Buy Cost Effective CWDM Fiber Optic Products

Posted on by FS.COM

The use of fiber optic cables for communication has exposed gates for communication multiplexing technologies that maximize the capabilities at minimum costs. CWDM(Coarse wavelength division multiplexing), modulates different wavelength lasers with multiple signals. In effect, what this means is maximized use of a single optical fiber to deliver and receive a many signals, minimizing costs for telecom companies. Companies simply use the best optical amplifiers, multiplexers and demultiplexers to boost capacity from the fiber optic using CWDM technology.

Related technologies are DWDM(dense wavelength division multiplexing) and conventional WDM. Conventional WDM make use of the 3rd transmission window with a wavelength of 1550nm, accommodating as much as 8 channels. DWDM is identical but with a higher density channel. Systems could use 40 channels, each at 100 GHz spacing or 80 channels spaced 50 GHz apart. A technology, the ultra dense WDM is capable of working at a spacing of just 12.5 GHz, allowing more channels. DWDM and WDM are expensive in contrast to CWDM.

In CWDM technology, there is an increase in channel space. This means requirement of less sophisticated and cheaper transceiver devices. Operating in the same window of 1550 nm and using OH-free silica fibers, maximum efficiencies are achieved in channels 31, 49, 51, 53, 55, 57, 59 and 61. The channels are spaced 20 nm apart. DWDM spaces them 0.4 nm apart. Less precision optics minimizing cost, uncooled lasers with lower maintenance requirements can therefore be utilized in CWDM devices, operating in the region of 1470, 1490, 1510, 1530, 1550, 1570, 1590 and 1660nm. 18 different channels can be used with wavelengths as much as 1270 nm. In addition to being cost effective, power consumption for laser devices utilized in CWDM technologies are also far less. CWDM signals can not be transmitted long term but they are ideal for applications inside a selection of 60 km for example inside a city as well as for CATV(cable tv) networks allowing upstream and downstream signals.

A quantity of manufacturers offer all related CWDM multiplexers, demultiplexers and optical amplifiers. Networking solution providers are the right people to seek guidance for use of CWDM, DWDM or WDM technology. They carry out the entire installation and commissioning from the right, integrated devices for error-free high-speed, high data transmissions over fiber optic lines. Cost and gratifaction optimized CWDM solutions with built in expansion capabilities can be found from reliable and trusted online network solution companies.
