1. An optical fiber jumper cable comprising:
an outer jacket having an outer surface defining an outermost surface of the optical fiber cable and an inner surface defining a central bore;
a plurality of aramid fibers located in the central bore, wherein the plurality of aramid fibers has a total linear density such that the optical fiber jumper cable has an a1 acidity rating during burn as measured by EN 50267-2-3;
at least one optical fiber located within the central bore and surrounded by the aramid fibers, wherein the at least one optical fiber satisfies a proof test of 200 kpsi or greater and experiences less than or equal to 0.5% permanent fiber strain when exposed to a permanent tensile load of 100 N; and
at least one connector on an end of the optical fiber jumper cable.
