Abstract: Vented optical tube. At least some illustrative embodiments are conduits comprising a tube having a wall defining an interior volume of the tube. One or more optical fibers are disposed within the interior volume. The wall includes a plurality of vents passing from an outer surface of the wall to the interior volume, the plurality of vents disposed along a length of the tube, and wherein the vents are configured to convey a fluid in contact with the outer surface into the interior volume of the tube.

Abstract: At least some illustrative embodiments are including a method exposing a first optical fiber and a second optical fiber disposed within an interior volume of a first tube. A splice is formed between the first optical fiber and a third optical fiber, the splice joining an end of the first optical fiber and an end of the third optical fiber. A second tube is disposed the first, second, third optical fibers and the splice between the first and third optical fibers, wherein an end of the second tube adjoins an end of the first tube to form a structure comprising either an overlapping structure; or an abutting structure.

Abstract: Staggered Splices. At least some illustrative embodiments are apparatus including a tube having a wall defining an interior volume, first and second optical fibers disposed within the interior volume and the first and second optical fibers joined at a first splice. Also included are third and fourth optical fibers disposed within the interior volume, the third and fourth optical fibers joined at a second splice. The first splice and the second splice have an axially spaced-apart relationship within the interior volume of the tube.
