The Box CWDM Mux/Demux Module is a passive wavelength-division multiplexing component designed to transmit multiple optical wavelength channels over a shared fiber. Based on CWDM technology, it combines individual wavelength signals onto a common port in a MUX configuration and separates them into individual channels in a DEMUX configuration.
CWDM Wavelength Multiplexing
Supports transmission of multiple optical wavelength channels over a common fiber link.
MUX and DEMUX Functions
Available for combining individual wavelengths or separating multiplexed signals at the receiving side.
20nm CWDM Channel Spacing
Designed around standard coarse wavelength-division channel spacing for multi-wavelength transmission.
Passive Optical Operation
Requires no external electrical power for wavelength multiplexing or demultiplexing.
Box-Type Package
Provides mechanical protection for internal optical components and facilitates installation in network equipment.
Fiber Capacity Expansion
Enables multiple optical channels to share existing fiber infrastructure, helping increase fiber utilization.
Flexible Configuration
Channel count, wavelengths, connectors, pigtail length, and enclosure size can be configured according to system requirements.

A Box CWDM Module is a passive optical device that combines or separates multiple CWDM wavelength channels and packages the optical components inside a protective enclosure.
A MUX combines several wavelength channels onto one common fiber, while a DEMUX separates the multiplexed signal back into individual wavelength channels.
CWDM wavelengths are typically arranged with a nominal 20nm spacing between adjacent center wavelengths. The exact operating wavelengths depend on the selected channel configuration.
No. A standard CWDM Mux/Demux is a passive optical component and does not require an external electrical power supply.
CWDM allows several wavelength channels to share one fiber, which can increase the transmission capacity of existing fiber infrastructure without requiring a separate fiber for every service.
It can be integrated into optical transmission equipment, fiber distribution boxes, cabinets, telecom nodes, enterprise networks, and other wavelength-division multiplexing systems.
Yes. Different channel counts and wavelength combinations can be configured according to network requirements, subject to the available product design.
Typical parameters include channel count, center wavelengths, passband, insertion loss, channel isolation, ripple, PDL, return loss, directivity, connector type, fiber length, package dimensions, operating temperature, and optical power.
