Networking

NEXUS Base Devices are networked using XFOC fibre-optic interface boards and duplex fibre-optic cables. This approach allows a variety of network setups to be implemented, for example, a star-topology net with parallel and redundant fibre-optic lines between Base Devices.
The Base Device network is an entity. All inputs, outputs, and processing channels can be accessed and operated from anywhere on the routing system. In the GUI, a single crosspoint simply connects an input to an output — it is up to the system to establish the shortest available connection on the Base Device network.

Optical Lines

The optical lines between Base Devices are always in duplex mode. Line capacity is 256 audio channels plus communications and sync data. The number of audio channels transferred in each direction can vary. Possible combinations are 128 audio channels per direction or 192/64 respectively 64/192 audio channels.
Fibre-optic cables are also convenient in mobile applications: Despite their immense transmission capacity, they are thin and light-weight. The galvanic separation established by optical lines avoids ground loops between Base Devices and increases electrical secu-rity. Fibre-optic cables can span several thousand metres without quality degradation and are insusceptible to electromagnetic and electrostatic interference. Therefore, new fibre-optic cables can be run in existing cable ways with no need for shielding.
