Overview CWDM/DWDM Mux/Demux and OADM

by Fiber-MART.COM

CWDM/DWDM Mux/Demux and OADM are common fit in with Passive. CWDM and DWDM technology present an efficient approach to share one set of fiber strands as well as set together various communications interfaces like: 10G, SONET OC-192, STM-64, Fiber Channel 1G/2G/4G, Gigabit Ethernet, OC3/OC12 or OC48 and E1/T1, just by using different wavelengths associated with per channel. Thus they can expand the capacity with the network without laying more fiber. I would like to introduce the particular basical description of CWDM Mux/Demux, DWDM Mux/Demux and OADM.

 

You know, Mux (Multiplexer) products combine several data signals into one for transporting over the single fiber. Demux (Demulitplexer) separates the signals in the other end. Each signal is a some other wavelength.

 

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

OADM(Optical Add-Drop Multiplexer) is often a device found in WDM systems for multiplexing and routing different channels of fiber into or out of a single mode fiber (SMF). OADM was created to optically add/drop one or multiple CWDM/DWDM channels into a few fibers, provides the power to add or drop a single wavelength or multi-wavelengths from a fully multiplexed optical signal. This permits intermediate locations between remote sites gain access to the regular, point-to-point fiber segment linking them. Wavelengths not dropped pass-through the OADM and carry on towards the remote site. Additional selected wavelengths may be added or dropped by successive OADMS if required.

 

Luma Optics supplies a wide array of passive optics. The modules are customizable with a collection of WDM/CWDM/DWDM modules and CWDM OADM or DWDM OADM. Luma Optics may be the correct solutions to request guidance to be used of CWDM, DWDM or WDM technology. CWDM and DWDM Mux/Demux present an ideal balance of price and gratifaction for multiplexing and demultiplexing in Metro/Access networks.
