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 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 IRD is the interface between a receiving satellite dish or Telco networks and a broadcasting facility video/audio infrastructure. Professional IRDs have various features that consumer IRDs lack such as: SDI outputs. ASI inputs / outputs. TSoIP inputs. AES/EBU Audio decoding. VBI reinsertion. WSS data and pass through. Transport stream ...
For instances where the full-duplex nature of SPI is not used, an extension uses both data pins in a half-duplex configuration to send two bits per clock cycle. Typically a command byte is sent requesting a response in dual mode, after which the MOSI line becomes SIO0 (serial I/O 0) and carries even bits, while the MISO line becomes SIO1 and ...

The only similarity between SDI and G.703 is that they are serial digital transmission channels typically carried over coaxial cable, but as the bandwidth, technologies, equipment and application domains so different, I think that any mention of a IT/telecom standard like G.703 here is irrelevant or misleading in a video context (which "SDI ...
Software-defined infrastructure (SDI) is the definition of technical infrastructure controlled by computer hardware, that is entirely under the control of software. It operates independent of any hardware-specific dependencies and is programmatically extensible. Drive for innovation boosts demand for software-defined equipment.
DECs Standard Disk Interconnect (SDI) was an early example of a modern bit serial interface. Fibre Channel (FC) is a successor to parallel SCSI interface on enterprise market. It is a serial protocol. In disk drives usually the Fibre Channel Arbitrated Loop (FC-AL) connection topology is used.
