The LCP-1250B4QSRBTE transceivers are hot pluggable 3.3V Small-Form-Factor transceiver modules designed expressly for high-speed communication applications that require rates up to 1.25Gb/s. The transceiver is data rate transparent, which means it can support GbE (1.25Gb/s) as well as 1x Fiber channel (1.062Gb/s) operations. The LCP-1250B4QSRBTE transceivers are designed to be compliant with SFP Multi-source Agreement (MSA). Digital diagnostic monitoring functions (Temperature, VCC, TX optical power, TX laser bias current, and RX received optical power) compliant with SFF-8472 are also available. See order information for details. The post-amplifier of the LCP-1250 series also includes a Loss of Signal (LOS) circuit that provides a TTL logic-high output when the received optical level is below a preset LOS Assert threshold.
