ABSTRACT:
A gas blocked fiber optic cable (10). A cable (10) having a fiber glass epxoy rod (12) which is top coated with EVA-Copolymer (28) and surrounded by fiber optic cables (16). Optical fibers (16) are enclosed in buffer tubes (18) filled with gel (20). Interstitial filling (28) surrounds buffer tube (18). Acid terpolymer top coat (24) bonds filler (28) to buffer tubes (18) preventing gas migration throughout the length of the cable. Black thermo plastic elastomer (30) layer surrounds filler (28) which is surrounded by the outer most polyethylene jacket (32) which is UV resistant.
