Something you should know about CWDM DWDM and OADM
CWDM/DWDM Mux/Demux and OADM are all fit in with Passive. CWDM and DWDM technology produce an efficient strategy to share one set of fiber strands and hang together various communications interfaces, simply by using different wavelengths of light for each channel. Thus they could expand the proportions from the network without laying more fiber. And that i want to introduce the actual basical description of CWDM Mux/Demux, DWDM Mux/Demux and OADM.
As you know, Mux (Multiplexer) products combine several data signals into one for transporting over the single fiber. Demux (Demulitplexer) separates the signals at the opposite end. Each signal are at an alternative 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 suitable for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks. CWDM tools are widely used in less precision optics and lower cost, un-cooled lasers with lower maintenance requirements. Weighed against DWDM and Conventional WDM, CWDM is a bit more affordable and much less power usage 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 excessively electronic products, send on them somebody optical fiber and de-multiplex the signals into separate, distinct signals for input into gadgets along the opposite end for your fiber optic link.
DWDM Mux/Demux
The Dense Wavelength Division Multiplexing-DWDM Mux/Demux Modules are built to multiplex multiple DWDM channels into 1 or 2 fibers. Depending on type CWDM Mux/Demux unit, with optional expansion, can transmit and receive around 4, 8, 16 or 32 connections of standards, data rates or protocols more than one single fiber optic link without disturbing the other person. DWDM MUX/DEMUX modules provides best and low-cost bandwidth upgrade on your current fiber optic communication networks.
OADM
OADM(Optical Add-Drop Multiplexer) is often a device utilized in WDM systems for multiplexing and routing different channels of fiber into or out of a single mode fiber (SMF). OADM is made to optically add/drop one or multiple CWDM/DWDM channels into one or two fibers, provides capacity to add or drop an individual wavelength or multi-wavelengths from the fully multiplexed optical signal. This enables 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 continue on in direction of the remote site. Additional selected wavelengths can be added or came by successive OADMS if required.
Several common Kinds Of CWDM Moudules
Coarse Wavelength Divison Multiplexer/Demultiplexer Module (CWDM Mux/Demux) is really a flexible, low-cost solution that effective at combining nine optical signals in to a fiber pair. The CWDM Mux/Demux is designed to interoperate with the WaveReady distinct transponder and optical regenerator solutions as well as CWDM transponders and small form-factor pluggables (SFPs) utilized in acquireable transmission equipment.
Common utilizations of CWDM technology include the multiplexers and de-multiplexers or optical amplifiers to improve the ability in the fiber optic cable. The CWDM Mux/Demux modules including CWDM MUX and CWDM Demux, are designed to multiplex multiple CWDM channels into 1 or 2 fibers. As well as highly reliable passive optics certified for environmentally hardened applications, the CWDM Mux/Demux lets operators use available fiber bandwidth in local loop and enterprise architectures.
In accordance with the wavelength or running channels in the each signal, CWDM MUX/DEMUX includes 4CH, 5CH, 8CH, 9CH, 16CH, 18CH CWDM Mux/Demux. These CWDM MUX/DEMUX can be found in 19″ Rack Mount or LGX module package.

CWDM supplies the most economic and efficient wavelength division multiplexing solutions for metro edge and access networks.DK Photonics CWDM products cover 2 channel, 4 channel, 5 channel, 8 channel, 9 channel, 16 channel and 18 channel CWDM Mux/Demux.DK Photonics Technology offers CWDM OADMs (Optical Add/Drop Module) from 1 to 16 channels for CWDM networks, including 1 channel, 2 channel, 4 channel, 8 channel and 16 channel CWDM OADM.
The CWDM OADMs are passive devices that can multiplex/demultiplex or add/drop wavelengths from multiple fibers onto one optical fiber. Through the use of CWDM technology, individual channels might be optically added or dropped from a fiber pair while allowing pass-through visitors to continue unobstructed through the bus or ring. It offers low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.
