Abstract
The invention relates to an optical fiber ribbon for a skeleton optical cable and a manufacturing method thereof. The optical fiber ribbon comprises optical fibers and ribbon combining coatings, resin coatings are arranged on the two sides of the optical fiber ribbon, and notches are formed in the ribbon combining coatings. The manufacturing method of the optical fiber ribbon comprises the following steps: 1, paying off optical fibers through a pay-off rack, and arranging the optical fibers side by side through a guide wheel to obtain an optical fiber bundle; step 2, introducing the optical fiber bundle into a new branched and pressure-measuring-resistant parallel eye model through a guide wheel; and 3, coating the outer side of the optical fiber bundle with a resin coating, and curing in a UV lamp box in which a UV lamp is arranged to obtain the optical fiber ribbon of the skeleton optical cable. According to the optical cable, the notches are formed, so that the optical fiber ribbons are easy to separate at the notches, the resin coatings increase the side pressure resistance effect, the fiber core spacing can ensure that the optical fiber ribbons can be divided into required subunits and can also ensure that the optical fiber ribbons can be welded with common optical fiber ribbons if the optical fiber ribbons are not branched, the optical cable laying efficiency is improved, and the laying cost is reduced. The production and manufacturing method adopts a one-time coating and curing forming process, so that the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of optical fiber ribbons, in particular to an optical fiber ribbon used for a skeleton optical cable and a manufacturing method thereof. Background technique [0002] Skeleton-type optical cable is an optical cable formed by inserting a primary-coated optical fiber into a groove of a spiral plastic skeleton with a strength member. The material of the skeleton, the manufacturing process, the pitch of the helix, the shape and size of the groove, and the finish all have a great impact on the performance of the fiber. The lateral pressure resistance and branching performance of the skeleton optical cable is an important aspect of the mechanical performance of the optical cable. There are requirements for the lateral pressure resistance of the optical cable in various optical cable standards. changes in the additional attenuation of the fiber and whether the outer jacket is cracked. The lateral pressure protect...
