Patent ID: 7941022

Claim:
A fiber optic system comprising: a) a high power link comprising; i) a single fiber dual optical link; ii) a laser power source coupled via a first wavelength selective coupler to the single fiber dual optical link; iii) a laser energy power converter coupled via a second wavelength selective coupler to the single fiber dual optical link; and b) an optical data link comprising: i) the single fiber dual optical link; ii) a data transmitter coupled via the first wavelength selective coupler to the single fiber dual optical link; and iii) a data receiver coupled via the second wavelength selective coupler to the single fiber dual optical link; c) wherein the single fiber dual optical link comprises a clad fiber comprising a core with a first index of refraction and a first cladding with a second index of refraction, and wherein the first index of refraction is greater than the second index of refraction; and d) wherein the clad fiber further comprises a second cladding with a third index of refraction, the third index of refraction being less than the second index of refraction.
