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 in sleeves which are threadedly engaged with coaxial electrical contact assemblies.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
In an electro-optical transmission line: at least one optical fiber; a coaxial electrical contact assembly at an end of said fiber; 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; an optoelectronic device in said shell directed toward said end of said fiber, said device being electrically connected to said inner and outer contacts; and coupling means on said end of said fiber readily removably connecting said fiber end to the other end of said shell.
Claim 2
Dependent Claim
