The T&S TFF 200GHz DWDM OADM Module (Optical Add-Drop Multiplexer) is a critical component for flexible and efficient wavelength routing in Dense Wavelength Division Multiplexing (DWDM) networks. Featuring 200GHz channel spacing, this OADM module allows selective addition or subtraction of optical wavelengths, enabling dynamic network reconfiguration without disrupting the entire system. It provides high isolation, low insertion loss, and excellent channel performance, making it an essential solution for modern telecom and data center applications.
