BIDI transceivers cannot be use with single-fiber bidirectional MUX DEMUX together directly, but they can be converted into WDM transceivers that have corresponding wavelengths by OEO to transport business. By FS on 05/08/2018

When CWDM MUX A has five channels with EXP port, you can connect MUX B via express port. These wavelengths are other 13 wavelengths. In the same way to DWDM MUX DEMUX. By FS on 04/17/2018

Yes. Fiber diameter ( 2.0mm, 0.9mm, 3.0mm ), pigtail length ( 0.25~2m, no extra charge ), with/without connectors, and ABS size (141*115*18mm, 120*80*18mm, 100*80*10mm) need to be considered. By FS on 09/28/2017

Yes, we can customize your Mux perfectly tailored to your specific needs. Any wavelength, any connector, any housing and any special ports can be achieved. By FS on 08/10/2017

Traditional G.652 optical fiber has obvious water peak in the general regions of 1380nm, which means avoiding 1390nm-1430nm CWDM channels, like items #42937. But Zero Water Peak Fiber (ZWPF) ITU-G. 652.D and ITU-G G.657.A1 resolves water peak issues. By FS on 05/10/2017

Single fiber Mux/Demux are always used in pairs (example: #50116 used with #50117). The transmit wavelength of the client port at side-A must match the receive wavelength of the same client port at side-B. As for the wavelength of the transceiver, it is mainly based on the transmit wavelength of the client port. By FS on 06/30/2017
