The cables of the GBSR consist of power cables, PGND cables, and signal cables.
Distribution of the Power Switches in the GBSR
The GBSR can be configured with the BSC common power distribution box or the BSC high-power distribution box. Each of the six power outputs of the power distribution box supplies power to a component in the GBSR in a fixed way.
Connections of Power Cables and PGND Cables in the GBSR
The power cables in the GBSR are used to connect the PDF to the power distribution box. This ensures a stable power supply for the GBSR. The PGND cables are used to connect the cabinet to the PDF or to the grounding bar in the equipment room. This protects the cabinet from electrostatic discharge.
Connections of Signal Cables in the GBSR
The signal cables in the GBSR consist of the active/standby 75-ohm coaxial cable, active/standby 120-ohm twisted pair cable, optical cable, straight-through cable, inter-GTNU cable, Y-shaped clock cable, and PDB monitoring signal cable.
