FS.COM 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 1310nm FP laser(the 1490nm 

DFB laser)and the PIN/TIA .The module data link up to 20km in 9/125um Single-mode fiber. 

This transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-Bi-dirictional 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.

1000BASE-BX SFP Transceiver Module (SMF, 1310nm-TX/1490nm-RX, 20km, LC, DOM)

The 1000BASE-BX SFP transceiver provides up to 20km of 1000Base-BX throughput over single-mode fiber (SMF) using 1310nm-TX/1490nm-RX wavelengths via LC simplex connectors. This bi-directional unit must be used with another transceiver or network equipment of complementary wavelengths. It provides 1000BASE Ethernet connectivity options for Fast Ethernet, Telecom and Data Centers.
