Technical Field

[0001] This utility model relates to the field of HDMI cable technology, and in particular to an over-temperature alarm fiber optic HDMI cable that can be integrated into a distributed control system, suitable for scenarios such as automated factories and smart buildings. Background Technology

[0002] Fiber optic HDMI cables are high-definition multimedia interface cables that use optical fiber as the transmission medium. They have advantages such as long-distance transmission, strong anti-interference, and high bandwidth, and are suitable for scenarios with high signal quality requirements, such as home theaters, engineering cabling, and e-sports games.
