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” on its own is not enough: we need to know whether the 1080 lines are progressive or interlaced. That determines whether 1.5 Gbps (HD-SDI) or 3 Gbps (3G-SDI) travel through the cable, and the data rate determines the cable diameter 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.
