What is DWDM 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.

The DWDM Modules combine or split particular wavelengths into a single fiber and are idea for telecommunication and networking. DWDM technology use ITU standard 0.8nm/1.6nm spacing between the wavelengths, from 1529.55nm to 1560.61nm.

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

DWDM Mux/Demux Modules are available in 4, 6, 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.

DWDM Add/Drop multiplexer modules provide the ability to add or drop a single wavelength or multi-wavelengths from a fully multiplexed optical signal. These module allow 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 DWDM 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 requirementswith, We can provide various kinds of Fiber Connectors and Fiber patch cord length and optional stainless tube package or standard box package and to meet your requirement

We provide 1x4, 1x8, 1x16, 1x32 100 GHz and 200 GHz DWDM Module and 1 channel, 2 channel, 4 channel 100 GHz and 200 GHz DWDM Add/Drop multiplexer module. Our DWDM modules are configured by number of channels for any customer-specify channel plan, and can be integrated with taps and detectors for a complete DWDM solution.

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