WDM, Mux/Demux and OADM Over view

CWDM Mux/Demux
The Coarse Wavelength Division Multiplexing-CWDM Mux/Demux is often a flexible plug-and-play network solution, which helps insurers and enterprise companies to affordably implement denote point or ring based WDM optical networks. CWDM Mux/demux is perfectly created for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks. CWDM products are popular in less precision optics and lower cost, un-cooled lasers with lower maintenance requirements. Weighed against DWDM and Conventional WDM, CWDM is much more economical and less power consumption of laser devices. CWDM Multiplexer Modules can be found in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 too much electronic products, send on them someone optical fiber and after that de-multiplex the signals into separate, distinct signals for input into gadgets across the opposite end for your fiber optic link.

DWDM Mux/Demux
The Dense Wavelength Division Multiplexing-DWDM Mux/Demux Modules are made to multiplex multiple DWDM channels into one or two fibers. Based on type CWDM Mux/Demux unit, with optional expansion, can transmit and receive as much as 4, 8, 16 or 32 connections of various standards, data rates or protocols over one single fiber optic link without disturbing one another. DWDM MUX/DEMUX modules offers the most robust and low-cost bandwidth upgrade on your current fiber optic communication networks.

OADM Add/Drop Multiplexer

WDM OADM Add/Drop Multiplexer is designed to organize the signal output at a predetermined wavelength from an optical line in the WDM system. These devices are called Add/Drop modules — WDM OADM (Optical Add/Drop Multiplexer).

The OADM module, extracting the desired signal, passes the rest of the emission unchanged. OADM modules are passive devices. Single-sided and dual-sided modules have a fundamental difference. Single-sided OADM can seize and add a signal in the line towards one multiplexer. Dual-sided OADM can establish a connection with two multiplexers, and the line will have no idle channels.
