HDMI® Technology is the foundation for the worldwide ecosystem of HDMI-connected devices; integrated with displays, set-top boxes, laptops, audio video receivers and other product types. Because of this global usage, manufacturers, resellers, integrators and consumers must be assured that their HDMI® products work seamlessly together and deliver the best possible performance by sourcing products from licensed HDMI Adopters or authorized resellers. For HDMI Cables, consumers can look for the official HDMI® Cable Certification Labels on packaging. Innovation continues with the latest HDMI 2.2 Specification that supports higher 96Gbps bandwidth and next-gen HDMI Fixed Rate Link technology to provide optimal audio and video for a wide range of device applications. Higher resolutions and refresh rates are supported, including up to 12K@120 and 16K@60. Additionally, more high-quality options are supported, including uncompressed full chroma formats such as 8K@60/4:4:4 and 4K@240/4:4:4 at 10-bit and 12-bit color.

Their USB Type-C to HDMI optical cable supports 8K at 60Hz and can extend up to 40 meters, combining video and USB 4 data at 20G. The HDMI 2.1 AOC line features an ultra-slim, transparent design that reaches up to 300 meters, with visible internal laser fiber. An armored variant adds ruggedized durability for runs exceeding 100 meters, supporting both HDMI 2.1 and 2.0 specifications.
The company also showcased specialized form factors, including flat cables designed for under-carpet detector installations and HDMI MPO cables with MTP connectors targeted at medical equipment deployments. Their optical modules use a low-pressure injection molding process to protect internal PCBs, with versions available for HDMI, USB-C, and RJ-45 fiber applications. Development spans from legacy HDMI 1.4 through upcoming HDMI 2.2 compliance.
TSB-branded calibration equipment was highlighted as a key quality-control asset, following the company’s acquisition of compound calibration technology from JPEG. This facility enables tighter manufacturing tolerances. The company also confirmed TAA compliance for products destined for the US government market, addressing federal procurement requirements.
At InfoComm, 8Klink and TSB supplies longer-reach cabling to integrators and exhibitors managing large-format displays. Their braided cable jackets and modular connector designs serve installations requiring reliable high-bandwidth video transport across extended distances in professional AV environments.
