To know which coaxial cable can be used to transmit a particular digital video signal, you must know exactly the most critical signal that is intended to be sent by that cable.
If our fixed parameter is the distance (since we know that we want to cover about 100 m) we have to know the definition of the image that we want to transmit.
“1080” as data does not solve much since within 1080 lines we need to know if it is progressive or interlaced video. It depends on this data that 1.5 Gbps (HD-SDI) or 3Gbps (3G-SDI) are transmitted through the cable and depending on the data capacity to be transmitted, a cable with one diameter or another is required.
Following this example with Pinanson cables for 100 m and a 1080i signal you can use the VDK6.0 cable and for 1080p the VDK7.0 cable.
