Coherent announces general availability of 800G ZR/ZR+ transceiver

Coherent (COHR) announces general availability of its 800G ZR/ZR+ transceiver in QSFP-DD form factor. This launch reinforces the company’s commitment to next-generation optical networking. The 800G ZR/ZR+ addresses increasing demand for high-speed, efficient, and scalable metro, regional, and data center interconnect applications. Its pluggable form factor supports IP-over-DWDM deployments, enabling seamless integration into high-capacity routers and Ethernet switches. By eliminating standalone transport equipment, network operators achieve significant reductions in capital and operational costs. Supporting multiple operational modes, the module delivers 800G ZR/ZR+ transmission spanning more than 500 km in ZR mode, beyond 1000 km in high-performance ZR+ modes with probabilistic shaping and over 2000 km at lower data rates. Its advanced IC-TROSA optical engine utilizes proprietary Indium Phosphide chip technology, providing transmitter optical output power of -7dBm for OIF 800ZR and 0dBm for ROADM-based line systems. Unlike silicon photonics-based solutions, these performance levels are achieved without additional Erbium-Doped Fiber Amplifiers or tunable optical filters.
