3.7.4Redundant cables

The example of the extended optical network (refer to figure 3.6) has no redundant cable. If the cable between the central control unit (DCN-WCCU) and the wireless access point (DCN-WAP) breaks, the central control unit cannot transmit data to the wireless access point. A solution for this problem is to use redundant cable (refer to figure 3.7 for an example).

figure 3.7: Redundant optical network

The example of the system without redundant cable (refer to figure 3.6) has no connection between the cobranet interface (LBB4404/00) and the central control unit (DCN-WCCU). The example of the system with redundant cable 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 65 W. If the optical network is defective near the central control unit, the other socket can supply power to all of the optical network.
