Notice!
The Integrus transmitters do not use power from the system. In a multi CCU system, slave
CCUs do not use power from the optical network, nor do slave CCUs deliver power to the
optical network.
Power supply
The DCN-CCU2 supplies power to the optical network (refer to section DCN-CCU2 and DCN-
CCUB2 Central Control Units, page 14 DCN-CCU2).
If more power is necessary, you must install external power supplies in the optical network.
The devices below can connect to external power supplies:
– PRS-NSP Network Splitter (refer to PRS-NSP Network Splitter, page 57).
– PRS-FINNA Fiber Interface (refer to PRS-FINNA Fiber Interface, page 58).
DCN-CCU2
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 the
figure.
Figure 4.9: Optical network power supply: DCN-CCU2
If the DCN-CCU2 is configured as a master CCU in a multi CCU system or the DCN-CCU2 is in
stand-alone mode, it will supply power to the optical network. If a glass optical fiber is used to
connect a remote slave CCU, the optical fiber interface needs an external power supply. Refer
to chapter ‘Power supply’ earlier in this chapter.
