Stageboxes & Fibre Links
The C-SB Stagebox utilises fibre-optic cable for audio connection between itself and the Centuri Processor.This provides
the advantages of noise immunity, reduced weight and bulk of wiring and the elimination of earth loops.A separate control
signal (for gain, pad, filter switching etc.) is carried over the SSL ethernet network.This control signal can be converted into
fibre for runs longer than 100m.
The standard connectors for the fibre links are duplex SC at both the Centuri and the Stagebox ends.A 2m lead is provided
as standard with each stagebox.
When Stageboxes are specified, it is recommended that a 10/100 ethernet hub/switch is installed so as to provide isolation
for the remote network connection(s).A 1U rack mounting 16-port switch is available as a cost option.
Longer fibre cables and/or ruggedised OB cable using adaptor panels/patch panels are options. SSL is able to provide a
range of fibre solutions although the facility may prefer to provide its own fibre installation. Details of fibre installation
options should be discussed with SSL’s Project Engineering Department prior to the time of order.
For location of Stageboxes at distances of greater than 100m from the Centuri rack the ethernet control cable will have
to be buffered – using an ethernet repeater/switch – or converted to fibre.
The maximum length for a multimode Fibre Link is 550m, and for singlemode is 2km.
The Centuri Routing card can be fitted with up to four individual Fibrelinks.
The BNC connector associated with each pair of Fibrelinks provides an output of system Wordclock.
Remote stageboxes may be connected to the Centuri core in any order.
