The OFSF10G10x-F31 is a 10G SFP+ optical transceiver designed in accordance with the Small Form Factor Pluggable Multi-Source Agreement (SFP MSA). It integrates a laser driver, limiting amplifier, DFB laser, and PIN photodetector to support optical data transmission over distances of up to 10 km using 9/125 μm single-mode fiber.
The module features a Tx Disable function, which allows the optical transmitter to be turned off by applying a TTL logic-high signal. It also provides a Tx Fault signal to report laser-related faults and a Loss of Signal (LOS) output to indicate a missing or insufficient received optical signal, helping monitor the status of the optical link.
