MDU8-D

The function of the MDU16-D is to add and drop 16 DWDM channels with 100GHz spacing. One card supports multiplexing of 16 wavelengths in the transmit direction and de-multiplexing of 16 wavelengths in receive direction.

Upgrade/Express port is provided so that two MDU16-D cards can be cascaded to build a 32 channel system with 100GHz spacing.
