Adtran's new FSP 3000 M-Flex800 offers ZR and ZR+ optics

Adtran launched its FSP 3000 M-Flex800 blade leveraging ZR and ZR+ optics for high-capacity transport solutions across edge, metro and core networks. 

The Adtran FSP 3000 M-Flex800 is a versatile, multi-rate line card able to support an extensive range of grey and coherent interfaces, including 100Gbit/s, 400Gbit/s, 800Gbit/s, ZR, ZR+, OpenROADM and other types of coherent optics. 

Compared to classical OTN muxponder solutions, the new, single-slot M-Flex800 card supports much simpler demarcation and multiplexing technology. It enables a new way to develop compact and low-power transport solutions from the edge to the core. This new IP-to-DWDM approach enables flexible, cost-efficient networking with separated IP and optical layers.

Some highlights

• Multiple chassis options, 1RU to 12RU, front/rear access, 300/600mm width, AC/DC 
• Stand-alone or with other terminals and optical line system components 
• Suitable for both new and existing deployments 
• Indoor or outdoor, with an ETSi-compliant, hardened 1RU chassis suitable for street cabinets

“Initially developed for DCI, ZR optics are now expanding their reach into diverse operational environments. Today’s launch will be key in that transition. Our new FSP 3000 M-Flex800™ will be a gateway between classical DWDM and the latest IPoDWDM, bringing the benefits of standardized ZR optics to a broad spectrum of operators,” said Christoph Glingener, CTO of Adtran. “Our versatile one-slot card acts as a universal host for ZR, ZR+ and OpenROADM coherent interfaces, seamlessly integrating into any open line system and enabling multiple use cases. Whether you’re looking to deploy in carrier infrastructure or DCI environments, in central offices or street cabinets, our M-Flex800™ can be easily slotted into any FSP 3000 chassis.”

Acacia intros 800ZR and 800G ZR+ coherent pluggables

Building on its success with 400ZR, Acacia’s introduced a portfolio of 800G DSP-based pluggable modules for metro data center interconnect (DCI) upgrades. Acacia’s 800ZR pluggables support QSFP-DD and OSFP form factors fully compliant to OIF 800ZR with transmit power variants.

• Acacia’s 800G ZR+ modules are designed to support the recently released OpenROADM specifications that include interoperable PCS transmission capability. 
• The 131Gbaud PCS provides additional OSNR margin at 800G for longer reach suitable for regional DCI applications, linking multiple fiber spans and in-line amplification between data centers. 
• Acacia 800G ZR+ pluggables support QSFP-DD and OSFP form factors with >1dBm transmit output power.

Acacia is also introducing a 400G QSFP-DD module for ultra long-haul applications. It offers 400G QPSK and PCS with various baud rates to fit into different ROADM optical line systems. It is capable of >1dBm transmit power and high transmit OSNR over the entire C-band thanks to the integrated tunable optical filter for amplified spontaneous emission reduction.

Both the 800G pluggable portfolio and 400G ultra long haul pluggable are powered by Delphi, Acacia’s 9th generation Digital Signal Processor (DSP) ASIC. 

Acacia notes that its 400G MSA coherent pluggable portfolio, based on its Greylock DSP, has now shipped more than 250,000 ports, including more than 10,000 Bright 400ZR+ ports.

The Delphi DSP-based pluggable modules are planned to be available beginning in Q2 CY2024.

Optomind and MaxLinear show 800G LRO optical and AOCs

At #OFC24, MaxLinear and Optomind will demonstrate 800G half re-timed linear receive optics (LRO) optical modules and AOCs leveraging Optomind’s patented optical assembly capabilities and MaxLinear’s Keystone Multimode 5nm 800G Tx-ONLY DSP with integrated VCSEL drivers. 

• 
  800G half re-timed LRO optical modules and AOCs play a crucial role in enabling ultra-high-speed data transmission over optical fiber networks, meeting the growing demand for bandwidth in modern communication and computing systems. 
• The LRO design involves a partial re-timing of the received optical signal to improve its quality and reliability. 
• In active optical cables, this eliminates the need for separate transceivers and optical connectors, providing a cost-effective and robust solution for short-reach optical connections. 
• The demonstration at OFC2024 will showcase an LRO optical module/AOC solution with significantly reduced latency and best-in-class power consumption for an 800G transceiver.

Optomind's optical engine solution integrates optics and mechanics seamlessly. With its patented prealigned OSA architecture, Optomind revolutionizes manufacturing processes, eliminating the need for complex alignment equipment. 

“The AI/ML market demands solutions with lowest possible power and latency to scale effectively,” said Drew Guckenberger, VP of High Speed Interconnect at MaxLinear. “LRO solutions are one vehicle to achieve those goals. Through our continued, strong partnership with Optomind, we are pleased to be able to quickly provide a volume capable LRO solution for our key customers, addressing their real, immediate needs in the space.”

Coherent intros 100G ZR QSFP28-DCO module for outdoor deployments

Coherent Corp. introduced its I-temp 100G ZR QSFP28 digital coherent optics (DCO) transceiver designed for deployment in outdoor street cabinets and pole-mount physical plants in edge and access networks with a wider range of temperatures.

These transceivers can be installed directly onto already deployed access network equipment with QSFP28 ports such as optical line terminals (OLTs) and aggregation switches and routers for midhaul and backhaul applications.

The new transceiver uses Coherent's Steelerton digital signal processor (DSP), a purpose-built DSP component family launched in 2022. The new module is optimized for the lowest power consumption in a compact transceiver size. The DSP is paired with an efficient silicon photonics optical front-end and a power-optimized tunable laser, now enhanced to support a wider operating temperature range, resulting in module power consumption of less than 6 W at a case temperature of 85°C.

In 2023, Coherent was the first to offer this solution in C-temp (commercial temperature: 0°C to 70°C). The company is now the first in the industry to extend its performance to the industrial temperature range to enable even broader deployment opportunities.Coherent Corp. (NYSE: COHR), a leading provider of high-performance optical networking solutions, today introduced its versatile I-temp 100G ZR QSFP28 digital coherent optics (DCO) transceiver.

“The Coherent 100G ZR QSFP28-DCO platform is built on our internally developed 100G digital signal processor. We are excited to continue to add new product variants that serve our customers’ needs, like the high transmit output power version for metro ROADM applications that was announced last fall and the industrial operating temperature version that we are announcing today,” said Matthias Berger, VP, Coherent Technology. “Since the launch of these products, we’ve experienced tremendous interest, and we believe that with these new versions, we can continue to grow the number of applications and use cases for the 100G ZR QSFP28-DCO transceiver family, pushing coherent technology ever further toward the network edge.”

Eoptolink demos 200G/lane LPO

At #OFC24, Eoptolink will show linear-drive pluggable optics (LPO) operating at 200G per lambda, demonstrating how half-retimed solutions are a viable alternative for higher data-rate applications.

LPO transceivers are designed without DSPs or CDRs, resulting in lower power consumption and significantly less latency. Eoptolink 800G OSFP DR4 LPO transceivers utilize a silicon photonics PIC that transmits 4 parallel channels at 200Gbps. Reduced power and latency performance has resulted in an increasing interest in LPO modules for switch to server and GPU to GPU connectivity in High Performance Computing applications such as AI and ML clusters.

In addition, Eoptolink has launched the 2nd generation of its 100G/lane 800G and 400G LPO products for single-mode applications in OSFP, QSFP-DD and QSFP112 form-factors. The second generation of Eoptolink 800G and 400G LPO products enables users to achieve full TP2 compliance at the optical transmit interface of the modules. Both gen1 and gen2 LPOs are now available in high volume production.

"The exploration of LPOs in NIC and GPU applications are becoming increasingly popular, modern ASICs on the NICs allow full TP2 and TP3 compliance at the optical interface and at the same time LPOs offer cost, power and latency advantages", said Sean Davies, VP Sales, Eoptolink Technology Inc., Ltd. "Eoptolink is a founding member of the recently launched LPO MSA to help to develop the specifications for networking equipment and optics, which are required to enable a broad ecosystem of interoperable LPO solutions."
