Figure 4.15: Redundant optical network
The basic system with no redundant cables has no connection between the Cobranet interface
(LBB4404/00) and the central control unit (DCN-CCU2). A system with redundant cables has a
connection between the Cobranet Interface and the central control unit. This connection
makes a ring. If a cable breaks, the optical network continues to operate.
The maximum total power of all devices in the redundant optical network is 85 W. If the
optical network is defective near the central control unit, the other socket can supply power
to all of the optical network.
Tap-offs
The network splitter (PRS-NSP) lets you make tap-offs. Tap-offs cannot be redundant. If the
cable between the network splitter and the digital audio expander (PRS-4DEX4), becomes
defective, the digital audio expander has no connection to the central control unit.
