DC-50 MBaud 850 nm Multimode LC Duplex SFP Transceiver

Currently Viewing:

The SFP transceiver provides system designers the ability to implement DC-50 MBaud data transmission over 2 km with (62.5 μm/125 μm) multimode fibers. The transceiver supports LC duplex connector and is lead free, RoHS compliant. Using the 2-wire serial interface defined in the SFF-8472 MSA, the AFBR‑57B4APZ provides real-time information on module temperature, transmitter supply voltage and receiver average input power.
