Composite optoelectronic HDMI cable
A composite optoelectronic HDMI cable having the advantages of low signal attenuation, long distance application, ease of installation and light weight is disclosed. Specifically, a fiber optic bundle unit is provided in the HDMI cable instead of the existing copper wire or alloy conductor, and the overall outer diameter is reduced by half and the weight is reduced by three quarters when compared to the copper wire or alloy conductor. It is very convenient for long-distance use or project laying.
1. A composite optoelectronic HDMI cable, comprising:
a center wire set, comprising:
a fiber optic bundle unit containing a plurality of fiber cores for transmitting optical signals, said fiber cores being composed of OM3-300 fibers or OM4-550 fibers;
a plurality of signal control lines arranged around said fiber optic bundle unit for transmitting electronic signals;
a plurality of fillers arranged between said fiber optic bundle unit and said signal control lines to isolate said fiber optic bundle unit and said signal control lines and to increase the tensile and anti-bending strength of said fiber optic bundle unit and said signal control lines; and
a ground wire mounted between two adjacent said signal control lines to provide electronic signals to ground;
a shielding layer wrapped about said center wire set after said center wire set being stranded subject to a fixed twist pitch and direction; and
a flame-retardant jacket surrounding said shielding layer center to protect said wire set and said shielding layer.
2. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein the preferred color of said fiber cores of said fiber optic bundle unit is brown, green, blue or orange.
3. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said fiber optic bundle unit further comprises a shrinking sheath surrounding said fiber core, said shrinking sheath being selected from the group of polyethylene, fire-retardant polyethylene, cross-linked polyethylene and polyfluorinated ethylene propylene.
4. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said signal control line comprises a center conductor material composed of a single strand of tin-plated copper, bare copper, silver-plated copper, tin-plated copper, bare twisted copper, or silver-plated copper twisted copper.
5. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said signal control line comprises an outer insulative layer composed of polyethylene, foamed polyethylene, polyvinyl chloride, cross-linked polyethylene or polyfluorinated ethylene propylene.
6. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said fillers are made of aramid fiber, PP tear rope, cotton yarn or nylon yarn.
7. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said fiber optic bundle unit and said signal control lines are twisted into a circular arrangement.
8. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said shielding layer is composed of polyester tape, aluminum foil, copper foil Mylar tape, cotton paper or Teflon tape.
9. The composite optoelectronic HDMI cable as claimed in claim 1 , wherein said flame-retardant jacket is made of polyvinyl chloride, low-smoke halogen-free flame-retardant polyolefin, nylon elastomer, thermoplastic elastomer, polyurethane elastomer or crosslinked polyethylene.
