The Finisar FTLF8528P2BCU is a high-performance Small Form-factor Pluggable (SFP+) optical transceiver designed for 8.5 Gbps Fibre Channel applications. While it is fully compatible with 1000BASE-SX Gigabit Ethernet standards, its primary design focus is storage area network (SAN) connectivity. The module operates at a nominal wavelength of 850nm over multi-mode fiber (MMF), utilizing a short-wave VCSEL laser transmitter. It is engineered to support a triple-rate interface, allowing for auto-sensing and backward compatibility with 4.25 Gbps (4GFC) and 2.125 Gbps (2GFC) protocols, ensuring flexibility in heterogeneous storage environments.The unit features a standard duplex LC connector and supports link distances of up to 150 meters on OM3 multi-mode fiber and up to 190 meters on OM4 fiber. The FTLF8528P2BCU fully supports Digital Diagnostic Monitoring (DDM) according to the SFF-8472 standard, providing real-time monitoring of transceiver temperature, laser bias current, optical transmit power, and received optical power. This hot-swappable module is optimized for low power consumption and high reliability, making it an essential component for high-density switching and director platforms. It is compliant with the SFP+ Multi-Source Agreement (MSA) and meets Class 1 laser safety standards.
