Abstract:
A method of providing TV signals and bidirectional telephonic communications to a multiplicity of subscribers through a single optical fiber comprising the steps of:transmitting light at a first wavelength carrying telephonic signals downstream from a first plurality of telephone related devices and at a second wavelength carrying TV signals downstream from a TV signal source through an optical fiber from a first end to a second end; receiving said first wavelength of light and generating first electrical signals within a first frequency band and representative of said plurality of telephonic signals; receiving said second wavelength of light and generating second electrical signals within a second frequency band and representative of said TV signals; transmitting said telephonic electrical signals to a plurality of telephone related devices and said second electrical signals to a plurality of TV signal receiving devices; generating a plurality of upstream or return electrical telephonic signals at said first frequency band representative of return telephonic information and a plurality of return or upstream TV related electrical signals at a third frequency band representative of TV related information from said plurality of subscribers; multiplexing said electrical signals carrying said return telephonic signals at said first frequency band and said TV related electrical signals carrying said TV related information at said third frequency band; receiving said multiplexed electrical signals and generating light at said first wavelength representative of said return telephonic signals and said TV related information; transmitting light at said first wavelength to carry said return telephonic signals and said TV related information through said optical fiber from said second end to said first end; receiving said light carrying said return telephonic signals and said TV related information and generating a plurality of third electrical signals representative of said return telephonic signals and a plurality of fourth electrical signals representative of said TV related information; and transmitting said third electrical signals to said first plurality of telephone related devices and said fourth electrical signals to said TV signal source.
