What is CWDM Module?

Mux (Multiplexer) products combine several data signals into one for transporting over a single fiber. Demux (Demulitplexers) separate the signals at the other end. Each signal is at a different wavelength. WDM greatly increases the capacity of systems.

CWDM modules (Coarse Wave Division Multiplexing) combine or split up to 18 wavelengths into a single fiber. CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm.

CWDM Modules utilize thin-film coating and micro optics package technology. They are available in two main configurations: CWDM Multiplexer/Demultiplexer (Mux/Demux) modules and CWDM Add/Drop Multiplexer (OADM) modules.

CWDM Mux/Demux Modules are available in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 or more electronic devices, send them over a single optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices at the other end of the fiber optic link.

CWDM Add/Drop multiplexer Modules provide the ability to add or drop a single wavelength or multi-wavelengths from a fully multiplexed optical signal. This allows intermediate locations between remote sites to access the common, point-to-point fiber segment linking them. Wavelengths not dropped, pass-through the OADM and continue on in the direction of the remote site. Additional selected wavelengths can be added or dropped by successive OADMS as needed.

LFO offers thin film filter CWDM module for specific wavelengths or bands of wavelengths for applications from long haul to FTTP (fiber to the premise) applications. These components can be integrated into modules to meet customer requirements. We provide CWDM module with various kinds of Fiber Connectors and Fiber patch cord length and optional stainless tube package or standard box package to meet your requirement

We offer 1x4, 1x8, 1x6 CWDM Module and 1 channel, 2 channel, 4 channel CWDM Add/Drop multiplexer Module . Our CWDM modules are configured by number of channels for any customer -specify channel plan, and can be integrated with taps and detectors for a complete CWDM solution.

Besides CWDM Module, We also provide Fiber Circulator, Optical Switch, Optical isolator, PLC Splitter for your application.
