摘要:
A positioning of a plurality of optical fibers 11 is performed by a pair of position regulating members 12a and 12b. Then, the paired position regulating members 12a and 12b are moved along two guide members 13, 13 in such a manner as to have a predetermined distance therebetween. A ribbon support member 15 is placed between the paired position regulating members 12a and 12b in such a way as to support the optical fibers 11. The plurality of optical fibers 11 are held and fixed by the holding members 17a and 17b. Further, the plurality of optical fibers 11 put on the ribbon support member 15 are sandwiched by the ribbon support member 15 and the pressing tool 19 opposed thereto. In a terminal portion structure 110a of a ribbon fiber 10, terminal portions of optical fibers 102 are arranged horizontally in parallel, an adhesive tape is stuck onto at least one of upper and lower surfaces of at least the terminal portions.

摘要:
An optical fiber ribbon includes a plurality of optical fibers encapsulated within a matrix material, where the optical fiber coating(s) and the matrix material(s), and optionally any ink layers thereon, are characterized by compatible chemical and/or physical properties, whereby the fiber coating and matrix and any ink layers therebetween can be reliably stripped from the optical fibers to afford a suitable strip cleanliness. Novel ink formulations that can be used in the making of such fiber optic ribbons, methods of making such ribbons, and their use are also described.
摘要:
According to certain aspects of the present invention, a fiber optic ribbon is disclosed including a plurality of optical fibers arranged in a generally planar configuration, and a matrix disposed generally about the plurality of optical fibers. The matrix has a substantially continuous outer surface and defines an internal discontinuity spaced from the outer surface. The discontinuity weakens the matrix at the discontinuity, thereby forming a preferential tear area. Various options and modifications to the above structure are disclosed. Also, related methods of forming fiber optic ribbons are disclosed.

A process for automatically forming optical shuffles, which included providing a plurality of spools are provided, which are each formed from at least one fiber. The free ends of the fibers are led up to a winding device and fixed to the latter in such a way that the fibers can be wound onto it in one and the same winding direction and lying approximately parallel to one another. The sections of the fibers coming from the spool are combined with one another in groups to form ribbons. A first length section of each ribbon is unwound from the associated spool and wound onto the winding device (input side of the shuffle). After the length section has been unwound, the spools or fiber-guiding devices connected downstream of the spools are reorganized, so that, in a direction running transversely with respect to the unwinding direction, the outgoing fibers assume different positions relative to one another than before. A second length section of all the fibers is unwound from the spools and wound onto the winding device, the fibers coming from one spool crossing the fibers coming from another spool and a shuffle section thus being formed. Finally, on the output side of the shuffle, a further section of ribbons is provided, which can subsequently be provided in groups with plugs.
摘要:
A coated optical fiber includes a fiber coating having an unblended primary portion on the optical fiber, an unblended secondary portion, and a blended portion intermediate the unblended primary and secondary portions. The thickness of the blended portion is greater than or equal to about 10% but less than 100% of the thickness of the fiber coating. An optical fiber ribbon includes a ribbon matrix similarly having an unblended primary portion, an unblended secondary portion, and a blended portion between the unblended primary portion and unblended secondary portion. A method for fabricating a coated optical fiber or optical fiber ribbon includes applying a primary portion material to the optical fiber or plurality of coated optical fibers, and applying a secondary portion material in a manner selected to provide a blend of the primary portion material and the secondary portion material. An applicator apparatus includes means for performing the described steps.

摘要:
An optical fiber drop cable for carrying one or more optical fibers from a curb to a customer premises. The optical fiber drop cable comprises first and second ribbon-like longitudinal support members disposed one atop the other and having one or more optical fibers disposed between them in a longitudinal direction of the first and second ribbon-like longitudinal support members. The first and second ribbon-like longitudinal support members each have first and second edges and inner and outer surfaces. The first edge of the first ribbon-like longitudinal support member is secured to the first edge of the second ribbon-like longitudinal support member and the second edge of the first ribbon-like longitudinal support member is secured to the second edge of the second ribbon-like longitudinal support member. Securing the edges of the first and second ribbon-like members together in this manner obviates the need to extrude an outer jacket for the cable, which decreases manufacturing costs, thereby decreasing the overall cost of the optical fiber drop cable.
摘要:
One or more optical fiber elements each constituted by a coated glass fiber are fed to an over-coating device and an over-coating is applied to the optical fiber elements in a lump, the feeding speed of the optical fiber elements to the over-coating device is made larger than the take-up speed of the over-coated optical fiber onto a take-up reel so as to give longitudinal compression strain to the glass fibers of the over-coated optical fiber. The glass fiber has compression strain of not less than 0.03% to less than 0. 10% in a longitudinal direction thereof at room temperature.
