First Claim
Patent Images
1. The process of preparing optical fibers for loading into a dry core cable comprising the steps of:
- exposing optical fibers to a lubricant-dispensing device;
coating the fibers with a lubricant and an additive for said lubricant;
pressing the fibers together in a manner that allows said lubricant to bond the fibers together in a single stack.

Abstract
A family of oil or fluid-based lubricants with an additive, for use in fabricating optical fiber cables having loose fibers or stacked optical fiber ribbons is disclosed. The additive, which can be either fumed silica, fumed alumina, or block polymers, lowers the surface tension and contact angle, and increases the viscosity and wettability of the lubricants.
