In the fiber optic network which uses wavelength division multiplexing (WDM), reconfigurable optical add-drop multiplexer (ROADM) is used to remotely add, block, pass or redirect modulated light emissions-infrared and visible-within a range of wavelengths. With ROADM devices, signal switching doesn’t need optical-to-electric and electric-to-optical conversions. Instead, outgoing light beams can be generated, incoming beams could […]

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 […]
