We are a supplier for the H-MD-C05, a 4ch CWDM Mux/Demux unit that comes with an Extension port. The H-MD-C05's four wavelength ports function on the high CWDM band channels, specifically 1471/1491nm & 1591/1611nm. The wavelength band that lies between these can be employed for DWDM channels through the Extension port.
Alternatively, the Extension port of the H-MD-C05 can be utilized to incorporate 8 channels in the low CWDM band or for traditional 1310nm services. As a distributor, we ensure that all product specifications and attributes remain accurate and unchanged.
