Now, here let us show you interesting scheme, how we can multiplex 4 or more 1310 nm based Gigabit Ethernet channels, over same fiber pair using these CWDM multiplexers. As you can see in video, first we use our Gigabit Media Converter, and then by means of SFP-SFP fiber converter, we convert 1310 nm to CWDM 1490 nm wavelength, which then goes injected further in CWDM multiplexer. In above example it’s 4 channel CWDM mux, but ordering options are 8 or 16 channels.

Description
AN-PA-CWDM is the use of several layers of different dielectric thin films are combined to form an interference filter having a specific wavelength selection characteristics, and can achieve separation of different wavelengths or in combination
AN-PA-CWDM the product uses 1U rack design, can be installed in a standard 19-inch rack can support 20nm apart between 1270nm ~ 1610nm CWDM wavelength multiplexing and demultiplexing , and have upgraded features.
