GIGALIGHT Launches 48G-SDI Broadcast-Grade Video Optical Extender, Focusing On 8K Ultra HD Broadcast Market Applications

Shenzhen, China, July 27, 2022 – With the vigorous growth of the 8K ultra-high-definition broadcast market, users are putting forward new demands for the extension transmission of 8K uncompressed SDI baseband video. For 8K applications, SDI interfaces usually adopts 4x12G SDI connections. In regards to this interface application, GIGALIGHT introduces 48G-SDI (4X12G) broadcast-grade video optical transceiver kit solution. This solution fulfills the requirement of transmitting 4 uncompressed 12G-SDI signals over a 20km single-mode fiber, enabling users to quickly deploy 8K uncompressed SDI baseband fiber extensions and simplifying user operations.
GIGALIGHT’s 48G-SDI (4X12G) broadcast-grade video optical extender kit solution includes a transmitting optical transceiver, a receiving optical transceiver and two external power supplies. Each 12G-SDI channel is independent,the rate is backward compatible, and it is supporting any SDI working rate from 270Mbit/s to 12Gbit/s.
