ZeroFlap Optical Transceivers

Credo’s ZeroFlap (ZF) Optical Transceivers are engineered to enhance the management and mitigation of optical link flaps delivering greater network stability and operational efficiency for AI backend fabrics. When used in conjunction with Credo PILOT software and integrated with the ZeroFlap Host SDK for telemetry harvesting and coordination, ZF Optical Transceivers form an integral part of Credo’s complete ZeroFlap networking solution.

ZeroFlap Optical Transceiver Products

 

Exceeding standard IEEE requirements, ZeroFlap Optical Transceivers deliver enhanced link telemetry reporting and autonomous link health monitoring—providing comprehensive network visibility and early warning of potential issues. The non-volatile event log embedded in the transceiver is a critical resource for accurately tracing historical network events, enabling efficient cluster maintenance.

ZeroFlap Optical Transceiver Features

As AI cluster sizes scale beyond 1GW, transceiver reliability has proven to be a limiting factor in cluster stability and uptime. Furthermore, customer demand for bare-metal GPU instances, limits the operators’ ability to manage GPU facing optics. Credo’s ZeroFlap (ZF) optical transceivers solve this through a multitude of features.
