Multi-optical-fiber port platform and mfg. method

Abstract

The invention provides the multi-optical port table including the insert core and the optical fiber bundle which the space between the many optical fibers is the sub-micron grade. The method includes: first to remove the covered layer of the optical fiber and cover the heat-shrinkable sleeving on it, the overlapping region is coated with the optical hot setting adhesive; then to heat the heat-shrinkable sleeving until the space between the optical fiber is sub-micron grade; it removes the heat-shrinkable sleeving after cooling it and inserts it into the insert core and fixes it by the ultraviolet glue or the optical hot setting adhesive to construct the tail fiber of the multi-optical fiber; the ultraviolet glue can instead the optical hot setting adhesive, so it can be solidified by the violet solidifying lamp. Last to polish or cut the tail fiber of the optical fiber bundle to construct the multi-optical port table. The invention has the high reliability and small size, but cost little.

Description

technical field [0001] The invention relates to an optical fiber port, in particular to a multi-fiber port platform and a manufacturing method thereof. Background technique [0002] For new applications and requirements, especially with the advent of the fiber-to-the-home, building, curb and desktop (FTTX) era, under the premise of maintaining good reliability, the new multi-fiber system equipment is obviously moving towards lower The development of technology cost and smaller volume requires that the multi-fiber ports constituting the new system equipment should be designed with good reliability, low cost and small volume. [0003] There are generally three known existing methods for constructing multi-fiber ports and the multi-fiber ports formed by this method. The first is to construct a multi-fiber port by placing each optical fiber in a high-precision glass capillary. The fiber port constructed by this scheme can provide a limited number of ports. Generally, only three...

Problems solved by technology

The first is to construct a multi-fiber port by placing each optical fiber in a high-precision glass capillary. The fiber port constructed by this scheme can provide a limited number of ports. Generally, only three-fiber ports can be provided. When applied to four For optical fiber or above, the existing precision processing device cannot meet the practical requirements because it cannot meet the processing accuracy required by the capillary hole

The second solution is to use high-precision glass, silicon V-shaped grooves or polymer square ferrules to construct multi-fiber ports. Since each optical fiber is arranged in the V-shaped groove or polymer square ferrule, its arrangement is Linear arrangement structure, when used in many systems that require micro-optical components such as lenses, because its inherent fiber arrangement structur...
