Tunneling of Ethernet
Two of the fiber ports can tunnel Ethernet between two XRT boards when equipped with appropriate SFP modules. More ports can be configured on request. The data rate can be up to 1,000 megabit/s.
Independent routing matrix of 8,448 x 8,448 inputs and outputs
The routing capacity has been designed in such a way that all channels of the fiber optic connections and those of the base unit can be included.
Automatic propagation delay compensation for very long fiber optic connections
In a NEXUS network, large differences in the distances of the fiber optic connections can occur, among other things, so that the latency that occurs is detected and compensated for by analyzing the word clock phase position.
6 high-speed ports for the transmission of 2,048 audio channels
Half of the available fiber ports are designed as high-speed versions and can transmit up to 2048 channels. Together with the routing function, this makes it possible to chain the base devices according to the daisy-chain principle.
Sample-accurate switching in case of failure of redundant connections
In both port-based redundancy and card redundancy, signal switching is not audible and can only be detected by a message in the operating software.
Exchangeable standard SFP modules
The ports of the XRT card can be equipped with interchangeable SFP fiber optic modules to meet different applications. The modules can be included in the delivery or fitted by the user. Multimodemodemodules are used as standard, which allow a transmission with a range of 500m. Alternatively, single-modem modules with a range of up to 100Km can also be used.
Redundant configuration of ports possible
If two basic devices are connected redundantly, the signals are sent over both lines, so that in the event of an accident the signals can be switched over with sample accuracy and without crackling.
Optionally activatable re-routing in case of failure of non-redundant connections
When optical rerouting is enabled and a fiber optic connection fails or is disconnected, the board automatically searches for another route to the destination. This happens with an interruption of the data stream.
Support of any network topologies
The network topologies are freely selectable and, for example, a circular or star-shaped connection structure can be set up.
