80km 1.25Gbps BIDI SFP Fiber Optic Transceiver with TX1490/RX1550nm Wavelength for Long-Distance Optical Links

1.25G BIDI SFP TX1490/RX1550nm (TX1550/RX1490nm) 80KM LC SMF Fiber Optic Transceiver

1.25G BIDI SFP TX1310/RX1550nm(TX1550/RX1310nm) 80KM LC SMF Fiber Optic Transceiver Small Form Factor Pluggable (SFP) transceivers are 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 PIN photo-detector. The module data link up to 80km in 9/125um single mode fiber.

The optical output can be disabled by a TTL 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.
