Continuum DVP eXtra Dense QAM Array 24 Housing
The XDQA24 housing is a compact, modular 1RU high 19-inch housing provided
with a system controller/input board, which controls the Quad Channel QAM Cards
in the housing. This system controller/input board is equipped with an integrated
network interface for system management and control. This board is provided with 2
Gigabit Ethernet (GbE) ports (electrical or optical SFP type modules).
The fans mounted at the back of the device and in the PSU modules create an optimal
airflow inside the housing by which the XDQA24 system does not require an open
rack space above nor underneath.
