Connect a Juggler Optical Data Bus
Connect a Juggler Optical Data Bus
Jugglers in a system should be racked adjacent to each other, since optical connections must be
short and loop freely. If you are using multiple Jugglers on a data bus, make these connections first,
before inputs and outputs; they can become quite congested with many units.There are two bus
configurations, 4 and 8 lane, with each lane having a capacity of up to the equivalent of UHD 60 fps
10-bit 4:4:4.
Please note that as a critical component, optical cables used should be supplied or approved by
7thSense. Cables do not need to be short but the minimum bend radius of a free-hanging cable
should be not less than 10 times the cable outside diameter.
This page covers the physical cabling of a single bus. For an explanation of how this works, and the
use of the data bus in the Compere software, see the relevant sections in the Compere 1.0-5 User
Guide:
Ø
Bus Connections in a Juggler System (bus individual inputs)
Ø
Bridging Two 8-Lane Buses (e.g. to provide redundancy)
Ø
Output Canvas Bus (bus the whole canvas)
How your Juggler system is bused will depend on your overall requirements, and can include
combinations of bus types.
8-Lane ‘Full’ Bus
With the MPO (Multi-Fibre Push-on) optical fibre option, twice the bandwidth is available. Each fibre-
optic cable carries 8 lanes, 4 in each direction:
Units are daisy-chained unit to unit, 1 to 2 and loop back from the last unit to the first in the same way.
