Abstract
At least one buffered optical fiber, and methods for manufacturing the same, including an optical fiber and a buffer layer. The buffer layer generally surrounds the optical fiber and has a low-shrink characteristic that preserves optical performance during, for example, temperature variations. In other embodiments, the at least one buffered optical fiber may be a fiber optic ribbon.
Claims44
A buffered optical fiber comprising:
- at least one optical fiber having a core, a cladding and at least one coating;
- and
- a buffer layer generally surrounding said optical fiber, wherein said buffer layer has a portion thereof generally contacting a portion of said at least one coating, said buffer layer having an average shrinkage of about 3 mm or less from a first end of said buffered optical fiber, and said buffer layer having an average strip force value of about 5 Newtons or less.
A method of manufacturing a buffered optical fiber comprising:
- paying off at least one optical fiber;
- and
- extruding a buffer layer around said at least one optical fiber, said buffered optical fiber has a portion thereof generally contacting a portion of said at least one coating of said at least one optical fiber, wherein said buffer layer has an average shrinkage of about 3 mm or less from a first end of said buffered optical fiber, and said buffer layer having an average strip force value of about 5 Newtons or less.
A buffered optical fiber comprising:
- at least one optical fiber;
- and
- a buffer layer generally surrounding said optical fiber, wherein said buffer layer has an average shrinkage of about 0.5 mm or less from a first end of said buffered optical fiber, and said buffer layer having an average strip force value of about 5 Newtons or less.
