1000BASE-BX SFP 1310nm-TX/1550nm-RX 20km Transceiver
SFP-1G-BX20-U-35 Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). Consists of 5 sections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the 1310nm FP laser (the 1550nm DFB laser) and the PIN/TIA.The module data link up to 20km in 9/125umSingle-mode fiber.
This transceiver meets the Small Form Pluggable (SFP) industry standard package utilizing an integral LC-Bi-directional 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, receive 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.
