The WFT SFP transceiver modules is specifically designed for the high performance and cost-effectiveness integrated duplex data link over a single fiber. The high-speed laser diode and photo diode are provided as a light source and a detector, Respectively. An EEPROM is used to store the required data via the 2-wire serial CMOS EEPROM protocol. These Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA).
