Abstract: A method for making an optical connector support member. The method can be broadly summarized by the following steps: One or more features are partially etched in a monocrystalline substrate to form a template. The features are etched in the substrate to a depth necessary to form the functional portions of the features. An inverse replica is created and then separated from the template. Additional material is bonded to the inverse replica in the regions that correspond to the features that were partially etched in the monocrystalline substrate. The inverse replica with the additional material bonded thereto is then used as a pattern for making a support member. A multi-fiber support member made using the inverse replica described in the foregoing will have one or more features formed therein that correspond to the features etched in the monocrystalline substrate, but are deeper because of the additional material that was bonded to the inverse replica.

Abstract: A fixture for use in a fiber curl measurement assembly has a fiber guide plate upon which are disposed a pair of fiber locating and centering rods which form a V-groove for containing the fiber, which is free to rotate within the groove. A reference plate having a transverse reference edge in space from the downstream end of the V-groove a distance sufficient for fiber curvature to be measured during rotation.

The rotating stage is oriented at a vertical angle to the plane of the rods and V-groove, and the fiber is threaded through a bearing block into the V-groove. The bend thus created in the fiber is such that a downward force is created on the fiber to hold it within the V-groove. Thus, where the rotating stage is rotated by the motor, the fiber within the groove is rotated so that curl measurements may be made.

Abstract: In encapsulating an optocomponent with a plastics material, an MT-connector compatible interface is obtained having bores for guide pins in the wall of the capsule and optical connection surfaces. These bores are obtained from mold cavity guide pins that are used for aligning the optocomponent in a mold cavity in a mold in the molding operation of the encapsulating material on top of the component. In order to achieve a good accuracy in the positioning of the component during the molding operation, the mold guide pins are as short as possible and end directly behind the component where they are supported by projections extending from each mold half. Thus, cavities are created extending straight through the capsule behind the component. The cavities allow that the guide pin bores are cleansed and that material residues are removed after the molding operation. Further, the cavities can be used for spring clamps for retaining the optocomponent capsule at an optical connector having a similar interface.
