Cable Requirements
Network cable
10/100 Mbps Ethernet CAT 5/5E UTP cables are applicable to the ANSI/EIA/TIA-568A/B and ISO/D.
Eight wires in the network cable need to be inserted in parallel into the top of the cable connector. The cable
connector needs to be crimped in position. When the cable connector is in position, ensure that the metal pieces of
the cable connector are parallel to each other and the clamp of the cable connector is intact.
SDI Signal Cable
In order to ensure the quality of the installation of the project, the HD-SDI and 3G-SDI signals have a high data
transmission rate of digital signals, it is necessary to correctly select the appropriate cable model. In the process of
installing a cable, it should be carefully and carefully, to avoid incorrect to fold, twist, bend the cable or to apply
various kinds of stress to the cable, so that the signal can be transmitted along the cable smoothly.
Different cable types have different physical characteristics, and the transmission length of the digital signal is not
the same.
Recommended cable Transmission signal Transmission distance
Belden 7731A 3G-SDI 120 m
