SFP 1.25G BIDI 1550Tx/1310Tx 40KM LC

General Description of SFP 1.25G BIDI 40KM LC:

Small Form Factor Pluggable (SFP) transceivers are compatible with theSmall Form Factor Pluggable Multi-Sourcing Agreement (MSA), The transceiver consists of fivesections: the LD driver, the limiting amplifier, the digital diagnostic monitor, the DFB laser andthe PIN photo-detector .The module data link up to 40km in 9/125um single mode fiber. A 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) or disable/fault information via I2C register access.

SFP (Small Form-factor Pluggable) 1.25G BIDI (Bidirectional) 1550Tx/1310Tx 40KM LC refers to a specific type of optical transceiver module commonly used in networking equipment. Let's break down the terminology:

SFP: This stands for Small Form-factor Pluggable. SFP modules are hot-swappable input/output devices that plug into a physical port on a networking device (such as a switch, router, or network interface card) to connect it to a fiber optic or copper networking cable.

1.25G: This indicates the data transfer rate supported by the module, which is 1.25 gigabits per second. This is a common speed for many networking applications, including Ethernet.

BIDI: Bidirectional communication means that data is transmitted and received on the same fiber strand but in opposite directions. BIDI technology is commonly used in situations where only one fiber strand is available for communication, such as in some fiber-to-the-home (FTTH) installations.

1550Tx/1310Tx: This refers to the wavelengths at which the module transmits data. In this case, the module can transmit data at two different wavelengths: 1550 nanometers (nm) and 1310 nm. These wavelengths are within the typical range used for fiber-optic communication. 40KM: This indicates the maximum distance over which the module can reliably transmit data. In this case, the module is capable of transmitting data over a distance of up to 40 kilometers using single-mode fiber optic cable.
