NeoPhotonics Announces Open ZR+ QSFP-DD Transceiver Sampling

SAN JOSE, Calif.–(BUSINESS WIRE)–NeoPhotonics Corporation (NYSE: NPTN), a leading developer of silicon photonic lasers, modules and subsystems, and advanced hybrid photonic integrated circuits for high-speed, bandwidth-intensive communication networks , today announced sample availability for its Open ZR+ QSFP-DD transceivers. Based on NeoPhotonics world-class optics, ultra-low-noise tunable lasers, and proven 400ZR design, the Open ZR+ version of the QSFP-DD uses Marvell® Deneb™ Coherent DSP (CDSP) to integrate error correction direct open industry standard (OFEC). NeoPhotonics is a contributor to the Multi-Source Open ZR+ Agreement (MSA), which defines interoperability specifications for OpenZR+.

By using OFEC, the rOSNR capability of NeoPhotonics transceivers is enhanced beyond the traditional CFEC 400ZR, enabling multi-range coverage in amplified networks. This can be applied to metro and IP over DWDM networks with extended reach scenarios, with data rate coverage from 100 Gb/s to 400 Gb/s. Additionally, there are a number of applications where the fiber reach may not exceed OIF ZR specifications, but due to older fibers, patch panels, and other deficiencies, loss budgets and Link degradation can exceed that of a standard 400ZR link. In these cases, NeoPhotonics’ OpenZR+ module can be used for 400G upgrades, where off-the-shelf solutions are impractical. More background information on coherent communications in plug-in modules can be found in a series of “Trends and Technology” presentations on the NeoPhotonics website.

“NeoPhotonics developed an OpenZR+ solution to leverage the benefits of IP over DWDM and because many customers want to use small form factor cohesive modules deeper into their networks,” said Tim Jenks, President and CEO. from NeoPhotonics. “Our Open ZR+ QSFP-DD transceivers combine extended network reach and interoperable OFEC with our proven optical component and transceiver designs to meet these needs. The transceivers also complement our proven 400ZR solutions, which have achieved design success with data center and cloud switch customers, with new Open 400ZR+ compliant QSFP-DD and OSFP modules. The ability to transmit 400 Gb/s over distances as long as 800 km and more cost-effectively is a real game-changer,” concluded Jenks.
