HP Instruction Sheet
D16678-00
If a fibre link is broken, operation of the ring continues by making use of the secondary optical fibre
route as below:
If multiple breaks occ ur, operation is maintained with all the units still physically connected to the
receiver. For the scenario shown below camera signals and control would now be lost from cameras 1,
2 and 3 as there is now no physical connection between the transceivers and the receiver. However
operation of cameras 4,5,6,7 and 8 remains fully functional.
Note that where necessary repeaters can be added at nodes to increase the average distance
between nodes.
