1. An electrical-optical device, comprising:
at least two optical fibers;
a grooved conductor that includes a recess that extends radially outward from a central portion of the grooved conductor to an end portion of the recess, wherein the at least two optical fibers are positioned within the recess, wherein one of the at least two optical fibers is adjacent the central portion of the grooved conductor and the other optical fiber is disposed between the optical fiber adjacent the central portion of the grooved conductor and the end portion of the recess;
wherein the at least two optical fibers are fixed in the position within the recess; and
a cladding disposed around the grooved conductor and over the end portion of the recess forming a tube, wherein the at least two optical fibers are maintained inside the recess of the grooved conductor, wherein the cladding includes a welded connection along a first end and a second end of the cladding, and wherein the cladding provides increased resistance to mechanical stress and reduced likelihood of gas intrusion to the at least two optical fibers and gas leakage to the electrical-optical device.
