The H-MD-3155 is a 1310/1550nm band Mux/Demux unit. The H-MD-3155 band filter is intended for cases where a legacy 1310nm channel is to be combined with CWDM channels in the upper CWDM band (1460 nm - 1630 nm) or DWDM channels.
The 1310nm port covers 1265.5-1350nm which also includes the low band CWDM channels 1271-1331nm. This port can thus be used for e.g. 100G CWDM4-MSA channels, enabling a 100G channel to be carried as an alternative via this port.
The H-MD-3155 is to be fitted in the H-Series 1RU chassis H-CHASSI-1RU.
