TR857FA

The SAMSUNG TR857FA Small Form Factor Pluggable transceiver is designed for use in Gigabit Ethernet and Fibre Channel. TR857FA transceivers provide the LC receptacle is compatible with the industry standard LC connector. Transceiver also conforms to the industry SFP MultiSource agreement. For the good EMI performance, this transceiver uses the metal case.

The transmitter converts LVPECL TR857FA compatible electrical serial data into optical serial data. The transmitter contains the automatic power control (APC) circuit for the constant optical power over temperature. For the power control, monitoring PD is built into the TO-46 unit. Also, for the guaranteed Eye safety, automatic shut down function is contained. The receiver TR857FA converts the optical serial data into LVPECL compatible electrical serial data. The loss of signal (LOS) is TTL high when the received optical power is below the worst-case receiver sensitivity. Low indicates normal operation.
