BIDI SFP 1.25G 120km
ZKTel SFP-GE-BX SFP transceiver is compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The transceiver consists of five sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1490nm DFB laser (the 1550nm DFB laser) and the APD/TIA. The module data link up to 10km in 9/125um Single-mode fiber.
This transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-BiDi optical interface connector. An enhanced Digital Diagnostic Monitoring Interface compliant with SFF-8472 has been incorporated into the transceiver. It allows real time access to the transceiver operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage by reading a built-in memory with I²C interface. The optical output can be disabled by a LVTTL logic high-level input of 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 an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I²C register access.
