Abstract

The invention relates to a method for easily stripping optical fibers or optical fiber ribbons in optical fiber bundles and a silicone oil coating device. The method comprises the steps that a plurality of optical fibers or optical fiber ribbons penetrate through sponges with waterborne silicone oil respectively to form silicone oil layers, viscosity of the silicone oil is maintained at 300-600mpa.s under 25 DEG C, the density of the silicon oil is maintained at 1.01-1.03g / cm at 25 EDG C, the optical fibers or optical fiber ribbons with waterborne silicon oil layers are bonded through resin to form uncured optical fiber bundles, then the uncured optical fiber bundles are photo-cured, and the waterborne silicon oil layers are gasified to form strippable clearances. The silicone oil coating device comprises the sponges, an oil tank, a cover plate and the waterborne silicon oil. The center of the oil tank protrudes, and an annular slot channel for storing the silicon oil is formed in the periphery of the oil tank. The top of the protrusion is higher than the liquid level of the silicon oil in the slot channel, the sponges cover the space formed between the protruding top and the cover plate, and at least a part of the falling portion of the sponges extend below the stored oil liquid level in the oil storage groove. The method has the advantages that stripping of the optical fibers or the optical fiber ribbons is easy.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a method for making optical fibers or optical fibers in an optical fiber bundle easy to peel off and a device for coating silicon oil. Background technique [0002] With the rapid development of the communication industry, the demand for networks is increasing day by day, and the demand for large core count optical cables is increasing. However, the optical fiber ribbon can generally only be made of 12 cores, and 12 optical fibers of different colors are arranged side by side and cured by UV resin to form a figure 1 The fibers shown are tied together. If the number of fiber cores exceeds 12, fibers of the same color will appear in the same fiber ribbon, which is difficult to distinguish. Therefore, the number of cores of the optical fiber ribbon is limited by the color of the optical fiber. In order to obtain more optical fibers and facilitate stripping, the current opt...
