Description: CWDM SYSTEM, Coarse Wavelength Division Multiplexing, as a sort of utilizable short distance WDM transmission system, it has been acknowledged and practiced in Metropolitan Area Network applications. CWDM can be applied to metropolis and Metropolitan Area Network, at the same time it can be applied to City core networks which is great promise in practice. The CWDM is an extension of the Optical Metropolitan Area Network product family. Cable operators and other service providers can utilize the CWDM in outdoor environments to aggregate, over a single fiber pair, multiple private CWDM optical channels originating from multiple customer premises. Operators can also place it in the basement of a multi-tenant building to service multiple end customers with fully private, multi-protocol, optical wavelength services.CWDM can be used in 4/8 in 1 multiplexing fiber-link, replacing equipment attached to optical fiber cable and increasing efficiency of bandwidth with low cost. It is applied to construct Metropolitan Area Network, especially inconvenience in laying fiberleased wirelack of fiber resource and some other operators need increase efficiency of bandwidth. The equipment is exploited by using CWDM technology, multiplexing multi-ray channel whose wavelength interval is 20 nm on one or a pair of fiber to transmission. It can be applied to some occasion ,such as point to pointpoint to multi-pointfast optical multiplexingmovable collocate optical multiplexing. The technology is mature and the cost is low, can reduce the invested capital of building Metropolitan Area Network and extending capacity, so, it is super in competition. The equipment can be applied to service transmission abroad, such as core networkverge networkaccess network in SDHSONETEthernetATM and optical Metropolitan Area Network. Type applicationBe applicable for optical transmission system of any speed from 10Mb/s to 2.5 G b/s Rebuild and upgrade SDHATM and EthernetHigh speed interlink and clear transmission of core networkverge networkaccess network and convergence node in bandwidth optical Metropolitan Area Network  Optical interface indexAttribution Description Transmit center wavelength 1470nm1490nm1510nm 1530nm1550nm1570nm 1590nm 1610nm Channels interval 20nmOptical channel width +/-6nmTemperature excursion ofcenter wavelength..0.080.1nm/ Transmit power. -10dBm +3dBmReceive power... -24dBm -3dBmReceive channel.1270nm 1600nmReceiver LOS alarm power-25dBm-30dBmReceive sensitivity..<-24dBmReceive over loading power..0dBm+6dBmEquipment typeData speed 10Mbps,1.25Gbps and 2.5GbpsMax capacity multiplex 8 double channels on a pair of fibers Multiple working mode 4 way double/single direction convergence, 8 way double convergenceoptical multiplexingTransmission distance 10km20km50km80kmMultiple apply mode point to pointtreechainringInput wavelength 850nm1310nm1550nmFiber single-mode or mult-modeWork temperature and humidity 045,1090%,no frostPower and power waste AC power: 110275V, 5060HZ,DC power: -48V, power waste<70W.
