Abstract
A cable containing at least one optical fiber and at least one material. The at least one optical fiber being at least partially embedded within the at least one material, and the at least one material forming a housing that protects the at least one optical fiber. The at least one material having a Shore A hardness of about 75 or less.
Claims43
A fiber optic cable comprising:
- at least one optical fiber;
- at least one material, said at least one material being at least one thermoplastic material comprising:
- (i) about 10% to about 100% by weight of thermoplastic polymeric molecules which have bonded to form a three dimensional network substantially throughout said at least one thermoplastic material;
- and (ii) about 0% to about 90% of one or more additives that do not cause undesirable optical performance;
- said at least one optical fiber being at least partially embedded within said at least one material, said at least one material forming a housing that protects said at least one optical fiber;
- and
- said at least one material having a Shore A hardness of about 50 or less.
