SFP BIDI Transceiver,Tx1550/Rx1310,155M,20km

PRODUCT DESCRIPTION
F-tone Networksi’s BXCS-Bxx03-20xx Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), The transceiver consists of four sections: the LD driver, the limiting amplifier, the FP laser and the PIN photo-detector. The module data link up to 20KM in 9/125um single mode fiber.
The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner.
