Division technology of the data transmission band solution CWDM (Coarse Wavelength-Division Multiplexing) involves using a multiplexer (MUX) to combine the wavelengths to be carried by more fibers into one that has a de multiplexer (Demux),  at the receiving end of the link, which separates the wavelengths and leads them to different fibers, each ending in separate receivers.

 

Efforts to development and to standardize CWDM systems come in a critical moment in communications for metro-access providers. The need for cheap transportation systems is imperative, so the demand for high bandwidth network is pushed to the limits. Using CWDM, can be added between 2 and 8 wavelengths on the same pair of fiber thus increasing the carrying capacity with minimal investment

The most used CWDM systems are made to operate on eight different wavelengths 1470-1610nm range, but there are MUX / Demux equipments with up to 16 channels in 1290-1610nm range, which, like the previous, are partitioned standard 20nm. The size of these channels avoid wavelength losses and maintain an adjacent gap to that insulation adjacent bands. It was found that certain areas are to be avoided in these intervals, the bands around 1270nm and 1400nm with significant attenuation caused by sensitivity to residual water present in the majority of installed fiber channel and preferential bands due to incompatibility with modules such as the usual optical of 1300nm or 1500 nm. To the extent that these additional losses are controlled over long distances, CWDM overall system performance will be highest.

            The technology CWDM (Coarse Wavelength-Division Multiplexing - WDM GDP) was first used in the early '80s for digital video signal transmission through multimode fiber. Originally Quante Corporation has released a CWDM system partitioned to 800Nm, on four channels that could carry the 140Mb / s each; at first, these systems have been used for cable television. Although it was an advanced solution for dividing and multiplexing of signals by dividing the frequency ranges of wavelengths CWDM system has not produced a significant interest to operators of communications - until now.

.

Module optice CWDM

          

              Meanwhile, CWDM technology has evolved and it was the standardization of wavelengths, in accordance with complementary optical devices (optical fiber SFP modules / GBIC, switches). So, CWDM solution is increasingly becoming an important architecture for data transport.

.

 

         

              CWDM solution uses special lasers that do not require refrigeration - "un cooled lasers - polarized DFB (Distributed-feedback) and optical filters for high bandwidth. Some advantages of this technology are: minimal loss of optical power over long distances, small size and especially the capacity to reduce the cost of additional networking through existing fiber branching. The ability to add between 2 and 8 wavelengths per fiber allows designers to increase without installing more expensive systems, such as DWDM.

.

 

         DWDM Systems (Dense Wavelength-Division Multiplexing - WDM branched) superior in terms of complexity compared to CWDM (whether through a CWDM 8 frequencies can carry up to 8G, instead through a DWDM with the same number of frequency standard can carry 100G - more dense partitioning due to separations of 1.6, 0.8 or 0.4nm). However, commercial availability in CWDM systems is more affordable, offering the benefit of standard wavelengths, making them an excellent alternative for applications in communication networks and protocols for access or metropolitan areas
