General Description of SFP 1.25G LC:
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 DFB laser, and the PIN photo-detector. The module data link up to 80km in 9/125um single mode fiber. 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 from 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.
The SFP 1.25G BiDi 1550Tx/1490Rx 80KM LC transceiver is a specific type of small form-factor pluggable (SFP) transceiver commonly used in data communication applications, particularly in fiber optic networks. Here's a breakdown of its specifications:
- Data Rate: 1.25 gigabits per second (Gbps)
- BiDi (bidirectional): This means the transceiver is capable of both transmitting and receiving data over a single fiber optic strand.
- It utilizes two different wavelengths for transmission and reception: 1550 nanometers (nm) for transmitting (Tx) and 1490nm for receiving (Rx).
- Maximum Transmission Distance: 80 kilometers (km). This specifies the maximum distance over which the transceiver can reliably transmit and receive data.
- LC Connector: LC connectors are a type of fiber optic connector commonly used in networking equipment. They are small, easy to use, and provide low insertion loss.
