Technologies and ProductsNeoPhotonics Corporation has announced sample availability for its Open ZR+ QSFP-DD transceivers. Based on its optical components, ultra-low noise tuneable lasers and 400ZR design, the Open ZR+ version of the QSFP-DD uses the Marvell® Deneb™ Coherent DSP (CDSP) to incorporate industry-standard Open Forward Error Correction (OFEC). The company says that by using OFEC, the rOSNR […]
News and BusinessAs part of its goal to drive multi-vendor interoperability of enhanced performance coherent pluggable modules, the OpenZR+ Multi-Source Agreement (MSA) Group today announced that it has published the OpenZR+ Rev 1.0 specification and a supporting whitepaper. This specification, based on high-gain oFEC, is designed to enable 100G to 400G line rates, multiplexing and extended reaches […]
Technical FeaturesHistory has shown that adoption of optical transceiver/transponder solutions accelerates when implementable standardization and interoperability are established. Coherent optical technology, traditionally a closed-system technology with proprietary implementations, is evolving towards a similar path, which will help carriers and hyperscale data center network operators by ensuring multiple suppliers for their critical components. This article reviews recent […]
