Abstract

Abstract An electro-optical transmission line for use in an interconnection system wherein an electrical signal is converted to an optical output signal by a light-emitting diode and the optical light signal is transmitted by an optical fiber bundle to a light receiving diode which converts the optical signal back to an electrical signal. The optical bundle is terminated at its ends with coaxial electrical contact assemblies which mount the diodes. The contact assemblies may be mounted in standard electrical connector members.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 121 words
An electro-optical transmission line comprising: at least one optical fiber; a coaxial electrical contact assembly at each end of said fiber; each said contact assembly including a shell and a pair of inner and outer contacts extending outwardly from one end of said shell, said outer contact surrounding said inner contact; a radiation-emitting device in one of said shells directed toward one end of said fiber and a photosensitive device in the other shell directed toward the other end of said fiber, each said device having inner and outer coaxial conductors electrically connected to the inner and outer contacts, respectively, of its corresponding contact assembly; and the respective ends of said fiber being connected to the other ends of said shells.
Claim 2
Dependent Claim 121 words
An electro-optical transmission line comprising: at least one optical fiber; a coaxial electrical contact assembly at each end of said fiber; each said contact assembly including a shell and a pair of inner and outer contacts extending outwardly from one end of said shell, said outer contact surrounding said inner contact; a radiation-emitting device in one of said shells directed toward one end of said fiber and a photosensitive device in the other shell directed toward the other end of said fiber, each said device having inner and outer coaxial conductors electrically connected to the inner and outer contacts, respectively, of its corresponding contact assembly; and the respective ends of said fiber being connected to the other ends of said shells.
Claim 3
Dependent Claim 19 words
