Optical fiber cable including optical fibers organized into lumens for identification

An optical fiber cable, comprising:

• a cable jacket comprising an inner surface and an outer surface, the inner surface defining a central bore along a longitudinal axis of the optical fiber cable and the outer surface defining an outermost surface of the optical fiber cable;
• a first lumen disposed within the central bore, the first lumen comprising a first membrane having a thickness of 0.15 mm or less and surrounding a first plurality of optical fibers;
• a second plurality of optical fibers disposed within the central bore and outside the first lumen.

A method of manufacturing an optical fiber cable, comprising:

• extruding a first membrane around a first plurality of optical fibers to form a first lumen, wherein the first membrane has a thickness of 0.15 mm or less;
• extruding a jacket around the first lumen and around a second plurality of optical fibers such that the second plurality of optical fibers is outside of the first lumen.
