Description
Overview
GAOTek fiber optic DWDM module is based on PLC technology. Compared with traditional TFF film filter, It has the advantages of high integration, good uniformity, low PWD, small insertion loss and so on due to the multi-channel characteristics of DWDM module, it is widely used in man, backbone network and data center for equal long-distance signal transmission.
