METHOD OF MAKING A FIBER OPTICAL CABLE ASSEMBLY
First Claim
1. A process for forming a fiber optical cable assembly comprising the steps of:
- (a) subjecting a first reinforcement yarn having a linear density of from 150 to 12000 dtex, a tenacity of from 10 to 65 g/dtex, a modulus of from 150 to 2700 g/dtex, and an elongation to break of from 1 to 8 percent coated with a water-impermeable thermally reversible cross-linked polymeric coating to a temperature of from 45 to 200°
C. for sufficient time to convert the protective coating via bond cleavage into a water-swellable super absorbent polymer.(b) combining one or more of the first reinforcement yarns from step (a) with one or more optical glass fiber transmission media and(c) applying a protective sleeve over at least one assembly of step (b).

Abstract
A process for forming a fiber optical cable assembly comprises the steps of (a) subjecting a first high yenacity reinforcement yarn such as para-aramid that is coated with a water-impermeable thermally reversible cross-linked polymeric coating to a temperature of from 45 to 200° C. for sufficient time to convert the protective coating via bond cleavage into a water-swellable super absorbent polymer, (b) combining one or more of the first reinforcement yarns from step (a) with one or more optical glass fiber transmission media and (c) applying a protective sleeve over at least one assembly of step (b).
