4-Channel LWDM Module

4-Channel LWDM Module (Long Wavelength Division Multiplexing) is a device used in optical communication systems for transmitting and multiplexing 4 long-wavelength optical signals simultaneously. This module usually consists of a long wavelength division multiplexer (LWDM Mux) and a long wavelength demultiplexer (LWDM Demux). The long wavelength demultiplexer combines the long wavelength optical signals from different channels into a composite signal, while the long wavelength demultiplexer demultiplexes the composite signal into four separate long wavelength signals.

The main purpose of the 4-Channel LWDM Module is to realize multi-channel multiplexing and demultiplexing of optical signals to improve the transmission capacity and bandwidth utilization of optical fiber networks. By multiplexing and demultiplexing in the wavelength dimension of optical signals, multiple long-wavelength signals can be transmitted simultaneously to meet the needs of high-speed data transmission and communication.

In this module, the optical signal of each channel usually operates within a specific wavelength range. Common wavelength ranges include C-band (1530 nm to 1565 nm) or L-band (1570 nm to 1610 nm). Specific wavelength ranges and channel spacing can be selected and customized based on application requirements.
