Abstract
A low smoke, low toxicity fiber optic cable that provides an intermediate surface that facilitates bonding to optical connectors such as LC connectors, is provided. In a preferred embodiment, the inventive cable exhibits improved dimensional stability by minimizing or eliminating shrinkage stress on the optic fiber core.
Claims36
A fiber optic cable assembly, which comprises:
- (1) a fiber optic cable comprising at least one optical fiber, a primary buffer member circumferentially surrounding each optical fiber, and a secondary buffer member circumferentially surrounding the primary buffer member, wherein the secondary buffer member is prepared from, or has an outer surface or layer prepared from, a material selected from the group of bondable polyimides and bondable fluoropolymers;
- (2) a connector adapted to receive the fiber optic cable;
- and
- (3) an adhesive which serves to bond the bondable polyimide or fluoropolymer of the secondary buffer member to the connector to form a unitary structure,
- wherein, when tested in accordance with Method Number 2009-1 of SAE-AS-13441 (January 1998), the fiber optic cable assembly exhibits a bond strength of at least about 2 Newtons per centimeter in the adhesive coated area(s) thereof.

A low smoke, low toxicity fiber optic cable that comprises:
- (1) at least one optical fiber;
- (2) a primary buffer member circumferentially surrounding each optical fiber;
- (3) a secondary buffer member circumferentially surrounding the primary buffer member, wherein the secondary buffer member is prepared from, or has an outer surface or layer prepared from, a material selected from the group of bondable polyimides and bondable fluoropolymers;
- (4) a strength member circumferentially surrounding the secondary buffer member;
- and
- (5) an outer protective jacket circumferentially surrounding the strength member,
- wherein, when tested in accordance with Boeing Specification Support Standard BSS 7324 (Dec. 2, 1998) Smoke Emission Test Method, the cable produces, at four minutes in the flaming mode, a smoke with a specific optical density of less than 100.
