By Increasing Demands For Broadband Services Now Many Customers have Fiber Lack Between Telecom Stations.Also By New XWDM Systems we Can Reach to About 480GB/S Banwidth on one Core Fiber Instead of Using that For Low Bandwidth Conections.CWDM Devices Divided to Passive and Active Systems.We use Active Systems When Customer Systems Can not Accept SFP/XFP/CFP Modules that They Can Provide Valid CWDM Wavelenghes.But Now Many Systems Support This Type Modules and if There is A system That it Can Not Support That Modules (Like FIX Optical Ports) Then we Can use Desktop Trsnsponder For it.Passive CWDM Systems do not have any PWR unit or Active unit and They are Totally Includes Passive Components.So Customers Can be Sure that Their Trafic will not Interupt in any Cases.In CWDM Passive Systems we have a Chassis with 1 U Height and 4 Slotes.Each Slot Can Accept one Trfic Card From Follow Items.Pls Note Each Mux Card Needs one Demux Card Also.So For Example For one 8CH Dual Fiber System we Need one Chassis and one MUX Card and one Demux Card on Same Wavelenghes.

 

 

 

Model:PED-8CH-CWDM

This Module Can Accepts 8 Valid CWDM Wavelengths And Multiplex Them to  one Fiber or Demultiplex Recive CWDM Single to 8 Valid CWDM Wavelenghts.one 8ch System Needs one MUX Card and one DEMUX Card on Each Device.Also MUX and DEMUX Cards Can use one Fiber and in This Case The Conection Named Single Fiber But Wavelengthes in Both Sides Must Be Different (Each channel uses 2 wavelengthes).This Module Can be 4 ch with Customer Order.

 

 

 

Model:PED-16CH-CWDM

This Module Can Accepts 16 Valid CWDM Wavelengths And Multiplex Them to  one Fiber or Demultiplex Recive CWDM Single to 16 Valid CWDM Wavelenghts.one 16ch System Needs one MUX Card and one DEMUX Card on Each Device.Also MUX and DEMUX Cards Can use one Fiber and in This Case The Conection Named Single Fiber But Wavelengthes in Both Sides Must Be Different (Each channel uses 2 wavelengthes).This Module Can be 18 ch with Customer Order.(Picture is For 16ch/8Service Signle Fiber Module)

 

 

 

Model:PED-OADM-CWDM

in Many CWDM Applications we Need to Add/Drop wavelengthes in Telecom Stations in Path of Optical Fiber.This Module Allow us to Add/Drop 1 to 4 wavelengthes in Our Applications.in The Other word This Module Filter our Need wavelength From Main Optical Signle and Drop it and Can Add Another Wavelength instead of that to Main Signal.
