18CH MUX operating temperature range is -40 ° C ~ +85 ° C, 125℉=52℃, so Mux can work properly. By FS on 10/28/2018

The monitor port on the CWDM MUX uses an optical splitter to monitor the power of multiplexed signal. The split ratio can be customized and the default split ratio is 1%. The port cannot serve as a live fiber test port. By FS on 10/24/2018

The band indicator bar of FS CWDM Mux front panel is colorful, and the entire panel is black. By FS on 09/15/2018

Thanks for your question. This item belongs to passsive product, which is only selective for wavelengths. It will not affect the transmission of jumbo frames as long as the wavelengths match. For further question, welcome to contact with Sales@fs.com freely. By FS on 08/08/2018

You can choose C53-C60 DWDM MUX connects CWDM MUX 1530nm port or C30-C37 DWDM MUX connects CWDM MUX 1550nm port. By FS on 04/27/2018

Only Monitor port is available. Because the full channels of CWDM MUX DEMUX are 18 wavelengths. Execept Monitor port, no other special services can be added. By FS on 01/30/2018

Yes, since 1310 port can transport the adjacent +/-40nm wavelengths signals, you can use 1270nm-TX/1330nm-RX & 1330nm-RX/1270nm-TX BIDI module on 1310nm port of CWDM MUX DEMUX. By FS on 01/30/2018

Yes, if 1550nm port connects 1550nm optical transceiver, please skip these five wavelengths (1510nm, 1530nm, 1550nm, 1570nm and 1590nm) when choose the channels of CWDM MUX DEMUX. In the same way for 1310nm, please skip 1270nm, 1290nm, 1310nm, 1330nm and 1350nm. By FS on 01/30/2018

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 08/11/2017

This could be achieved by connecting the 1530nm or 1550nm CWDM channel to the line port of DWDM Mux Demux. CWDM 1530nm matches to narrowband C52-C61 of DWDM, CWDM 1550nm matches to narrowband C30-C37 of DWDM. By FS on 06/08/2017
