3.7.4 Redundant 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 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.
