ARINC 818-2 on bi-directional
HIGH-SPEED COAX (HSC)
ARINC 818-2 on coax offers a robust option where a copper physical layer and bi-directional communication is desired. It is a natural successor to HOTLink II™, offering the same flexibility at greater link rates over common coaxial cable.
​
GRT now offers these ARINC 818 products in High-Speed Coax (HSC) versions:
HSC already offers link rates up to 3.1875 Gb/s, and GRT expects the rate to reach 6.375 Gb/s during 2016.
GRT's HSC Implementations
GRT's HSC implementations for ARINC 818 include a high-speed video path (for example, 3.1875 Gb/s) and a low-speed data return path (20 Mb/s) over a single coaxial cable. Using common coaxial cable, distances of 50 meters are possible, depending on the link rate and cable quality.
​
ARINC 818 HSC is ideal for applications where a bi-directional copper interface are required, such as high-resolution optical or infrared sensors and where the cable must pass through a slip ring.
​
In 2016, GRT introduced HSC Pantera switches capable of combining several ARINC 818 video systems onto a single multiplexed link.
Among HSC products are frame grabbers/graphics generators (left) and HSC SAMs and Pantera switches, which use the same box size (right) as their fiber counterparts.
An HSC Pantera 4x1 switch enables the controller to select an active camera and command it while receiving its video feed. Here Camera A is active.
An HSC Panetera switch concentrates simultaneous feeds from multiple cameras or sensors and transmits them on a single coaxial cable. A second switch acts as a splitter, sending individual feeds to individual monitors.
