hc’s sf-cxx30-40d(a) small form factor pluggable (sfp) transceiversare compatible with the small form factor pluggable multi-sourcingagreement (msa). the transceiver consists of five sections: the lddriver, the limiting amplifier, the digital diagnostic monitor, thedfb laser and the pin. the module data link up to 40km in 9/125umsingle mode fiber.
the optical output can be disabled by a ttl logic high-level inputof 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 aninput optical signal of receiver or the link status with partner.the system can also get the los (or link)/disable/fault informationvia i2c register access.
