GIGALIGHT to Unveil Innovative 48G SDI Optical Interconnect Solution at IBC 2023 in Amsterdam

SHENZHEN, China - Sept. 13, 2023 - PRLog -- The IBC event is scheduled to take place from September 15th to 18th at the RAI Amsterdam Convention Center. GIGALIGHT (https://www.gigalight.com/) will be introducing its second-generation mini 48G-SDI (4X12G) broadcast-grade video optical transceiver kit solution at booth 5.B55.

8K represents the pinnacle of television standards, and it's recognized as the "key technology" for dominating the media landscape. Achieving a 12-bit color depth at 8K resolution is a monumental challenge for manufacturers. It not only demands rigorous adherence to HDR standards but also necessitates a significant jump in near-field transmission bandwidth, from 18G to 48G.

GIGALIGHT's revolutionary 48G-SDI (4×12G) video optical transceiver kit integrates four optical extenders and four 12G SDI optical modules with a wavelength division multiplexer, enabling transmission of four uncompressed 12G-SDI signals over 20km of single-mode optical fiber. Ideal for uncompressed 8K SDI baseband optical connections in broadcast, sports, and live productions.

This new second-generation 8K 48G SDI solution comprises a mini 48G extender with a QSFP optical interface and a 48G SDI QSFP+ PSM pluggable optical module. This solution boasts high integration and offers the flexibility needed for deployments. The mini optical extender features high-quality HD-BNC interfaces and incorporates 12G-SDI CDR clock data recovery chips to ensure impeccable signal quality.

The 48G SDI QSFP+ PSM4 pluggable optical module meets the stringent requirement of error-free transmission over 20km. It employs GIGALIGHT's pioneering 4X MINI-TOSA high-reliability optical device solution, complemented by low-power DML lasers, and supports four parallel 3G-SDI/12G-SDI signals. The optical interface uses MPO-12, and the module's power consumption is under 4W. Furthermore, for customers with specific needs, it can be tailored for CWDM4 wavelengths and can be transmitted through a single optical fiber after multiplexing using an external CWDM4 multiplexer.
