1. A fiber optic bundle for incorporation into a cable to support an application in a well, the fiber optic bundle comprising:
a microbundle having:
a first fiber optic thread;
a second fiber optic thread stranded against the first fiber optic thread at a zero degree lay angle, wherein the second fiber optic thread is in direct contact with the first fiber optic thread;
a third fiber optic thread stranded against the first fiber optic thread and the second fiber optic thread at the zero degree lay angle, wherein the third fiber optic thread is in direct contact with the second fiber optic thread;
a filler support disposed at a central axis of the microbundle to structurally support the first fiber optic thread, the second fiber optic thread, and the third fiber optic thread; and
an interstitial filler filling interstitial spaces of the microbundle, the interstitial filler comprising a polymer filler; and
a jacket disposed about the microbundle to form a filled bundle, wherein the jacket is in direct contact with the interstitial filler of the microbundle.
