated Apollo’s ability to support live traffic of 300 Gbps per wavelength over predominantly old (G.655) fibers, traversing 22 intermediate nodes without any signal regeneration or RAMAN amplification. Link capacity was increased by roughly 150% by optimizing line-rate modulation.

SURF’s optical backbone, SURFnet 8, was upgraded a couple of years ago to address the astonishing rate of growth in the demand for bandwidth. The search for a new vendor encompassed nine candidates, from which ECI was selected. Based on the Apollo family, SURF continues rebuilding its optical backbone for the future, achieving super-high performance, economic scalability, ease of operations, and a seamless migration from the previous infrastructure. The latter exemplifies an Open Line System (OLS) by carrying both ECI and alien lambdas.

“The TM1200 adds yet another layer of flexibility and programmability to our optical capabilities. With the TM1200 we can now optimize modulation schemes in line with our requirements and the distances transmitted, ensuring optimal use of our fiber capacity,” said Rob Smets, Network Architect at SURF. “We were pleased to discover we could improve link capacity and efficiency by approximately 150% just by replacing the card, even on our ‘old’ (G.655) fibers. With ECI’s help and our continuously updated network capabilities, we will continue to provide our millions of users with the levels of performance and service to which they’ve become accustomed.”

“We understand that today’s operators are under pressure to squeeze the most out of their network infrastructures. Optical backbones will forever be required to support, and exceed, simple low cost per bit transport,” said Christian Erbe, VP Sales EMEA at ECI. “However, there are increasing requirements for openness, programmability and interworking with the packet layer. ECI has a very strong relationship with national research and education networks (NREN) worldwide, and we are proud of our long-lasting partnership with SURF.”

ECI intros 1.2T Dual Channel Blade for its Apollo DWDM transport

ECI introduced its TM1200, a 1.2T blade (dual 600G channel) for its Apollo DWDM transport systems, enabling programmable, adaptive optical networking.

ECI said its new TM1200 blade delivers unmatched spectral efficiency and elasticity through software controllable continuous modulation. Whereas traditional line-side modulation was only programmable in large increments – such as 100G, 200G or 400G – often relying on different line cards, the new TM1200 delivers software-controlled continuous modulation in 50 Gbps increments up to 600 Gbps line rate, rather than supporting specific modulation schemes. This maximizes capacity in a granular manner to best match client needs and variable channel conditions.

Additional benefits:

  • Optimal return on fiber investment: By operating at the edge of the Shannon limit, the TM1200 squeezes the maximum capacity from each channel on a fiber, delaying the need to add new fiber and optical networking infrastructure.
  • Enables a highly adaptive and flexible optical layer: Working in conjunction with ECI's colorless, directionless, contentionless, flexible spectrum ROADMs, and client services aware SDN control, the TM1200 can continuously optimize client traffic to fiber capacity.
  • Dynamic restoration: Excess capacity can be allocated dynamically to fully or partially restore client services that are disrupted by fiber or equipment failures elsewhere in the network.
  • Power efficiency: At a 600 Gbps line rate, the ECI TM1200 has a 10-fold improvement in power efficiency compared to other solutions, consuming less than 0.18W per Gbps, fully populated.

Nokia completes single-carrier terabit-per-second field trial

Nokia announced the world’s first field trial of single-carrier terabit-per-second data transmission. The test was completed on Etisalat's network.

The trial successfully transmitted a record 50.8 terabits per second using multiple wavelengths, each with a net information rate of 1.3 terabits per second, over a 93-km fibre route of Etisalat’s wavelength division multiplexing (WDM) network.

The single optical carrier operated at 100 Gigabaud and employed Nokia Bell Labs-pioneered probabilistic constellation shaping, or PCS, to intelligently shape the signal to achieve maximum capacity for the specific fibre route. Nokia’s Photonic Service Engine 3 – now shipping to customers as part of Nokia’s 1830 portfolio – is the first coherent digital signal processor to implement PCS.

Nokia said the field trial demonstrates that Etisalat’s existing network can support the higher optical wavelength bit rates that will be required to support high-bandwidth services such as 5G extreme mobile broadband (very fast wireless to the mobile), fibre-to-the-home (FTTH) and Data Center Interconnect (DCI) cloud services. Higher bit rates per wavelength provide power and space savings, improved network simplicity, increased spectral efficiency and capacity, and ultimately reduced cost per bit compared to optical networks composed of lower rate channels.

Esmaeel Alhammadi, Senior Vice President, Network Development at Etisalat, said: "We are pleased to have partnered with Nokia Bell Labs to demonstrate that our optical network is capable of transporting a terabit per second over a single wavelength, and a total per-fibre capacity of over 50 terabits-per-second.  Increasing network capacity helps us to provide bandwidth-hungry services such as 5G extreme mobile broadband, fibre-to-the-home and DCI for enterprises.”

Sam Bucci, Head of Optical Networking at Nokia, said: “The introduction of 5G will require a network that can support dramatic increases in bandwidth in a dynamic fashion. This ground-breaking trial with Etisalat is testimony to Nokia’s commitment to continue to invest in coherent and optical component technologies required to meet the 5G networking challenge at the lowest total cost of ownership for our customers.”

Nokia Bell Labs, T-Labs and TU Munich Hit 1 Tbps w New Modulation

Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich have demonstrated a new modulation technique that achieved a net 1 Terabit per second transmission rate -  close to the theoretical maximum information transfer rate of that channel and thus approaching the Shannon Limit of the fiber link.

The trial, which was carried out as part of the Safe and Secure European Routing (SASER) project, used the optical fiber network of Deutsche Telekom. Bell Labs is calling the novel novel modulation approach "Probabilistic Constellation Shaping (PCS)."  It uses quadrature amplitude modulation (QAM) formats to achieve higher transmission capacity over a given channel to significantly improve the spectral efficiency of optical communications. PCS modifies the probability with which constellation points - the alphabet of the transmission - are used. Traditionally, all constellation points are used with the same frequency. PCS cleverly uses constellation points with high amplitude less frequently than those with lesser amplitude to transmit signals that, on average, are more resilient to noise and other impairments. This allows the transmission rate to be tailored to ideally fit the transmission channel, delivering up to 30 percent greater reach.

Marcus Weldon, president Nokia Bell Labs & Nokia CTO, said:  "Future optical networks not only need to support orders of magnitude higher capacity, but also the ability to dynamically adapt to channel conditions and traffic demand. Probabilistic Constellation Shaping offers great benefits to service providers and enterprises by enabling optical networks to operate closer to the Shannon Limit to support massive datacenter interconnectivity and provide the flexibility and performance required for modern networking in the digital era."

Mitsubishi Electric Develops 1Tbps Multi-subcarrier Optical Transceiver

Mitsubishi Electric Corporation has developed a multi-carrier optical transceiver capable of one Terabit per second (1 Tbps) rates -- a 10-fold improvement over current mainstream commercial transceivers, which operate at up to 100 Gbs) per optical receiver.

Mitsubishi Electric said it achieved the 1Tbps transmission rate with existing optical fibers by using a multi-subcarrier technology that transmits 11 light waves (subcarriers) simultaneously in a single channel by using an optical comb, a device that creates a series of discrete, synchronized optical waves equally and densely spaced in the channel. While conventional methods would require 11 receivers for the same number of subcarriers, this new technology only requires a single receiver due to the use of densely spaced, synchronized subcarriers in a single channel and novel multi-subcarrier signal processing algorithms. No major changes are required to the existing optical network infrastructure, keeping the cost of deploying this new technology quite low.

Usually, when using subcarriers for optical communication, each subcarrier undergoes different signal distortions, which results in damaged data like video distortion on the receiving end. To avoid this problem, Mitsubishi Electric used pilot signals to accurately realign the subcarriers at the receiver. Known pilot symbols are periodically inserted into the transmitted signal, which serves as a landmark for correct orientation of all subcarriers and prevents data damage.

The experiment also achieved a spectral efficiency of 9.2b/s/Hz, which as of January 2016, was the highest in the world in a 1Tbps transmission using a single optical receiver.

Bell Labs' MIMO-SDM Sets Path to Petabit/Sec Optical Transmission

Bell Labs, the research arm of Alcatel-Lucent, announced a space-division multiplexed optical multiple-input-multiple-output (MIMO-SDM) system with the potential to increase current 10 to 20 Terabit-per-second fiber capacities to Petabit-per-second capacity - the equivalent of 1,000 Terabits/s.

Bell Labs said it has demonstrated real-time 6x6 MIMO-SDM using six transmitters and six receivers in combination with real- time digital signal processing to remove cross-talk.  The experiment was conducted over a 60-km-long coupled-mode fiber in Bell Labs’ headquarters in New Jersey.

The researchers claim this MIMO-SDM technique could overcome the capacity limitations imposed by the non-linear ‘Shannon limit’ on current optical fiber.

“This experiment represents a major breakthrough in the development of future optical transport. We are at the crossroads of a huge change in communications networks, with the advent of 5G Wireless and cloud networking underway. Operators and enterprises alike will see their networks challenged by massive increases in traffic. At Bell Labs we are continuously innovating to shape the future of communications networks to meet those demands,” said Marcus Weldon, CTO of Alcatel-Lucent and President of Bell Labs.

Alcatel-Lucent announced the first commercially available single-carrier 100G technology in June 2010 and the first commercially available 100G/200G single-carrier line card in 2014, that can deliver up to 24 Tbps capacity.

In 2013, Alcatel-Lucent announced the first deployment of a 400G superchannel optical link with FT Orange with a capacity of 17.6 terabits-per-second, based on the 400G Photonic Service Engine (PSE), co-developed by Bell Labs.

Facebook Deploys Infinera for Multi-Terabit European Network

Facebook has deployed an Infinera Intelligent Transport Network  to light the world's longest terrestrial optical network route, spanning 3,998 kilometers without any regeneration.

The network, which is capable of delivering up to eight terabits per second (Tbps) of data transmission capacity, stretches from Facebook's data center in Lulea, Sweden across major hubs throughout Europe. Facebook deployed the Infinera portfolio of products, which includes the DTN-X platform, to connect these hubs, harnessing Infinera’s unique FlexCoherent solution to deliver terabits of capacity on a single fiber across the continent.

Infinera said its DTN-X platform enables Facebook's European network to deliver 100G coherent transmission via 500 Gbps super-channels, with the ability to support 1.2 Tbps super-channels in the future. The high capacity super-channels are enabled by 500 Gb/s photonic integrated circuits (PICs) developed and fabricated by Infinera – the only supplier providing 500 Gb/s of transmission capacity from a single line card. PICs enable the DTN-X platform to integrate wavelength division multiplexing super-channel transmission with up to 12 Tbps of non-blocking optical transport network switching, providing seamless scaling as traffic requirements grow in the future. The DTN-X also features SDN-ready application programming interfaces that enable network programmability and automation of network operations to reduce both operational cost and service delivery times while facilitating new services.

"The Infinera Intelligent Transport Network makes it easy for us to rapidly grow network capacity while keeping operations simple,” said Niclas Comstedt, Director of Network Engineering at Facebook. “Once the equipment is in place we are able to turn up as many terabits as we need."

“I’ve worked closely with service providers around the world to test and deploy ultra-long-haul optical transport systems for over a decade,” said Steve Grubb, Fellow at Infinera. “The route we are announcing with Facebook is delivering multi-terabit capacity today and I believe this is the world’s longest 8 Tb/s capable route in production.”

"Facebook's deployment of the Infinera Intelligent Transport Network underscores the value Infinera brings to Internet content providers and datacenter operators around the world," said Tom Fallon, Infinera CEO. "Facebook is a classic example of how leading Internet content providers are building global networks that interconnect their datacenters to accelerate the delivery of high bandwidth, feature rich services worldwide.”

PMC's DIGI-G4 Processor Scales OTN Line Card Capacity by 4X

PMC-Sierra has commenced sampling of its new DIGI-G4 chip -- the industry's highest density 4x100G OTN processor and featuring 50 percent less power per port than the previous generation.

The DIGI-G4 OTN processor, which builds on the success of PMC’s DIGI-120G, enabling the transition to 400G line cards in packet optical transport platforms (P-OTP), ROADM/WDM and optimized data center interconnect platforms for OTN switched metro networks. It increases 10G, 40G and 100G line card port density by 4X with flexible client mapping of Ethernet, storage, IP/MPLS and SONET/SDH, while reducing power by 50 percent per port. DIGI-G4 builds on the IP from DIGI-120G, enabling customers to maintain their rich feature set and software investment, which reduces time to market by up to six months and lowers development costs.

Significantly, DIGI-G4 delivers multi-rate, sub-180ns latency OTN encryption, allowing cloud and communications service providers to ensure security without compromising performance. DIGI-G4 supports sub-wavelength OTN encryption and is compatible with OTN switched networks. PMC said these these capabilities, combined with the densest 10G/40G/100G Ethernet ports, enables a new class of low-power, high-capacity transport platforms optimized specifically for the hyperscale data center WAN interconnect market (see whitepaper).

“Without DIGI-G4 the industry would be challenged to transition to 400G OTN switched metro networks,” said Babak Samimi, vice president of marketing and applications for PMC’s Communications Business Unit. “The world’s leading OEMs are designing around DIGI-G4 because our solution allows them to scale their product portfolios to the highest capacities at half the power per port, while leveraging their existing DIGI software investment. Coupled with new capabilities like OTN encryption, we’re solidifying PMC’s position as the industry leader in OTN processors.”

DIGI-G4 Highlights

  • Industry’s first single-chip 4x100G solution for OTN switched line cards
  • Integrated 100G Gearbox for direct connect to CFP2, CFP4 and QSFP28 transceivers
  • Industry’s highest density 10G, 40G and 100G multi-service support, including Ethernet, storage, IP/MPLS and SONET/SDH
  • Industry’s first sub-wavelength OTN encryption solution to secure the cloud
  • Industry’s first 25G granularity flexible framer to DSP interface providing scalable line-rates to match the programmable modulation capabilities found in next-generation Coherent DSPs
  • Multi-chip Interlaken interconnect solutions for scalable compact chassis data center interconnect applications
  • High performance OTN-SDK with adapter layer software accelerates customer time to market

The PM5990 DIGI-G4 is sampling now.
