Will any BNC cable work for SDI?
BNC Connectors on SDI SDI carries 16 channels of pulse-code modulation or PCM audio and uncompressed video that is digital in nature. As the signal’s bandwidth can extend on the gigahertz range, SDI cables can no longer handle this. It must use a proper BNC connector to handle this digital signal.
Can you use RG59 for SDI?
SDI can use RG-59 and RG-6 cable, although RG-6 cable is necessary for long runs and preferred in general. RG-59 cable, while cheaper, is less suitable for runs much over 100′. Also, be aware that RG-59 comes in 50 Ohm and 75 Ohm versions. 75 Ohm cable is needed for SDI.
What kind of connectors do SDI cables use?
Serial Digital Interface (SDI) is a digital video interface that is used for the transmission of uncompressed, unencrypted digital video signals for professional video equipment. Standard SDI cables are terminated with BNC connectors and have a nominal impedance of 75 Ohms.
Is SDI a 75 ohm cable?
SDI is a professional video standard developed for broadcast video operations. Where the original BNC cable comprised a 50-Ohm connector and RG-58 cable, an SDI cable uses 75-Ohm connector and RG-6 cable. Thicker cable and better connectors allow SDI to carry higher bandwidth signals.
What is SDI cable made of?
For transmission of HD video signal up to 1080p, the HD-SDI coaxial cable features a double sided aluminium foil and tinned copper wire braid, a foamed PE (polyethylene) dielectric and a 1.02mm solid bare copper conductor.
How long can you run an SDI cable?
Cabling and Loss HD-SDI is regularly transmitted over low-loss digital video grade RG6-style coaxial cable up to a nominal maximum distance of about 100 meters.
Is SDI the same as coaxial?
An SDI cable is a coax cable rated for SDI signal. Typically SDI cables have BNC ends on them. A coaxial cable can have BNC, F, or split out bare wire for many different applications. A coax cable is a cable with 2 paths: a center conductor and a shield.
