WEST HILLS, Calif.–(BUSINESS WIRE)–Source Photonics, a leading vendor of optical connectivity products, announced a range of 800G optical transceivers for Datacenter and Telecom applications during the OFC 2021 virtual event today.

“Multiple 800G transceiver offerings in different form factors and optical interfaces will be available to support optical connectivity between transport, routing and switching equipment”

As the initial wave of widescale deployment of 400G is taking place in datacenters, hyperscale datacenter customers are already looking into 800G and beyond, together with the release of 25.6T switching ASIC, to further support the increasing demand for bandwidth-intensive applications. The 800G client interfaces will not only double port density over currently available 400G transceivers, but also are expected to further reduce per gigabit power and cost over equivalent 400G client interfaces.

Source Photonics is deeply engaged with key customers to ensure these solutions meet market requirements for these critical applications. Source Photonics leverages vertical integration for optical chips and assembly, which enables industry leading performance and power consumption. The portfolio of 800G transceivers for Switching and Routing applications includes:

800G DR8 OSFP & QSFP-DD800

  • Support 500m, 2km and 10km reaches for 800G-DR8, 800G-DR8+ and 800G-DR8++, respectively
