Hilink CWDM (Coarse Wavelength Division Multiplexing

The CWDM passive optical system provides widely optical networking support for high-speed data communication of metropolitan area networks (MANs) over a grid of 18 CWDM optical wavelengths in both ring or point-to-point configurations,1270nm~1610nm

Please connect your multiplexed/demultiplexed MUX/DEMUX wavelengths and add/dropp(oadm) channels to CWDM SFP XFP,which installed in your network switches.

The 18ch CWDM channels by  

1270nm,1290nm,1310nm,1330nm,1350nm,1370nm,
1390nm,1410nm,1430nm,1450nm,1470nm,1490nm,
1510nm,1530nm,1550nm,1570nm,1590nm,1610nm

A. Single Fiber CWDM Mux/demux with CWDM optics SFP XFP


B. Dual Fibers duplex CWDM Mux/demux  with CWDM SFP 

C. CWDM Mux/demux with OADM system

The most important advantages of hilink CWDM system is the high quality components with low insertion loss. 


Advantage 1

CWDM systems can make high optical fiber transmission capacity, improve the utilization of the resources of optical fiber. with CWDM SFP. 


Advantage 2

Another advantage of CWDM is small volume, compact, low power consumption.


Advantage 3

Compare with the tranditional TDM, CWDM has better rate and agreement transparency.


Advantage 4

CWDM has the very good flexibility and expansibility with Express , UPG port,FWDM CATVE.


Advantage 5

The use of CWDM system can improve business quality

Hilink CWDM system was highly valued by the industry due to the above advantages. In the while, it is be widely used of Telecommunications, broadcasting and CATV, enterprise nets, campus network and other field. But there is also some disadvantages, such as less light channel, function of equipment are not perfect and so on. With the development of technology and the expansion of the market, located in intracity networks connect into layer optics CWDM technology can have a good application in prospect.

DWDM with CWDM  the WDM networking deliverys the excellent solution for long haul transfer in networking.
