Abstract
A fiber optic cable having at least one optical fiber such as a microstructured bend performance optical fiber disposed within a protective covering. The protective covering is highly flexible and the fiber optic cable has extremely low delta attenuation when aggressively bent compared with the conventional fiber optic cable designs. By way of example, the delta attenuation of one fiber optic cable design is about 0.33 dB or less when wrapped 3 turns about a 7.5 millimeter mandrel at a reference wavelength of 1625 nanometers. Other variations of the present invention include a connector attached to the fiber optic cable.
Claims22
A fiber optic cable, comprising:
- at least one optical fiber;
- a protective covering, the protective covering being highly flexible and provides a bend control mechanism for inhibiting bending of the at least one optical fiber at a diameter of 5 millimeters or less, wherein the protective covering has an ultimate elongation of about 500% or more measured according to DIN 53504.
A fiber optic cable, comprising:
- at least one optical fiber, the at least one optical fiber being a microstructured bend performance optical fiber;
- a protective covering, being highly flexible and provides a bend control mechanism for inhibiting bending of the at least one optical fiber at a diameter of 5 millimeters or less, wherein the protective covering has an ultimate elongation of about 500% or more measured according to DIN 53504 and the protective covering is coupled for inhibiting buckling of the at least one optical fiber therein.
A fiber optic cable, comprising:
- at least one optical fiber, the at least one optical fiber being a microstructured bend performance optical fiber having a buffer layer thereon;
- at least one strength member;
- a protective covering, being highly flexible and provides a bend control mechanism for inhibiting bending of the at least one optical fiber at a diameter of 5 millimeters or less, wherein the protective covering has an ultimate elongation of about 500% or more measured according to DIN 53504 and is coupled about the at least one strength member for inhibiting buckling of the at least one optical fiber therein.
