The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms. This is the same type of cable used in analog composite video setups, which potentially makes for easier "drop in" equipment upgrades (though may be necessary for long runs at the higher bitrates for older oxidising or lower grade of cable to replaced ...
SMPTE 259M is a standard published by SMPTE which "describes a 10-bit serial digital interface operating at 143/270/360 Mb/s." [1] The goal of SMPTE 259M is to define a serial digital interface (based on a coaxial cable), called SDI or SD-SDI. There are 4 bit rates defined, which are normally used to transfer the following standard video formats:
Serial Data Transport Interface is a way of transmitting data packets over a serial digital interface (SDI) datastream. This means that standard SDI infrastructure can be used. This means that standard SDI infrastructure can be used.
SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous serial communications protocol for intelligent sensors that monitor environment data. These instruments are typically low-power (12 volts), are used at remote locations, and usually communicate with a data logger or other data acquisition device.
SMPTE 292 is a digital video transmission line standard published by the Society of Motion Picture and Television Engineers (SMPTE). This technical standard is usually referred to as HD-SDI; it is part of a family of standards that define a serial digital interface based on a coaxial cable, intended to be used for transport of uncompressed digital video and audio in a television studio ...
The cables that carry digital video are also mostly serial—such as coax cable plugged into a HD-SDI port, a webcam plugged into a USB port or FireWire port, Ethernet cable connecting an IP camera to a Power over Ethernet port, FPD-Link, digital telephone lines (ex. ISDN), etc.

Level A format is the direct mapping of uncompressed 1080p (up to 60 fps) video into a serial digital interface at the nominal 3 Gbit/s. That is, one video signal, one video stream, in one cable. Level B-DL format is the mapping of dual-link HD-SDI/SMPTE 372M (i.e.: 1080p up to 60 fps) in a single serial digital interface at the nominal 3 Gbit ...
