CWDM are based on thin film filter technology,used for network expansion,suitable for 4G and 5G network.Especially for 5G Fronthaul AAU/BBU widely with 10G,25G or other type optical transceiver. UNIFIBER provide up to 18Ch module,achieve bidirectional MUX/DEMUX over single fiber.
Under 18Ch CWDM,available with UPG port.Up to 18Ch will be w/o UPG port.All types of number channel can support Monitor port,1% or 2% optional.In generally,WDM module,LGX and Rack Mount(Chassis) all have three types about MUX DEMUX:
1.MUX-from the first channel to the final channel-insertion loss from low to high
2.DEMUX-from the first channel to the final channel-insertion loss from high to low
3.MUX/DEMUX in one-MUX part from the first channel to final channel-insertion loss from low to high,DEMUX part from the first channel to final channel-insertion loss from high to low
