VOA-MUX/DMUX Modules
VOA-MUX/DMUX (VMUX) Modules are passive modules for
multiplexing and demultiplexing up to eight bands or 100 GHz
channels with integrated power equalization. VMUX modules
independently equalize power levels in each channel or band
using DiCon's MEMS Attenuator (VOA) and integrated (PIN)
photodiodes. VMUXes are a low cost alternative to external
Dynamic Gain Equalizers.

Multi-Channel MUX/DMUX with power monitoring and level control
Upgradeable in groups of 4 bands or 100 GHz channels
Ideal for metro and long haul applications
Optional upgrade ports
Applications
VMUX Modules are ideally suited for all MUX applications which
require per band or per channel power equalization. For MUX
applications, they provide pre-emphasis after terminal equipment
transmitters. For DMUX applications they provide optical level
automatic gain control in front of terminal equipment receivers.
VMUX Modules can also be used to equalize the Add side of
OADMs.
