Adtran launches FSP 3000 open line systems for the coherent optical edge

Adtran launched its FSP 3000 Edge OLS, an open line system designed for the new generation of coherent edge access, aggregation and metro networks. The platform is specifically engineered for the use of coherent transmission at the optical edge, including the recently introduced Coherent 100ZR, as well as 400ZR optics. 

Adtran says that by utilizing power-optimized wavelength broadcasting technology and a gridless architecture, its solution enables a simple and affordable optical layer with compact and flexible nodes that can transport any coherent signal and baud rate. 

The modular OLS supports multiple use cases, including linear, hub-and-spoke or tree topologies. The platform delivers single-degree functions in 1RU (add/drop, line amplification, OTDR, OSC). It features a carrier-grade and hardened design for outdoor deployments, enabling operation in extended temperatures range (-40°C to 65°C).

“At OFC, we showcased our world-first QSFP28 Coherent 100ZR, bringing robust, efficient and simple coherent technology to the edge of the network. Now we’re complementing this innovative transceiver with an OLS optimized for the cost-efficient transport of coherent technology at the optical edge. Providing maximum performance, it meets all critical demands of edge aggregation networks, including scalability, compact design, low power consumption, operational simplicity and extended temperature operation for outdoor deployment,” said Christoph Glingener, CTO at Adtran. “Our pioneering work at the network edge is creating whole new opportunities for service providers.”

“Our FSP 3000 Edge OLS offers a major boost to operators looking for an affordable way to tackle relentless growth in data traffic. Low-cost yet highly flexible, it can scale to transparently accommodate any line speed or baud rate. Now there’s a clear route to deploying an optical layer that leverages coherent transport technology, including 100ZR and 400ZR optics, and meets the stringent requirements of the new optical edge,” commented Henning Hinderthür, VP of product line management, Optical Networks at Adtran. “Our FSP 3000 Edge OLS harnesses advanced wavelength broadcast technology for new levels of power and cost efficiency. It’s also ready to be deployed anywhere from central offices to street furniture.

WSJ: Tipster in Ericsson's bribery case awarded $279 million by SEC

The tipster who reported Ericsson to the U.S. Securities and Exchange Commission for bribery was awared $279 million under the government's cash-for-tips program, according to The Wall Street Journal. A tipster can be awarded between 10% to 30% of fines collected, depending on circumstances.

Ericsson resolved the case with the SEC in 2019, agreeing to pay a $1.1 billion fine. A subsequent issue led to Ericsson being fined an additional $207 million.

The identity of the tipster has not been disclosed.

Broadband Forum issues TR-459 Issue 2 spec

The Broadband Forum announced the second issue of Technical Report-459: Multi-Service Disaggregated BNG with CUPS.

"TR-459 Issue 2 includes an additional layer of flexibility to manage subscriber resiliency, simplifying operations and streamlining provisioning and maintenance," said Jonathan Newton, Co-Director of the Access and Transport Architecture Work Area at Broadband Forum from Vodafone.

Any faults that can cause network outages can be navigated around as the new specification enables the brain of the network (known as the Control Plane, responsible for managing interactions with the customer home router) to intelligently determine whether a switchover to a new User Plane is needed. The User Plane carries network traffic and enforces policies such as Quality of Service (QoS).

“The latest release of the TR-459 standard will continue to drive standards-based interoperability between vendors, with Broadband Forum simplifying network transformation and ensuring more agility and flexibility for broadband operators,” said Craig Thomas, Vice President Strategic Marketing and Business Development at Broadband Forum. “Our work on a Multi-Service Disaggregated Broadband Network Gateway (DBNG) continues to make it easier to deliver fixed broadband services quickly to new and existing customers as the industry continues to transition and offers a migration path from legacy infrastructures to a future agile cloud native approach.”

Standardization of the Control and User Plane Separation (CUPS) for a Multi-Service DBNG enables the Control Plane from one vendor to control and manage the User Plane from another vendor. This builds a more diverse supply chain with a greater choice of Control and User Planes from different vendors leveraging the TR-459 standard.

Broadband Forum members showcased the important capabilities enabled by TR-459 Issue 2 as part of the CloudCO Demonstration at Network X 2022. The demo highlighted Subscriber Group Resiliency and switchover, and DBNG-User Plane traffic steering. The network monitored the subscriber traffic SLAs and when the SLAs were not being met, switched the subscribers to the backup DBNG-User Plane. Subscriber Group Resiliency minimizes network outages during any network faults.

MaxLinear supplies PAM4 DSP for JPC's 800G active electrical cable

Taiwan-based JPC Connectivity has selected MaxLinear’s 5nm Keystone PAM4 DSP to produce 800G active electrical cables for hyperscale datacenters. 

JPC Connectivity will demonstrate the new cables at Computex 2023 in Taipei, Taiwan from May 30 – June 2.

MaxLinear said its Keystone can yield up to a 40% power saving over competitor solutions. The Keystone 5nm DSP family has been designed to address both 400G and 800G applications and is the first generation to provide 106.25Gbps host side electrical I/O to match the line side 106.25Gbps interface rate. Variants supporting single mode optics (EML and SiPh), multimode optics (VCSEL transceivers and AOCs), and Active Electrical Cables (AECs) are all available and can be paired with companion TIAs to provide complete solutions.

“We’re excited to partner with JPC Connectivity on these new active optical cables,” said Drew Guckenberger, Vice President of High Speed Interconnect at MaxLinear. “Our Keystone DSPs offer a significant power advantage in this type of application, which is increasingly becoming a critical factor with hyperscale data centers.”

“Our new 800G cables using the low power, high performance Keystone DSP is designed to meet the market’s need for next-gen interconnect solutions as datacenters transition from passive DAC cables,” said Jessica Chang CEO at JPC Connectivity. “We are happy to have MaxLinear as a partner for this innovative new product.”

Marvell posts revenue of $1.322 billion, seems AI as a growth driver

 Marvell Technology reported revenu of $1.322 billion for the first quarter of its fiscal year 2024, $22 million above the midpoint of the company's prior guidance and down 9% year-on-year. GAAP net loss for the first quarter of fiscal 2024 was $(168.9) million, or $(0.20) per diluted share. Non-GAAP net income for the first quarter of fiscal 2024 was $264 million, or $0.31 per diluted share. Cash flow from operations for the first quarter was $208.4 million.

"We delivered first quarter fiscal 2024 revenue of $1.322 billion, above the midpoint of guidance, and are forecasting sequential revenue growth in the second quarter. We are expecting revenue growth to accelerate in the second half of this fiscal year, accompanied by gross and operating margin expansion," said Matt Murphy, Marvell's President and CEO. "AI has emerged as a key growth driver for Marvell, which we are enabling with our leading network connectivity products and emerging cloud optimized silicon platform. While we are still in the early stages of our AI ramp, we are forecasting our AI revenue in fiscal 2024 to at least double from the prior year and continue to grow rapidly in the coming years."
