OADM Card High Integration DWDM Transmission MUX DEMUX System
OADM card is based on OSP platform, used for DWDM transmission system, worked as an optical add-drop multiplexer. OAD4D-C21 board can be used for OADM site, it can add or drop the wave of C21 ~ C24, while maintain the transmission of other wavelengths. OAD8D-C21 board can be used for OADM site, support add or drop from C21 to C28, meanwhile maintain the transmission of other C-band wavelengths. OAD16D-C21 board can be used for OADM site, work as optical add-drop multiplexer, support add or drop from C21 to C36, meanwhile maintain the transmission of other C-band wavelengths. The card is a passive board, built-in the OADM module based on TFF technology. It can support network management and management.
