Abstract
A fiber optic cable suitable for indoor applications includes a core tube surrounding a plurality of coated optical fibers; a jacket formed of a polymer material surrounding the core tube; and at least one layer of strength members disposed between said core tube and said jacket. The jacket has an outer diameter of not greater than about 7 to 12 mm and the coated optical fibers experience a short-term increase in signal attenuation of no more than about 0.01 dB when the cable is looped in a radius of 5 centimeters.
Claims16
A fiber optic cable suitable for indoor applications, comprising:
- a core tube surrounding a plurality of coated optical fibers;
- a jacket formed of a polymer material surrounding said core tube;
- and
- at least one layer of strength members disposed between said core tube and said jacket, said strength members perform an anti-buckling function in said fiber optic cable whereby said coated optical fibers experience a short term delta attenuation of no more than about 0.01 dB when the cable is looped in a radius, the radius comprising a loop of about five centimeters.
A fiber optic cable, comprising:
- a cable jacket;
- a core tube;
- said core tube having at least one optical fiber therein and an outside diameter of about 6 mm or less;
- and
- strength members, said strength members generally encircling said core tube, at least one of said strength members being contiguous with said core tube, being contiguous with said jacket, and being contiguous with at least one other of said strength members for minimizing attenuation in said at least one optical fiber.
A fiber optic cable, comprising:
- a cable jacket;
- a core tube, said core tube having at least one optical fiber therein and an outside diameter of about 7 mm or less;
- and
- strength members, said strength members being arranged in a generally encircling, staggered pattern about said core tube wherein a first layer of said strength members is generally arranged so that strength members of the first layer are in contact with said core tube, and wherein a second layer of said strength members is generally arranged so that strength members of the second layer are in contact with said jacket but are not in contact with said core tube.
