2.5.3 Power supply
2.5.3. 1 Introduction
The devices that supply power to the optical network
are:
• the central control unit.
• the network controller.
If more power is necessary, you must install external
power supplies in the optical network. (refer to 41.5.2).
The devices below can connect to external power
supplies:
• LBB4410/00 Network Splitter (refer to chapter 41).
• LBB4414/10 Fiber Interface (refer to chapter 42).
2.5.3.2 DCN-CCU
The central control unit supplies power to:
• the optical network
• the DCN sockets.
For an overview of the maximum power that the central
control unit can supply refer to figure 2.1.

2.5.3.3 DCN-NCO
If a network controller is connected, it will supply power
to the optical network. In this case, the DCN-CCUs
then only supply power to the DCN sockets. If a glass
optical fibre is used to connect a remote CCU, this
CCU then supplies the power for that part of the optical
network.
The maximum power that each of the optical network
sockets of the network controller can supply is 55 W.
2.5.4 Overload indication
Each optical network socket of the central control unit
has a red LED that comes on to show that there is a
power overload. An overload occurs when the
necessary power for the devices is greater than that
supplied. The sockets are set to off and the devices
connected to the central control unit do not operate.
The socket checks every 8 seconds.
The network controller does not have an overload
indication.
Mains Note
If only one of the optical network sockets has a
50-60Hz T2.5A 250V
50-60Hz T2A H 250V
power overload, the two overload LEDs come
on, and the power will be removed from both
sockets.

2.6.1 Introduction
50-60Hz T2.5A 250V
50-60Hz T2A H 250V
Many devices in the optical network have two optical
network sockets that are interchangeable. You can use
the two optical network sockets to make a redundant
ring. The optical network uses two types of cable:
• Plastic Optical Fiber (POF).
• Glass Optical Fiber (GOF).
Mains
50-60Hz T2.5A 250V
50-60Hz T2A H 250V
Note
The two optical network connectors are the
same.
