Semtech debuts XGSPON chipset

Semtech announced production availability of itsGN7153B combo chip and GN7055B multi-rate burst mode transimpedance amplifier (TIA) for XGSPON Optical Line Terminals (OLTs).

Semtech's GN7153B is a combo chip supporting OLT transmit and receive signals in a fully integrated solution.

On the receive side, the GN7153B supports both XGPON (2.5G) and XGSPON (2.5G/10G) signals, while the transmit data path features Semtech’s 10G EML driver with ClearEdge CDR technology to effectively reset the signal jitter budget. Transmit path optimization can be accomplished through an I2C programmable PLL loop bandwidth control and a variety of jitter filter modes. The EML driver includes eye-shaping features and an Automatic Power Control (APC) loop to deliver best-in-class transmit eye quality. The burst mode receive data path includes a multi-rate 2.5G/10G limiting amplifier with a fast burst mode signal detect function, integrated discharge circuit and reset for short settling time.

Semtech said its high sensitivity burst mode TIA (GN7055B) is designed for XGSPON OLT applications. Using an external reset signal, the burst mode TIA meets the convergence time and burst dynamic range requirements of XGSPON 2.5G and 10G.The device features a fast Automatic Gain Control (AGC) loop to enable high dynamic range in burst mode applications. The GN7055B is offered in die form, supports industrial temperature range and uses a single 3.3V power supply.

“XGSPON will bring a new generation of faster optical broadband services for home and business to the largest sector of the PON market,” said Dr. Timothy Vang, Vice President of Marketing and Applications for Semtech’s Signal Integrity Products Group. “Our chipset contributes to that growth by bringing high performance and low cost.”

Champion ONE intros XGS-PON Optical Transceivers

Champion ONE announced commercial availability of a new line of XGS-PON transceivers for delivering symmetrical 10G service in fiber-to-the-premises (FTTx) networks.

This product line conforms to the ITU standards G.987.2 and G.9807.2. It includes both SFP+ and XFP transceivers for OLT applications, and SFP+ transceivers for ONU applications over 20km rated distances.

Champion ONE notes that XGS-PON deployments will enable telecom network operators to converge services over a common fiber infrastructure, with legacy 1G GPON service and new 10G XGS-PON service over the same fiber.

“Network operators are deploying deeper fiber, copper/coax optimization, and next-generation radio access upgrades to support growing bandwidth demand among end-users,” said Champion ONE CEO John Jutila. “Our network architecture workshops with telecom infrastructure operators highlighted XGS-PON as one of several planned access technology upgrades. We are proud to be an integral partner with our customers to enhance their networks with this new application in our expanding portfolio of open port solutions.”

Champion One is based in Cleveland, Ohio.

Frontier picks Nokia XGS-PON to deliver 10G business and residential services

Frontier Communications will deploy Nokia's XGS-PON technology to deliver faster broadband speeds to business and residential customers. The phased roll out of the new enhanced services will initially focus on the greater Dallas/Fort Worth areas of Texas before expanding to the rest of the state along with Florida and California. 

Specifically, Frontier is extending its Nokia 7360 deployment with next-generation PON line cards. These allow Frontier to deploy XGS-PON or TWDM-PON on the same card with a pluggable optic swap.

Nokia's Next generation PON supports both traditional and SDAN (Software Defined Access Network) approach. The temperature-hardened 7360 supports 100G network uplinks/rings in CO and many cabinet based deployment options.

Steve Gable, CTO and EVP at Frontier Communications, said: "We are excited to be working with Nokia on solutions that bring multi-Gigabit services to the home and quickly scale to 10 Gigabits and beyond. Nokia's platform will enable us to effectively support xDSL, P2P fiber, GPON and 10Gbps PON requirements and gain the flexibility to seamlessly evolve into future PON technologies. Nokia's solutions will enhance the customer experience by offering a Frontier fiber-powered internet that is as fast as it is reliable."

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.

Telefónica Hits 10Gbps with Nokia's XGS-PON FTTH

Telefónica has successfully tested Nokia's XGS-PON next-generation fiber-to-the-home (FTTH) technology in its labs, delivering symmetrical broadband speeds of up to 10Gbps. The technology is expected to facilitate Telefonica's 5G mobile network roll-out.

Nokia said its XGS-PON will provide a simple upgrade path from the current GPON fiber technology deployed by Telefonica.

The companies noted that the XGS-PON lab trial showed four times more upstream bandwidth than XG-PON.

Federico Guillen, president of Nokia's Fixed Networks business group, said: "Streaming services, gaming and HD video continue to drive demand for gigabit services, and the use of next-generation fiber technologies like XGS-PON will play a critical role in Telefonica's ability to deliver these enhanced services to customers - by wireless or fixed networks. The enhancements to our next-generation PON portfolio make it easier and more cost-effective for service providers to seamlessly evolve their existing fiber networks in line with demand."
