Amphenol SF-XGSF851202-000 SFP (1.25G) 1000BASE-SR Transceiver (Short Range 550m) 850nm Multi-Mode Optical Module (Duplex LC Connector) by Amphenol XGIGA (XGSF-8512-02D)

Amphenol XGIGA’s XGSF-8512-02D-F Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the VCSEL laser and the PIN photo-detector. The 850nm multimode SFP 1G/1.25G optical transceiver module drives links up to 550m using 50/125um multi-mode fiber such as OM3 and OM4 using the popular duplex LC connector style.

The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.
