Transmitting full-spec 8K video signals using a single cable

Panasonic Corp. has created what it describes as a single cable and connector solution that allow the transmission of uncompressed full-pec 8K video signals. Presently, 4K-equivalent images are transmitted using four HDMI cables to transmit video signal via connector-equipped cables from an 8K signal source or other devices to an 8K display, and then they are combined to show in 8K resolution by using image processing. Panasonic's connector-equipped cable, which uses plastic optical fibre technology, can achieve the transmission of full-spec 8K video via a single cable, with improved bandwidth and length, the company stated.

High-speed transmission over optical fibre connector can be achieved when the optical axes are completely aligned. However, when the equipment and the cable's connection portions are detachable, it is difficult to precisely align optical axes at the connection, leading to poor connectivity and other defects. That has hampered the deployment of optical fibre cables in video transmission cables with detachable connectors.

Working with KAI Photonics Co. Ltd, a venture from Japan's Keio University, Panasonic developed connector-equipped cables that adopt "plastic optical fibre and its connection technology using ballpoint-pen type interconnect." Further, by applying Panasonic's technology for the multi-level modulation of broadband signals, a transmission bandwidth exceeding 100Gb/s was achieved with a single cable.

Anticipating the spread of the corporate use of 8K devices in the B2B market, Panasonic aims to make this innovative connector cable technology an international standard.
