A family of lubricants for use in fabricating optical fiber cables having stacked optical fiber ribbons is disclosed. Each of the lubricants, is characterized by a surface tension less than 34 dynes per centimeter, a contact angle of less than 44 degrees and a viscosity appropriate for the cabling application.

Lubricant for central core fiber optic cable having stranded ribbons

An optical fiber cable which is constructed so as to minimize optical transmission loss, and which comprises one or more compliant core units retained within a surrounding sheath. Each compliant core unit is composed of a bundle of parallel optical fibers, such as a stack of ribbons, enclosed in and supported by a compliant unitizing structure. The structure may derive its compliance from a foamed material, such as polyethylene, that is extruded to surround the fiber bundle. The foam material sufficiently cushions the bundle of fibers from external stresses that are applied when the cable is bent or encounters compressive loading.

Optical fiber cable

A modular optical fiber ribbon has a repetitive color identifier arrangement for the individual coated fibers defining one or more adjacent modules. Each module is identified by a digital code imprinted or otherwise marked on the top surface of the ribbon so that each individual fiber in the entire ribbon structure is uniquely identified. Each module or portion thereof can be broken out from the ribbon by means of a break-out tool which is sufficiently hard to cut the matrix bonding material which holds the fibers in the ribbon configuration, but which is not hard enough to cut the fiber coating.
