Where can you get the best Mux Demux Modules? I suggest you should come to FiberStore. From 2012 on, FiberStore has came to be the best fiber optic products supplier in China. Our products are all inexpensive with high quality.

As Mux Demux Modules are playing an important role in fiber optic network, more and more areas need these good products. First, let us have a talk about mux/demux. In telecommunications, a multiplexer(or mux) is a device that combines several input information signals into one output signal, which carries several communication channels, by means of some multiplex technique. A demultiplexer(or demux) is, in this context, a device taking a single input signal that carries many channels and separates those over multiple output signals.

What we are going to say today, is the CWDM mux and demux. CWDM is short for coarse wavelength division multiplexing, a technology of WDM. CWDM mux and CWDM demux are designed to multiplex multiple CWDM channels into one or two fibers. The core of CWDM modules application is the passive mux/demux unit. In FiberStore, the common configuration of CWDM modules is 1*4, 1*8, 1*16 channels, available in 19 Rack Mount or LGX module package. Optional wide band port for existing 1310nm or 1550nm port is available to multiplex with these CWDM Channels. Together with CWDM transceiver series or the wavelength converter series, the bandwidth of the fiber can be utilized in a cost effective way. The important advantage of CWDM modules is the cost of the optics which is typically 1/3rd of the cost of the equivalent DWDM optics.

Let us have a look at one of the CWDM mux/demux modules in FiberStore. This is a 8 Channels CWDM module. And here are its Key Features.

1). One rack unit (RU) in height housing-1U
2). Rack mountable in 19 (23 also available on customer requirement)
3). Mux and Demux combined in one 1U Rack
4). Compliant to ITU-T G.694.2 CWDM standard
5). Accepts any data rate and any protocol on any port up to 10 Gbps, 40 Gbps and 100 Gbps
6). Fully transparent at all data rates and protocols from T1 to 40 Gbps
7). Completely passive, no power supply needed
8). Simple to install, requires no configuration or maintenance
9). Low-cost transceivers applicable, existing equipment can still be used
10). ISO 9001 manufacturing facility
11). Lifetime Product Warranty

Note: CWDM mux/demux combine and split light signal of CWDM wavelengths. CWDM transceivers generate light signals of specific CWDM wavelengths. OEO converts two independent signals into a corresponding wavelength in CWDM and DWDM network infrastructures. In addition, the integrated 3R functionality enables to accomplish a transmission of long distances up to 80km. If CWDM transceivers can plug into active devices directly, No need OEO converters.

Welcome to FiberStore and we will offer you the best fiber optic products which are all in good performance.

FiberStore supply two kinds of WDM Equipment, that is DWDM module and CWDM module devices.

DWDM modules inlcude DWDM mux/demux module and DWDM OADM module. As for DWDM mux demux, the everyday configuration is 2CH, 4CH, 8CH, 16 CH, 32CH, 40CH channels. Mux (Multiplexer) products combine several data signals into one for transporting more than a single fiber. Demux (Demulitplexers) separate the signals with the other end. Each signal is in a different wavelength. DWDM Mux/Demux are going to increase a few optical channel technology the transmission capacity perfectly into a single fiber. Right here is the one utilized in the previous fiber optic backbone network bandwidth laser technology. Specifically, we have is close spectral spacing from a specified fiber; multiplexing in addition to a single optical carrier, so that they can benefit from the transmission performance can be accomplished. Like this, because of the information transmission capacity, it could possibly slow up the amount of fiber needed. These channels are employed with the optical Mux together, and then from a single optical fiber transmission on the hub or OTN, where re-use Demux to split up them. These separate channels will be routed to your single node or node group in order to meet the orientation of service requirements of your system. DWDM Mux and Demux provide high-density low-cost solution in this application. You can expect premium quality DWDM Mux/ Demux with some other style, including ABS box, LGX box, 19 inch Rack-mount, customized design. The DWDM Modules combine or split particular wavelengths right single fiber and so are idea for telecommunication and networking. DWDM technology use ITU standard 0.8nm/1.6nm spacing concerning 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.

CWDM modules include CWDM mux/demux module and CWDM OADM module. The more common configuration of CWDM mux/demux module is 2CH, 4CH, 8CH, 16CH, 18CH CWDM mux/demux module. 3 Single fiber or dual fiber connection for CWDM Mux/demux can be purchased. The Coarse Wavelength Division Multiplexing-CWDM Mux/demux really are a flexible plug-and-play network solution, which allows carrier's networks and enterprise companies to cheaply implement point to point or ring based WDM optical networks. CWDM Mux/demux is modular, scalable and it is perfectly appropriate for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks. CWDM modules (Coarse Wave Division Multiplexing) combine or split up to 18 wavelengths to a single fiber. CWDM technology uses ITU standard 20nm spacing between your wavelengths, from 1270nm to 1610nm. CWDM Modules utilize thin-film coating and micro optics package technology. Based on two main configurations: CWDM Multiplexer/Demultiplexer (Mux/Demux) modules and CWDM Add/Drop Multiplexer (OADM) modules. CWDM Mux/Demux Modules come in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 or even more electronics, send on them 1 optical fiber and next de-multiplex the signals into separate, distinct signals for input into electronics along at the opposite end belonging to the fiber optic link.

Above all, you want the type Plastic ABS module cassette, 19 rack mountable box or standard LGX box. Few appear style of connectors, like FC, ST, SC, LC etc, each are positioned on our website, you can mix connector a single device. Buy DWDM modules, CWDM modules and Filter WDM modules on FiberStore with certainty.
