Description
Low Band CWDM 4 Channels Mux Demux
1270-1330nm, Dual Fiber, Plug-in Module
This is a 4-channel low-band 1270nm to 1330nm CWDM multiplexer for 400G 4-wavelength transceivers. It can be used for 400G to 4x 100G breakout configurations and can also be used to aggregate 4x 100G channels.
High Band CWDM 4 Channels Mux Demux, 1470/1490/1590/1610nm with Expansion Port
High band 4CH CWDM with upgrade port. The 4 wavelength ports use 1470nm, 1490nm, 1590nm and 1610nm high band channels. The bandwidth of the upgrade port is 1260nm to 1625nm.
The upgrade port on the 4 channel CWDM can be used to join additional CWDM channels for future network expansion, for example, adding a low band 8 Channel CWDM 1270nm to 1450nm water peak skipping version or 1290nm to 1430nm version. It can also be connected to a fiber network carrying legacy 1310nm. But most operators will use this port to merge DWDM channels in some cases.
