Product Description:

4Ch CWDM MUX/DEMUX demonstrate low loss and reliable performance. it show broad passbands and high isolation, making them ideal for operation with inexpensive, with uncooled lasers. They feature up to 4 dispersion channels, thereby enabling high capacity, low cost products for the CATV and metro/access markets. For this 4Ch CWDM MUX/DEMUX Can be packed into 1U Rack for easy operation, also can order seperately.

Applications

• Access networks
• Metro WDM systems

Features

• Low insertion loss
