Claim:
1. A fiber optic cable comprising at least one subassembly, and the at least one subassembly comprising: between 1 to 12 optical fibers; a plurality of reinforcing strands which are each free of any halogens; a first jacket being free of any halogens and having a thickness of between about 0.254 to about 0.305 mm; and the first jacket surrounding and completely encasing the 1 to 12 optical fibers and the plurality of reinforcing strands to form the at least one subassembly; wherein the first jacket is manufactured from a material which has a limiting oxygen index (LOI) of at least 40 and a shrinkage of the first jacket being no greater than about 3.5%; the fiber optic cable has a crush resistance of at least 35N/cm, allows less than a 0.24 db/km increase of optical attenuation from −20 to 70° C. at 1550 nm for non bend-resistant single mode fiber and meets requirements according to each of IEC 60332-3-24 (Flame Spread), IEC 61034-2 (Low smoke), and IEC 60754-1&2 (non-Halogen); and the first jacket has a flexural modulus of about 40,000 psi.
