1000BASE-BX SFP BiDi 1550nm-TX/1490nm-RX 120km DOM Simplex LC/UPC SMF Optical Transceiver Module

The 1000BASE-BX SFP BiDi 1550nm-TX/1490nm-RX 120km DOM Simplex LC/UPC SMF Optical Transceiver Module must be paired with the 1490nm-TX/1550nm-RX module for proper bidirectional communication over 120km. This setup ensures efficient data transmission using a single-mode fiber (SMF).

What’s BIDI optical transceiver?

A BiDi optical transceiver  (Bidirectional optical transceiver ) is a type of optical transceiver that enables data transmission and reception over a single optical fiber. Unlike traditional optical transceiver s, which require two separate fibers for sending and receiving signals, a BiDi transceiver  uses two different wavelengths to transmit and receive data simultaneously on the same fiber. This technology allows for bidirectional communication over a single fiber link, significantly optimizing fiber usage and reducing infrastructure costs.

Typically, BiDi transceiver s use two distinct wavelengths: one for transmission (TX) and another for reception (RX). For example, a common configuration might be 1310nm for transmission and 1490nm for reception. By utilizing these different wavelengths, BiDi transceiver s maximize the capacity of a single fiber, making them an ideal solution in scenarios where fiber resources are limited or expensive.

The main advantages of BiDi optical transceiver s include:

1. Fiber resource optimization: Reduces the need for additional fibers, lowering costs associated with fiber installation and maintenance.
2. Increased bandwidth utilization: Allows full bandwidth usage of a single fiber by transmitting and receiving data at different wavelengths.
3. Simplified network design: Reduces the complexity of network infrastructure, making it easier to deploy in environments with limited fiber availability.

BiDi transceiver s are widely used in various network applications, particularly in situations where there is a need for long-distance transmission, high data rates, or when optimizing fiber usage in dense network environments. They are commonly deployed in metro networks, data centers, and telecommunication systems.
