Fibre Channel transceivers, also called FC optical modules, are specialized devices designed for high-speed, reliable, and lossless data transmission within SANs. It acts as the key interface between Fibre Channel-specific devices—such as FC switches, host bus adapters (HBAs), and storage. Fibre Channel (FC) is a high-speed data transfer protocol providing in-order, lossless delivery of raw block data. 3bm, SFF-8636 and other standards; With low power consumption and small size, it is mainly used in 100G data center. Designed specifically for high-speed Storage Area Networks (SANs), Fiber Channel (FC) transceivers enable servers, switches, and storage systems to communicate with ultra-low latency and highly stable optical connectivity.
