The Finisar 1400729-0027 is a high-performance, short-range (SR) optical transceiver module designed for 10 Gigabit Ethernet and Fibre Channel applications. This SFP+ (Small Form-factor Pluggable Plus) module operates at a nominal wavelength of 850nm over multi-mode fiber (MMF). It supports data rates up to 10.5 Gbps, making it suitable for high-speed data center interconnects, storage area networks (SAN), and enterprise switching layers. The module is engineered for short-reach connectivity, supporting distances up to 300 meters on OM3 multi-mode fiber and up to 400 meters on OM4 multi-mode fiber.
The transceiver incorporates a Vertical-Cavity Surface-Emitting Laser (VCSEL) transmitter and a high-speed PIN photodiode receiver. It features a duplex LC optical connector and provides a high-speed serial electrical interface. The unit fully supports Digital Optical Monitoring (DOM) / Digital Diagnostic Monitoring (DDM), allowing network administrators to track real-time operational parameters such as laser bias current, optical output power, received optical power, internal temperature, and supply voltage. This hot-swappable module is designed for low power consumption and high reliability, ensuring seamless compatibility with networking hardware from major manufacturers that utilize Finisar-based OEM components. It complies with SFF-8431 and SFF-8472 standards and meets Class 1 laser safety requirements.
