What is HDMI optical cable?
HDMI optical fiber cable is an HDMI cable that uses optical fiber as the transmission medium. The principle of HDMI optical fiber cable is to integrate the photoelectric conversion circuit at the HDMI interface and use optical fiber as the transmission medium material; during the transmission process, there is an HDMI optical fiber cable transmitting end. The HDMI signal is converted into an optical signal and transmitted to the HDMI optical fiber line receiving end through optical fiber media. The receiving end then converts the optical signal into a lossless HDMI signal and outputs it to the display device.
HDMI fiber optic cable is mainly composed of three parts: transmitter, fiber optic cable, and receiver.
Transmitting end: convert HDMI signal into optical signal and output to optical fiber line
Optical fiber cable: connects the transmitting end to the receiving end and is responsible for the stable transmission of optical signals
Receiver: Convert the optical signal sent from the transmitter into HDMI signal and output it to the display device
advantage:
01. Long transmission distance
HDMI optical fiber cable transmission distance can generally reach more than 300 meters; during the long-distance signal transmission process (from electricity to light, light to electricity) the signal loss rate is basically zero, zero impedance and the signal is uncompressed (lossless); even over long distances The transmission can also reach 4K high-definition resolution (4:4:4); the traditional long-distance transmission signal of ordinary HDMI cable using copper as the transmission medium is prone to attenuation and distortion.
02. Radiation resistance
Because HDMI optical fiber cables use optical fiber media for transmission, they are not affected by external radiation and have stable signal transmission; traditional HDMI cables are easily affected by radiation because they use metal cables.
03. Small size and light weight
The diameter of the HDMI optical fiber cable is ultra-fine and light in weight. It is reduced by up to 60% year-on-year. The raw material is quartz, which saves metal materials and is conducive to the rational use of resources.
04. Ultra-high-speed bandwidth (18Gbps)
To ensure lossless transmission of 2K@60HZ and 4K@60Hz, it is necessary to meet the high bandwidth transmission requirements of 18Gbps; however, traditional hdmi copper cables are subject to signal attenuation and are difficult to meet. HDMI optical fiber cable uses optical fiber for transmission, with wider frequency band and larger communication capacity.
05.Insulation
Optical fiber lines are mainly made of non-metallic material quartz, which is insulated and safe.
