NeoPhotonics has begun sampling its Open ZR+ QSFP-DD transceivers.
The Open ZR+ version of NeoPhotonic's QSFP-DD uses the Marvell Deneb Coherent DSP (CDSP) to incorporate industry-standard Open Forward Error Correction (OFEC).
NeoPhotonics said that by using OFEC, the rOSNR capability of its transceivers is improved beyond traditional 400ZR CFEC, allowing for multiple span coverage in amplified networks. This may be applied to metro and IP-over-DWDM networks with extended-reach scenarios, with data rate coverage from 100 Gbps to 400 Gbps.
In addition, there are a number of applications where the fiber reach may not exceed the OIF ZR specifications, but because of older fiber, patch panels and other impairments, the link loss and impairment budgets could exceed that of a standard 400ZR link. In these cases, NeoPhotonics’ OpenZR+ module can be used for 400G upgrades, where standard solutions are not practical.
“NeoPhotonics has developed an OpenZR+ solution to take advantage of the benefits of IP-over-DWDM and because many customers are interested in utilizing small form factor coherent modules deeper into their networks,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “Our Open ZR+ QSFP-DD transceivers combine an extended network reach and interoperable OFEC with our proven optical component and transceiver designs to address these needs. The transceivers also augment our proven 400ZR solutions, which have multiple design wins at cloud and data center switch customers, with new Open 400ZR+ compliant QSFP-DD and OSFP modules. The ability to transmit 400Gb/s over distances as long as 800km and more in a cost-effective manner is a real game changer,” concluded Mr. Jenks.
Lumentum to acquire NeoPhotonics for $918M amidst strong demand
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...
