Keysight and Credo collaborate on 800 GigE testing

Keysight Technologies has collaborated with Credo to enable data center operators  and the respective supply chain to validate the readiness of data center equipment in complex 800 Gigabit Ethernet (GE) environments.

The 800GE testing equipment is comprised of Keysight's G800GE Forward Error Correction- (FEC) Aware and Compliance test system using Credo’s Active Electrical Cable (AEC) connectivity solution. The AECs are key to ensuring signal integrity for copper cabling lengths greater than two meters. Long reach capabilities are essential to connect the data center servers to a top of rack (ToR) switch.

"The move to 800GE presents DCOs and vendors in the supply chain with new challenges to validate chips, optical transceivers, or networking equipment port electronics,” said Ram Periakaruppan, vice president and general manager, Keysight's Network Test and Security Solutions group. "The unique combination of the Keysight G800GE test system and Credo's 800GE AEC technology addresses the interoperability challenges and enables the data center community to accelerate validation of 800GE devices and network infrastructure.”

"Keysight's G800GE test system with 400GE/200GE/100GE per port fan-outs meets the performance and verification needs of 800GE interconnect and infrastructure," said Don Barnetson, vice president of product at Credo. "It is very exciting to see Keysight leverage our HiWire LP CLOS AEC 800 in their 800GE test and validation platform. The performance of this AEC is not only enabling next generation hypsercale data center implementations, but is also a valued component of the infrastructure making those implementations possible.”

Finland's research net carries 800G over 2000 km with ADVA

The Finnish University and Research Network (FUNET) successfully transmitted a 800 Gbps channel over 2,000 km over its live network using the ADVA FSP 3000 TeraFlex CoreChannel.

The field trial used ADVA’s new CoreChannel sled featuring 140GBd sub-carrier technology and 150GHz channel spacing. ADVA said the trial set a new benchmark for the industry's longest reach for a single-channel 800 Gbps transmisison.

“ADVA’s FSP 3000 TeraFlex CoreChannel at 800 Gbps speed delivered impressive reach during our tests and was stable throughout the month-long test period when we ran it on our nationwide ADVA open line system. The new 800 Gbps channel technology will give us more flexibility to choose optimum modulation per use case to improve spectral efficiency. And, more importantly, it maps efficiently to 400GbE client services,” said Jani Myyry, senior network specialist, CSC/FUNET. 

“This field trial demonstrates that our network can smoothly support future requirements and deliver even more to our users in the Finnish research and education community. It also will strengthen our confidence that the first multi-Terabit services we aim to deliver early next year together with other Nordic research and education networks can be implemented successfully.”

“It’s fantastic to see our FSP 3000 TeraFlex™ with CoreChannel™ sled pass this major test with such flying colors. Even over the FUNET network’s longest distances, the solution surpassed expectations and showed how incredible speeds are now possible at the lowest possible cost per bit per kilometer,” commented Cornelius Fürst, director, product line management, ADVA. “One of the reasons our FSP 3000 TeraFlex™ CoreChannel™ is able to provide such great long-haul performance is that it carries data at 800Gbit/s using a 150GHz window. Not only does this help to reduce complexity and avoid stranded bandwidth, but it also makes the technology future-proof. 150GHz is the channel spacing that offers the best balance between fiber capacity and optical reach. That’s why it’s gaining traction across the industry and why our open FSP 3000 TeraFlex™ CoreChannel™ sled is ready for new innovation further down the line.”

Credo announces 800G HiWire Active Electrical Cables

Credo announced its new 800G HiWire LP CLOS Active Electrical Cable (AEC) for distributed, disaggregated chassis (DDCs) used in hyperscale infrastructure. 

The new 8 x 112G per lane copper cable interconnect is the first member of Credo’s 800G AEC family.

At just 32AWG, 800G AECs are about as thick as standard Cat6e cabling. This narrower gauge reduces cabling volume by up to 75% versus passive copper DACs. LP CLOS AECs are available in lengths up to 2.5m. Credo’s new AECs consume half as much power as optical cabling solutions and feature superior reliability with up to 100 million hours of Mean Time Between Failure (MTBF).

The LP CLOS AEC 800 PAM4 cables come in QSFP-DD800 (Quad Small Form Factor Pluggable Multi-Source Agreement Group) and OSFP (Octal Small Form Factor Pluggable) types. Integrated Credo retimers enable the cable to achieve high performance without needing additional external components, simplifying the design and lowering system cost and power. The new 800G AECs are identified by their distinctive HiWire purple color sheath. 

Credo is sampling the LP CLOS AEC 800 now with general availability expected in early 2022.

Credo says that  at 400G and higher, AECs offer greater signal integrity and break through the physical weight, bend radius, and range limits of passive copper Direct Attached Cables (DACs). 

“Credo sees 800G as the point where passive DACs hit the wall – they are far too thick and rigid for many customer applications and impose a high cost and engineering burden on switch manufacturers,” said Don Barnetson, Vice President of Product at Credo. “Credo’s new 800G LP CLOS AECs route like Cat6 cables and offer up to 100 times better reliability and half the power of optical cabling solutions. The future of connectivity is clearly purple.”

OSFP MSA completes specification for 800G modules

The Octal Small Form Factor Pluggable (OSFP) Multi Source Agreement (MSA) group has published its OSFP 4.0 Specification for 800G OSFP modules. 

While the OSFP module was designed from the beginning to support 800G performance, the OSFP 4.0 specification adds support for dual 400G and octal 100G breakout modules with dual LC, dual Mini-LC, dual MPO and octal SN/MDC fiber connector options.

“At 800G, the number of use cases involving aggregation or breakouts are increasing,” said Andreas Bechtolsheim, OSFP MSA Chair. “Being able to use existing standard fiber connectors for these breakout ports is a key issue since it avoids the optical performance impact and cost of fiber adaptor cables, splitter cables or patch panels.”

“Cloud operators have deployed tens of millions of LC and MPO fiber connectors with existing optics transceivers,” said Sameh Boujelbene, Senior Director at Dell’Oro Group. “A smooth transition from single port to dual port 400G optics in the 800G form factor requires backward compatibility with this large installed base of fiber connectors.”

“The ability to do rolling networking upgrades in existing cloud data centers is essential since cloud data centers are always on,” said Alan Weckel, Founding Technology Analyst at the 650 Group. “As the Cloud grows in size, the majority of equipment installed goes into existing facilities, a very different dynamic compared to previous upgrade cycles. Being able to install new network switches without replacing millions of installed fiber connectors is one of the most important issues customers are facing as they transition to 800G optics form factor modules.”

“The OSFP 4.0 specification offers customers compatibility with existing fiber connectors and a broad choice of potential optical breakout options, which will likely become even more important with the upcoming early adoption of 800GbE data center switching starting next year,” said Seamus Crehan, President of Crehan Research.

With the 800G OSFP module specification completed, the OSFP MSA has sponsored a working group that is defining 200G/Lane electrical specifications to support 1600G OSFP modules. When this activity is completed, this development will be merged into a future OSFP 5.0 Specification.

“We have received strong interest from OSFP MSA members to start the 200G/Lane Electrical Signaling Group,” said Brian Kirk, Director of Engineering, Amphenol Corp. “Based on the work done so far, we are confident that the OSFP module will be able to support 200G electrical signaling speed per lane in a backward compatible fashion.”

“1600G-OSFP enables next-generation switch designs with up to 57.6T bandwidth per rack unit,” said Nathan Tracy, Technologist at TE Connectivity. “It is remarkable that the OSFP can support this level of bandwidth density in a pluggable form factor.”

NeoPhotonics ships first coherent components for 800G and up

NeoPhotonics announced the first pilot shipments of Class 60 versions of its Coherent Driver-Modulator (CDM) and Intradyne Coherent Receiver (Micro-ICR) designed for the next generation of 96 GBaud and above systems supporting 800G rates.

NeoPhotonics said higher symbol rates increase data capacity while maintaining superior optical signal-to-noise ratio (OSNR) and reach performance, thereby enabling the highest speed-over-distance use. These new components are available in compact form factor packages suitable for use in pluggable modules and compact daughter cards. 

NeoPhotonics' Class 60 Coherent components extend the highest speed-over-distance performance of its existing Class 40 products by increasing the 3 dB bandwidth from 40 GHz to 60 GHz. These NeoPhotonics components work together to enable single wavelength data transmission near one Terabit per second over datacenter interconnect (DCI) distances, as well as 400~500Gbs transmission over long haul distances.

NeoPhotonics Class 60, polarization-multiplexed, coherent driver modulator (CDM) features a co-packaged InP modulator with four linear, high bandwidth, differential drivers, and is designed for low modulation voltage, or “V-Pi”, low insertion loss, and a high extinction ratio. The compact package is compliant with the form factor of the OIF Implementation Agreement #OIF-HB-CDM-01.0. NeoPhotonics Class 60 High Bandwidth Micro-Intradyne Coherent Receiver (Micro-ICR) is designed for 96 GBaud symbol rates, essentially tripling the rate of standard 100G ICRs. The compact package is compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.

These components work with NeoPhotonics’ “Nano” Ultra-Narrow Linewidth external cavity tunable laser, which cuts the size approximately in half compared to current Micro-ITLAs, while featuring industry-leading linewidth, low phase noise, and low electrical power consumption.

“We are pleased to be shipping initial quantities of our Class 60 coherent modulators and receivers, which along with our Ultra-Narrow Linewidth external cavity 'Nano' tunable laser, provide a complete suite of components enabling customers to efficiently implement 800Gbps per wavelength coherent communications systems,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “We are further extending the bandwidth of our Indium Phosphide coherent integration platform by developing Class 80 components for 130 Gbaud operation as we continue to serve the highest speed-over-distance applications,” concluded Mr. Jenks.
