100 GHz DWDM Optical Add-Drop Multiplexer
Pictures and Schematic Diagram
The dense wavelength division multiplexer, or DWDM for short, is made with patented technology that enables an eco-friendly multiplexing and routing process which does not involve any heat production or changes in fiber temperature. It is a popular style of optical add drop multiplexer.
This passive optical component offers ultra low insertion loss, superb thermal stability, and unparalleled reliability. Housed in a lead-free packaging, the DWDM optical add drop multiplexer does not contain any epoxy along its optical path. Built strictly to Telcordia GR-1221 and GR-1209 standards, XINSHENG DWDM is the fiber optic components of choice for wavelengths management and efficient data transmission.
