ABSTRACT:
An optical fiber unit having a sheath and a plurality of optical fiber elements loosely housed in the sheath. The sheath is coated with particles of an adherence reducing substance and has a radial thickness that is not substantially greater than 0.3 mm. The coating of adherence reducing particles is applied as a liquid coating. The liquid coating is a dispersion of the particles and heat is applied to evaporate the liquid content of the liquid coating to produce a dry coating of particles on the sheath.
