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 […]
CWDM OADM
Construct smarter fiber optic networks with ROADM technology
As IPTV, triple play, VoIP and other new telecommunications services rise, people find that IP-bearing agreement business has rapidly spread in most regions of telecommunications and fiber optic networks. IP-based packet-based carrier network transformation has been become an irreversible trend. In this trend, carriers are shifting the entire network infrastructure, business anticipates the integration of […]
Optical add-drop multiplexer Wikipedia
An optical add-drop multiplexer (OADM) is a device used in wavelength-division multiplexing systems for multiplexing and routing different channels of light into or out of a single mode fiber (SMF). This is a type of optical node, which is generally used for the construction of optical telecommunications networks. “Add” and “drop” here refer to 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 […]
