7.4 Fiber Cable Connections
When optical cables are used to link the power unit and the control board, a special Optical Cable Adapter Board connected to the
control board D-connector is used.
The control unit uses 24 V DC supplied from the ASIC board, which is on the left side of the power unit 1.
Each fiber optic cable has a number 1...8 and 11…18 (1...7 for FI9-FI10 and FI13) marked on the cable shield at both cable ends. The list
of the optic signals can be found in the following figures and table.
