Product Description

CWDM  Mux/Demux  19 inch Rack with 2 LGX box of Dual fiber with Upgrade Port 1470-1610nm G.657.A1 LC/UPC

Product Description

The CWDM Mux/Demux covers all channels from 1270nm to 1610nm in 20nm increments. It is a flexible network solution that allows network operators to cost effectively implement point to point or ring based WDM optical networks.

Mux/Demux can increase your network capacity combined with SOPTO Multiservice Transport Device (Such as EDFA, DCM, OEO and so on), which can improve the manageability and interconnectivity of WDM Network.
