Choose Mux Demux Modules From FiberStore

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

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.

Reach learn about Coarse WDM

Coarse WDM is exactly what a CWDM means. Originally, the concept of a "coarse wavelength division multiplexing" was fairly generic, and meant a variety of things. On the whole, these tips shared the possibility that deciding on a channel spacings and frequency stability was approaches erbium doped fiber amplifiers (EDFAs) cannot be utilized. Ahead of the relatively ITU standardization in the term, one common meaning for coarse WDM meant two (or possibly more) signals multiplexed onto 1 fiber, where one signal was in the 1550 nm band, and also other inside the 1310 nm band.

The main manifestation of the latest ITU CWDM standard is that the signals will not be spaced appropriately for amplification by EDFAs. This therefore limits the overall CWDM optical span to somewhere near 60 km to have a 2.5 Gbit/s signal, that is certainly made for easy use in metropolitan applications. The relaxed optical frequency stabilization requirements give the associated costs of CWDM to approach that surrounding non-WDM optical components.

CWDM is also being employed in cable networks, where different wavelengths are used for the downstream and upstream signals. Through these systems, the wavelengths used tend to be widely separated, for example, the downstream signal could be at 1310 nm as the upstream signal has reached 1550 nm. An intriguing and relatively recent development relating coarse WDM is a the origin of GBIC and small form factor pluggable (SFP) transceivers utilizing standardized CWDM wavelengths. GBIC and SFP optics provide for something not far from a seamless upgrade in even legacy systems that support SFP interfaces. Thus, a legacy switch system can be simply "converted" permitting wavelength multiplexed transport on the fiber by judicious pick of transceiver wavelengths, merged with an economical passive optical multiplexing device.

The main CWDM merchandise is CWDM modules which feature CWDM mux/demux module and CWDM OADM module. The most popular configuration of CWDM mux/demux module is 2CH, 4CH, 8CH, 16CH, 18CH CWDM mux/demux module. For DWDM mux/demux, the regular configuration is 2CH, 4CH, 8CH, 16 CH, 32CH, 40CH channels. One example is, a CWDM Mux/demux 4ch module signifies that it really is in the configuration of 4CH channels. 3 Single fiber or dual fiber connection for CWDM Mux/demux are accessible. Based on the form of Plastic ABS module cassette, 19?¡¥?¡¥ rack mountable box or standard LGX box. With no challenege show up types of connectors, like FC, ST, SC, LC etc, each one is on our website, therefore we are able to mix connector on one device. CWDM Mux/Demux module- CWDM MUX and CWDM Demux are designed to multiplex multiple CWDM channels into 1-2 fibers. The core of CWDM Module application will be the passive MUX/DEMUX unit. The everyday configuration is 1x4, 1x8, 1x16 channels. Optional wide band port for existing 1310nm or 1550nm port is available to multiplex basic CWDM Channels. As well as our CWDM Transceiver series or perhaps the wavelength converter series, the bandwidth within the fiber may be used in any cost effective way.

Like the CWDM, an OADM is another device applied to WDM systems for multiplexing and routing different channels of fiber into or beyond one mode fiber (SMF). DWDM OADM is built to optically add/drop one or multiple DWDM channels into a couple fibers. Exactly like CWDM, DWDM OADM modules include the main products of your system. As an example, DWDM 1 channel OADM module is often a DWDM OADM module in the configuration of a channel.

Whether your network has a few cores of fiber, redundant network, ring or linear network design etc, Fiberstore typically offer different types of CWDM modules as well as OADM configurations to tailor fit your network architect.
