Stageboxes & Fibre Links

The C-SB S tagebox utilises f ibre-optic c onnection bet ween itself an d the Cent uri Proces sor. This has the advantages of noise immunity, reduced weight and bulk of wiring and the elimination of earth loops. A separate control si gnal (for gain, pad, f ilter etc .) is car ried o ver t he SSL ether net network. This c ontrol signal can be converted into fibre optic for runs longer than 100m.

The standard connectors for the fibre links are duplex LC 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 o ptions. 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 at 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 eight Fibrelinks. Thes e are arranged in four group s of two labelled as ‘Port 1’ to Port 4’.

Note: Each Port on the Routing/Link card actually provides up to four separate connections (two pairs). Connections numbered 1 and 3 are for the primary Fibre Link and numbers 2 and 4 are reserved for the optional redundant links.

Remote stageboxes may be connected to the Centuri core in any order.
