Sheathed optical fiber cable |
August 22, 1989 |
| Optical fiber cables have an inner sheath extruded or otherwise applied to surround optical fibers. If the fibers are coupled to the sheath, substantial shrinkage of the sheath during manufacturing induces microbending losses in the optical fibers. The inventive technique involves ch |

Single mode optical fiber ribbon cable |
May 17, 1988 |
| A single mode optical fiber ribbon cable is disclosed. In preferred embodiments, the cable comprises a filling compound having a critical yield stress less than about 70 Pa at 20.degree. C. and/or fibers having a coating that comrises a low modulus (less than about 1.5.multidot.10.sup.6 |

Manufacture of concentric coatings for fiber waveguides |
December 14, 1982 |
| The forward scattering pattern from a transversely-illuminated polymer-coated optical fiber can be used to insure well-centered coatings on optical fibers. A simple interpretation of the scattering pattern provides an error signal to guide compensatory coating cup alignment. For poly |

Methods of and apparatus for organizing fiber lightguides into a planar array |
September 15, 1981 |
| In order to organize a plurality of fiber lightguides (33--33) into a planar array (40), so that they can be bonded together between two tapes (34--34) to form a ribbon (32), the fiber lightguides are payed out from individual supply spools (51--51) and advanced toward a takeup (43). |

Coatings for fiber waveguides |
April 3, 1979 |
| Microbending loss is reduced and abrasion protection is afforded for optical fibers by relatively thick polymer coatings characterized in part by a preferred elastic tensile modulus and cold flow property. The coating process uses rapid cooling of a liquid application to promote rapid |
