3g Sdi Cable Length

It is known that sdi interfaces can be roughly divided into three types.

3g sdi cable length.

Sd sdi 270mbp smpte259m hd sdi 1 485gbps smpte292m and 3g sdi 2 97gbps smpte424m. Hd 1 5g sdi 1 5 gb s 3 0 gb s widescreen sd sdi. Serial digital interface sdi is a family of digital video interfaces first standardized by smpte the society of motion picture and television engineers in 1989. Whether you are watching a live show or just regular television sdi cable is what that is bringing you that feed.

However coax is not the only medium available. This provides a. 3g sdi systems require higher frequencies to operate making component engineers interconnect cable choices critical for proper system operation. Reference sdi maximum cable distance chart.

The above graphs do not represent the exact cable length possible. That s when we decided to create the first cable designed specifically to carry signals up to 100m for 3g sdi 1794a and we did so about five years ago. This was a slightly larger cable than 1694a. Sdi cable was first to standardize in 1989 but it s 2019 now.

Serial digital video may be routed through fiber optic cable for essentially unlimited distances depending on the system configuration.

For example itu r bt 656 and smpte 259m define digital video interfaces used for broadcast grade video a related standard known as high definition serial digital interface hd sdi is standardized in smpte 292m.

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. The enhancements are mostly do to increase signal quality and transmit more data. Sdi cable has gone through many upgrades over the decades. 177 mb s 270 mb s 360 mb s smpte st 424.

Because of this the exact maximum cable length possible will vary. The military spec cable rg179 is frequently used for 3g sdi systems but is outdated and was originally designed to serve analog not digital applications. When installing a cable in a system and it is approaching.
