19.3. RF combined ports
These ports should be directly connected to the radiating antennas through RF
jumper cables.
Unused RF output ports must be terminated with a dummy 50Ω load. Optional
boosters (TFB family) also can be connected to one or both of the combined ports
for additional RF downlink power.
19.4. Optical fibres connection
Optical connectors need to have proper alignment and mechanical support. When
inserting an optical connector, take care to handle it smoothly enough so as not to
damage the fibre. Remove the dust cap only immediately before making
connections.
