GAOTek-MDS-147

Description

Overview

GAOTek dual fiber CWDM mux demux the optical signals of different ITU-T WDM wavelengths are multiplexed onto a single optical fiber for transmission. At the receiving end, the mixed signals in the optical fibers are decomposed into signals of different ITU-T WDM wavelengths and are connected to corresponding receiving devices. This product is a multilayer dielectric film type wavelength division multiplexer, which has the characteristics of mature technology, low insertion loss, and can be widely used in CWDM or DWDM networks.
