In the connector at both ends, the internal conductors are conductive and the
external conductors are conductive, while the internal and external conductors
should not be shorted.

Currently the impedance converter coded "5160087" is used to convert the 75
Ω
trunk
cable into the 120
Ω
trunk cable. The following section describes the impedance
