No, the channel bandwidth of CWDM Mux Demux is ±6.5nm, while the QSFP28-DR-100G transceiver has four central wavelengths, which requires the CWDM Mux Demux with a 1310nm special port for transmission. But this 18ch CWDM Mux Demux can't add the 1310nm special port , since it has the 1310nm wavelength itself. Par C***n le 28/05/2020

CWDM Mux Demux is passive and has nothing to do with the transmission distance of the system. The transmission distance depends on the performance of the sending and receiving devices in the system. Par G***i le 01/04/2020

18CH MUX operating temperature range is -40 ° C ~ +85 ° C, 125℉=52℃, so Mux can work properly. Par D***s le 28/10/2018

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. Par G***a le 24/10/2018

The band indicator bar of FS CWDM Mux front panel is colorful, and the entire panel is black. Par S***a le 15/09/2018

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. Par I***o le 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. Par L***a le 27/04/2018

Only the monitor port is available, the expansion and 1310nm port can not be added since 18CH CWDM Mux Dwmux covers the full channels of CWDM Mux Demux, the expansion port is not required. And if the Mux Demux has 1310nm special port, it cannot use the wavelength of 1270-1370nm, so the 1310nm port can't be added on 18CH CWDM Mux Demux. Par C***e le 30/01/2018

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. Par A***n le 30/01/2018

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. Par A***n le 30/01/2018
