Coarse Wave Division Multiplexing (CWDM) is a technology which multiplexes a number of optical signals onto a single fiber by using different wavelengths of light. The CWDM Multiplexer Mux Demux support ITU-T G.694.2 wavelengths between 1270nm to 1610nm in 20nm increments. The CWDM modules are available in 4 to 16-Channel (wavelength) models, supporting a variety of wavelength combinations and port configurations. UnitekFiber offers a wide selection of CWDM, which allow for lower networking cost, lower complexity, and enhance fiber optic systems.
CWDM Mux Demux is an optical device that combines multiple optical signals of different wavelengths onto a single fiber for transmission and separates them at the receiving end. CWDM Mux Demux is a passive device and does not require an external power supply. Therefore, CWDM is more cost-effective, requires less complex equipment, and is able to achieve longer transmission distances. CWDM can be deployed on most types of fiber networks. It is usually deployed in enterprise networks and telecommunication access networks, fiber networks, and data centers in a point-to-point topology.
The most important advantage of CWDM Demux/Mux Multiplexer is low equipment cost, and it could reduce network operating costs. Due to the small size of the CWDM Demux/Mux, low power consumption, easy maintenance and convenient power supply, 220V AC power can be used. Due to its small number of wavelengths, the board backup volume is small. 8-wavelength CWDM Demux/Mux has no special requirements for optical fibers. G652, G653, and G655 optical fibers can be used, and existing fiber optic cables can be used. CWDM system can significantly increase the transmission capacity of optical fiber and improve the utilization of optical fiber resources. The construction of metropolitan area networks is facing a certain degree of tightness in optical fiber resources or expensive prices for leasing optical fibers. At present, a typical CWDM system can provide 8 optical channels, and according to ITU-T G694.2 specifications, it can reach up to 18-channels.
CWDM multiplexer is widely used in cable TV networks and transceivers like GBIC and SFP CWDM optics, providing standardized wavelengths for efficient data transmission. Passive CWDM, ideal for FTTP, requires no power and uses passive optical components. Overall, CWDM supports cost-effective transmission of data, video, and voice signals. The CWDM Mux Demux offers flexibility with various wavelength combinations ranging from 1270 nm to 1610 nm, with 20nm spacing. Depending on the specific application, the CWDM Mux Demux can be configured into different channels. When deploying a CWDM multiplexer in your network, it is essential to pair it with a CWDM demultiplexer at the opposite end. This allows for the separation or demultiplexing of wavelengths, ensuring they are directed to the correct receivers. Typically, a CWDM Mux Demux serves as a multiplexer or demultiplexer at either end of the fiber cable span, and always needs to be used in pairs.
