SFP 1.25G Tx1490/Rx1310 40Km LC Transceiver

Gearlink’s SFP-GE-BX40 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 1310nm FP laser (the 1490nm DFB laser), and the PIN/TIA. The module data link up to 40km in 9/125um Single-mode fiber.

This transceiver meets the Small Form Pluggable (SFP) industry-standard package utilizing an integral LC-Bi-directional optical/bidi transceiverinterface 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 an I²C interface.

The optical output can be disabled by an LVTTL logic high-level input of Tx Disable, and the system also can disable the module via I²C. Tx Fault is provided to indicate the degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of the receiver or the link status with the partner. The system can also get the LOS (or Link)/Disable/Fault information via I²C register access.
