Where can you get the best Mux Demux Modules? From 2012 on, Sopto has become to be the best fiber optic products supplier in China. Our products are all inexpensive with high quality.

The utilization of fiber optic cables for communication has opened up gates for communication multiplexing technologies that increase the capabilities at minimum costs.

Wavelength division multiplexing(WDM) is a concept that describes combination of several streams of optical carrier signals (like data/storage/video or voice) on a single physical fiber optic cable by using several different wavelengths

Fiber-optic-based video and audio multiplexers are designed specifically for pro A/V and broadcast applications.

CWDM multiplexer and CWDM Demux are designed to multiplex multiple CWDM channels into one or two fibers. The core of CWDM Module application is the passive MUX DEMUX unit.

Video multiplexers come in a variety of configurations and features that conform to certain quality standards.

In the fiber optic network which uses wavelength division multiplexing (WDM), reconfigurable optical add-drop multiplexer (ROADM) is used to remotely add

Arbitrary choice must be retrieved, adding wavelength, the wavelength can take advantage of the limited resources, the node can be retrieved with the need to do to join the adjustment of the signal wavelength, and has a remote control functions.

In the long-distance optical fiber transmission, the fiber cables have a small effect on the optical signal transmission, the transmission quality of optical fiber transmission system mainly depends on the optical multiplexers’ quality

WDM is a technology that is achieved using a multiplexer to combine wavelengths traveling through different fibers into a single fiber.

Sopot fiber optic video multiplexer adopt the international advanced digital video and optical fiber transmission technology

After languishing for several years as an exciting technology without having a cost-effective application, wavelength division multiplexing (WDM) started playing an important role throughout telecommunications system in the early 1990s.

A fiber optic media converter can be used in any part of the network, for example between routers, servers, switches, and hubs. It is even possible for them to be integrated alongside your workstation.

WDM multiplexer is specialized devices that combine a number of optical streams at distinct wavelengths and launch all their powers in parallel into a single fiber channel.

An optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing systems for multiplexing and routing different channels of light into or out of a single mode fiber (SMF).

Using a WDM (Wavelength Division Multiplexing) to expand the capacity of fiber to carry multiple client interfaces is a very convenient way because the physical fiber optic cabling is not cheap.

General OADM node can use four port model (Figure 1) to represent, includes three basic functions: Drop required wavelength signal, Add rumored signal to other wavelengths pass through unaffected.

As a result of rapid development of data services, network convergence speed accelerated MAN has become a hotspot of network construction

Early FOADMs, with preassigned channels at static nodes, were typically built with thin-film filters (TFFs)
