Silicon Line GmbH, a developer of optical link technology for consumer and commercial applications, has launched its HDMI 2.1 active optical cable modules sampling program for original equipment manufacturers (OEMs) and 8K TV manufacturers.

Silicon Line has played an active role in the HDMI Forum’s Test Subgroup, which is working to incorporate active optical technology and other technologies into the final compliance test specification (CTS) for cables. The sampling program is expected to provide an opportunity for cable manufacturers and partners to accelerate their time to market.

In addition to extensive laboratory research, Silicon Line has field-tested its modules through its regular participation in HDMI plug fests where engineers have been able to evaluate the modules with more than 100 combinations of next-generation sources and display products. The company is therefore confident the HDMI 2.1 modules will be in full and speedy compliance shortly after the CTS is released.

The Silicon Line HDMI 2.1 modules support all features of the standard’s latest spec, including 48 Gbps bandwidth, eARC (enhanced Audio Return Channel) and a reduction in video latency for gaming consoles. In addition, the upcoming HDMI 2.1 compliant cables powered by Silicon Line’s modules offer the advantage of not requiring external power and are backwards compatible in supporting the previous HDMI 2.0 and HDMI 1.4 specifications.
