The Credo ZeroFlap 400GBASE-DR4 Optical Transceiver is specifically designed for use in AI fabrics and data center networks where enhanced reliability and visibility are essential. When used in conjunction with Credo PILOT software and integrated with the ZeroFlap Host SDK for telemetry harvesting and coordination, the ZeroFlap 400GBASE-DR4 Optical Transceiver forms an integral part of Credo’s complete ZeroFlap networking solution.

Featuring optical performance compliant with IEEE 802.3-2022 Clause 124.7, the ZeroFlap 400GBASE-DR4 Optical Transceiver gives network operators flexibility to deploy optical connections up to 500m using parallel single mode fiber with MPO-12 optical connections. Enhanced link telemetry reporting and autonomous link health monitoring provide complete network visibility and offers advanced warning for impending problems. The non-volatile event log embedded in the transceiver is a critical resource for accurately tracing historical network events, enabling efficient cluster maintenance.
