Inphi ramps shipments of 400ZR and ZR+ QSFP-DD transceivers

Inphi announced the commercial availability and production ramp of its COLORZ II 400ZR QSFP-DD pluggable coherent transceivers for cloud data center interconnects (DCIs). Inphi also confirmed that a longer reach variant, COLORZ II 400G ZR+, which extends the reach of COLORZ II from 120km to about 400km, is in final stages of qualification and expected to be commercially available starting next month.

COLORZ II 400ZR and 400ZR+ enable a dramatic increase in switch rack capacity while reducing power consumption by up to 80%. COLORZ II delivers up to 14.4Tb of capacity per rack unit, compared to 2.4Tb or 3.6Tb per RU for competing solutions, representing a 4-6x increase in throughput per chassis. COLORZ II ZR and ZR+ achieve drastically improved density through higher levels of silicon photonics integration as well as much lower power consumption across all coherent transceiver elements.

“COLORZ II 400G ZR and ZR+ are the enabling technology for next-gen data center interconnects,” said Josef Berger, AVP, Product Marketing, Optical Interconnect at Inphi. “This is an important step in realizing our vision of 'The Cloud is the Network™'. The commercial availability and production ramp of COLORZ II 400G ZR and ZR+ demonstrates Inphi's industry leadership as we continue to create solutions that dramatically increase the speed of data movement, while keeping the power and cost low.”

According to market research firm Cignal AI, shipments of 400G ZR and ZR+ modules will expand at a >100% Compound Annual Growth Rate (CAGR) and provide one-third of worldwide WDM connectivity in 2025.

“The commercial availability of COLORZ II 400ZR makes IP over DWDM viable for network operators,” said Andrew Schmitt, Directing Analyst. “This enables an entirely new type of distributed data center architecture for the cloud and is the first step towards broad adoption in both cloud and traditional service provider networks.”

Inphi said its COLORZ II represents the culmination of several important industry firsts:

  • First 400G single-chip, coherent silicon PIC to include all transmit and receive functions
  • First low-cost, passive alignment of fiber to the PIC using traditional optics, eliminating the need for complex active alignment
  • First low-power, high-performance 7nm CMOS-based coherent DSP enabling 400ZR and 400ZR+ extended reach 100/200/300/400G modes
  • First integrated, industry-standard firmware management interface enabling full performance monitoring of DCI or transport systems without direct optical module support

OIF published the Implementation Agreement (IA) for a low-cost, 400ZR coherent optical interface. OIF launched the 400ZR project in response to requests from large-scale data center operators and their suppliers for an interoperable coherent interface that transports 400 Gigabit Ethernet over longer distances. Traditional network operators also became interested in 400ZR for their metro needs. Based on their different requirements, OIF developed...


NeoPhotonics cover 800km reach with 400ZR+ QSFP-DD transceiver

NeoPhotonics demonstrated that its 400ZR+ QSFP-DD coherent pluggable transceiver can effectively transmit at a 400 Gbps data rate over a distance of 800 km in a 75GHz-spaced DWDM system with more than 3.5 dB of OSNR margin in the optical signal. 

This 400ZR+ coherent pluggable transceiver module is based on NeoPhotonics high performance coherent optics and its ultra-pure color tunable laser, and achieves a reach of 800 km while staying within the power consumption envelope of the QSFP-DD module’s power specification. 


  • This 800 km transmission demonstration was carried out on NeoPhotonics Transmission System Testbed and utilized 75 GHz spaced channels. 
  • The QSFP-DD uses NeoPhotonics Silicon Photonics based Coherent Optical Subassembly (COSA) and its ultra-narrow linewidth Nano-ITLA tunable laser. 

NeoPhotonics said the longer reach was enabled by the superior performance of these optical components along with a commercial digital signal processor (DSP) using proprietary forward error correction (FEC). The COSA exhibits low insertion loss and low impairments, making efficient use of the optical signal. The Nano-ITLA tunable laser exhibits ultra-low phase noise and low power consumption. Additionally, these components allow NeoPhotonics 400ZR+ QSFP-DD transceiver module to operate at a case temperature of up to 80 degrees Celsius, which is ten degrees higher than conventional telecom modules, thereby reducing air flow requirements resulting in lower fan speeds and reduced power for cooling in data centers.

NeoPhotonics QSFP-DD modules are in the final stages of qualification and have passed 2000 hours of High Temperature Operating Life (HTOL) and other critical tests per Telcordia requirements. The Company expects these modules to be at General Availability (GA) within the second quarter of 2021.

NeoPhotonics 400ZR+ QSFP-DD transceivers are designed to operate in 75 GHz spaced DWDM systems using 64 Channel Arrayed Waveguide Grating MUX and DMUX filters, such as those made by NeoPhotonics. In this case, a fully loaded fiber operating in the C-Band would provide a total of 25.6 Terabits per second (Tbps) capacity. To further maximize the data capacity of optical fibers, NeoPhotonics has developed an enhanced version of its ultra-low noise laser in a C++ LASERTM module, which has a tuning range of 6 THz, enabling a total fiber capacity of 32 Tbps using 400Gbps transceivers and 75 GHz channel spacing.

“We are excited to extend the operation of our QSFP-DD Coherent transceiver into metro and regional applications in this 400ZR+ configuration,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “Advances in our ultra-pure light tunable laser, our silicon photonics integrated COSA and electronic DSPs have inexorably decreased the size, power and cost of coherent transmission such that a coherent transceiver capable of up to long haul distances can fit in the same form factor as a current generation high density client side pluggable module, such as a QSFP-DD. This has been a sea change for Data Center Interconnect networks, and we believe it will also bring fundamental changes to metro and regional networks,” concluded Mr. Jenks.

NeoPhotonics ships QSFP-DD 400G ZR modules

NeoPhotonics announced the availability of its extended case temperature QSFP-DD 400G ZR modules.

NeoPhotonics said the new 400G ZR modules leverage its Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tunable laser.  Each of these components can be operated over a wide module case temperature range up to 80C. This enables the Neophotonics 400G ZR modules to be deployed in extended temperature data center environments while reducing cooling requirements and fan power.

“The ability of 400G ZR vendors to offer thermally-optimized designs capable of supporting higher case temperatures will significantly help reduce system cooling requirements,” said Dr. Hacene Chaouch, Distinguished Engineer at Arista Networks. “This is an important consideration for implementing power efficient data center interconnect architectures.” 

“We are pleased to support customers with high-performance 400G ZR modules that operate across a wide thermal envelope, without sacrificing optical performance.” said Tim Jenks, Chairman and CEO of NeoPhotonics.  “By utilizing our leading high-speed coherent components technology and optimizing the entire optics suite through in-house design, we are able to favorably benefit data centers need to reduce power consumption and improve environmental sustainability,” concluded Mr. Jenks.

DARPA seeks to boost domestic manufacturing of structured ASICs

The U.S. Defense Advanced Research Projects Agency (DARPA) is launching an industry collaboration with Intel to expand access to domestic manufacturing capabilities for custom chips for defense systems. 

DARPA's Structured Array Hardware for Automatically Realized Applications (SAHARA) program is partnership with Intel and academic researchers from University of Florida, University of Maryland, and Texas A&M to develop U.S.-based manufacturing capabilities to enable the automated and scalable conversion of defense-relevant field-programmable gate array (FPGAs) designs into quantifiably secure Structured ASICs. 

SAHARA will also explore novel chip protections to support the manufacturing of silicon in zero-trust environments. While FPGAs are widely used in military applications today, Structured ASICs deliver significantly higher performance and lower power consumption.

For its part, Intel said it will use its structured ASIC technology to develop platforms that significantly accelerate development time and reduce engineering cost compared to traditional ASICs. 

Intel plans to manufacture these chips using its 10nm process technology with the advanced interface bus die-to-die interconnect and embedded multi-die interconnect bridge packaging technology to integrate multiple heterogenous die in a single package.

Intel eASIC devices are structured ASICs, an intermediary technology between FPGAs and standard-cell ASICs. 

"We are combining our most advanced Intel eASIC structured ASIC technology with state-of-the-art data interface chiplets and enhanced security protection, and it’s all being made within the U.S. from beginning to end. This will enable defense and commercial electronics systems developers to rapidly develop and deploy custom chips based on Intel’s advanced 10nm semiconductor process," stated José Roberto Alvarez, senior director, CTO Office, Intel Programmable Solutions Group.

SAHARA is a critical program supporting the Department of Defense (DoD) microelectronics Roadmap led by the Under Secretary of Defense for Research and Engineering – USD(R&E) – to define, quantify, and standardize security while strengthening domestic semiconductor manufacturing. The Rapid Assured Microelectronics Prototypes-Commercial (RAMP-C) and State-of-the-Art Heterogeneous Integration Prototype (SHIP) projects are also integral to the DoD Roadmap.

“The structured ASIC platforms and methods developed in SAHARA together with the advanced packaging technology developed in SHIP will enable the U.S. Department of Defense to more quickly and cost effectively develop and deploy advanced microelectronic systems critical to DoD modernization priorities,” said Brett Hamilton, deputy principal director for Microelectronics in USD(R&E).

NEC qualifies subsea repeaters and cables for 24 fiber pairs

 NEC and its subsidiary OCC Corporation have completed full qualification of subsea repeaters and optical cable containing up to 24 fiber pairs (FPs) (48 fibers). The new qualification is a 50% improvement in fiber count over the 16 fiber pair systems generally available today. 

Only minor modifications were needed to NEC's existing repeater and cable designs. Keeping NEC's quadruple pump redundancy in the repeater (established more than 10 years ago) and maintaining OCC's outstanding cabling performance has resulted in cabled attenuations lower than 0.150dB/km. Low attenuation is critical to achieve large spectral efficiency as well as lower power consumption.

NEC said the qualification will allow for the construction of subsea telecom cables with superior traffic capacity while reducing the cost per bit of the wet plant. The development is fully in line with SDM (Space Division Multiplexing) system architectures. 

"As global demands for capacity and FP flexibility continue to soar, NEC is committed to helping our customers to build up their subsea networks with large spectral efficiency, lower power consumption and large-scale subsea connectivity," said Yoshihisa Inada, Deputy General Manager and Head of Subsea Technology Development at NEC's Submarine Network Division.  "We continue to evaluate multiple technical options to further increase capacity and reduce the cost/bit of the networks."

OCC's 24 fiber pair cable can be manufactured using a wide range of existing optical fibers, according to the needs of each new cable system. Each fiber can be visually identified using a field-proven combination of ring marking and conventional fiber coloring, first introduced in 2013. Furthermore, in OCC cable, the fiber's transmission performance is completely unaffected, either by the fiber marking or cabling processes.

"We have concluded that the use of our fibers in OCC's 24 pair cable results in a cabled attenuation matching the nominal value. We are confident that our ultra-low-loss fibers can contribute to achieve large capacity, high spectral efficiency and low power consumption in transoceanic networks," said Dr. Masashi Onishi, General Manager at Optical Fiber and Cable division of Sumitomo Electric Industries Ltd.

"To support growing bandwidth, next generation subsea systems will offer Petabit-scale transmission. To achieve the required performance, cabling processes must capture the advantaged optical attenuation and large effective area of our ultra-low-loss fibers. OCC's cabling process for 24 fiber pairs works with our high quality fiber to meet the challenge," said Dr. Bernhard Deutsch, VP & GM, Optical Fiber & Cable, Corning Incorporated.

NEC targets subsea cables to 24 fiber pairs and beyond

NEC and its subsidiary OCC Corporation completed full qualification of subsea repeaters and optical cable containing up to 20 fiber pairs (40 fibers). This represents a 25% improvement in fiber count over 16 fiber pair systems previously built by NEC. NEC said it achieved this milestone with only minor modifications to its proven repeater and cable designs. This was done by optimizing key repeater components, and by proving that its existing cable...

Zayo upgrades its fiber network in Vancouver

Zayo announced a significant expansion to its infrastructure in Vancouver, British Columbia with two key projects: a network upgrade to 100G and an increase in the fiber capacity to its existing terrestrial route between Vancouver and Seattle, scheduled for completion by mid-year of 2022.
