The T&S CWDM OADM (Optical Add-Drop Multiplexer) module is based on wavelength division multiplexing (WDM) technology utilizing thin film filter (TFF) technology. This module offers a wide range of package sizes and wavelength options to suit various network requirements. In the optical transmission path, the OADM enables the addition or removal of specific WDM signals without the need for photoelectric conversion, making it a crucial element in WDM optical networks. By incorporating the OADM into a network, operators can enhance flexibility, simplify upgrades, and easily scale their systems. This versatility makes the T&S CWDM OADM module an ideal solution for applications in LAN, MAN, and other optical communication fields.
