CWDM system is able to provide optical networking support for high-speed data communication for metropolitan area networks (MANs). And in some previous articles, I have talked a lot about CWDM, such as the components used in CWDM system. In this article, I’d like to have an introduction to CWDM system installation and connection. Procedures for […]

Introduction to the Components Used in CWDM System
CWDM system is a passive optical solution for increasing the flexibility and capacity of existing fiber lines in high-speed networks. It increases fiber capacity by placing widely spaced, separate wavelengths (between 1310 nm and 1610 nm) from multiple ports onto a single-mode fiber pair on the network. The CWDM system components are passive and require […]
Current Situation of the Development of CWDM
In order to research the present situation and the existing problems about CEDM technology, Fiberstore invited some equipment manufacturers include Huawei, Shanghai bell alcatel(asb), CIENA, light bridge, Fire network to test CWDM equipments. Main test content includes: Main optical channel MPI interface, OTU testing, business interface testing (including SDH, Ethernet, transparent rate channel interface, ESCON, […]
Multiplex Your Fiber by Using CWDM or DWDM
Using a WDM(Wavelength Division Multiplexing) for expanding the capacity of the fiber to carry multiple client interfaces is a highly advisable way as the physical fiber optic cabling is not cheap. As WDM widely used you must not unfamiliar with it, it is a technology that combines several streams of data/storage/video or voice protocols on the […]
CWDM Optical Add-Drop Multiplexing Technology
It is more and more instancy to develop All Optical Network（AON）as the progress in area of communication technology. The technology of optical add drop multiplexing（OADM）is one of the key technologies to implement AON. CWDM OADM can provide multiplex and demultiplexing or the ability to add-drop multiple fibers to one. Different styles of OADM OADM (CWDM-MUX-AD-xxxx=):The […]
