The invention provides a scheme for attenuating light transmitted through an optical fiber, using an attenuator including a base plate having a series of vertical protrusions extending therefrom and a top plate positioned to close with the base plate. When closed, the base plate and top plate clamp a length of optical fiber between the base plate vertical protrusions and the top plate such that an optical fiber bends around the protrusions. Also provided is an optical attenuator including a rigid base plate having a channeled depression, on one face of the base plate, that includes a nonlinear channel path along at least a portion of the channeled depression. The channeled depression extends from a first point at an edge of the base plate face to a second point at an edge of the base plate face to form a continuous channel path between the first and second edge points. A length of optical fiber can be positioned in the channel path such that bends in the nonlinear channel path producing corresponding bends in the length of optical fiber.

Apparatus and method for the assembly of an optical fiber termination that does not require adhesive applies a selected force characteristic over a selected displacement. The apparatus includes a holder element, a drive element, and a positioning element that directs the relative motion of the holder and drive elements. In operation, the holder element receives a partially assembled optical fiber termination including inner and outer elements and a compressive system. The drive element, guided by the positioning element, provides the force which presses the elements of the termination telescopically together. The telescoping of the two termination elements compresses the compressive system into mechanical engagement with the optical fiber. The pressing force has a limited maximal value to prevent undue stress or damage to the optical fiber.

A fiber optic connector resists signal interruption with a structure that has an inner body, that receives and mounts an optical fiber, and that has an outer body having an axial passage that receives the inner body. The outer body has two sections arranged in axial succession. The outer-body back section mounts a captive element for mechanical coupling with a further optical device with which the connector mates. The forward, second section of the outer body is arranged for limited axial displacement relative to the first section. The connector has structure forming two springs or like resiliently acting elements; one biases the front end of the inner body axially forward relative to the back of the outer body, and the second biases the front of the outer body forward relative to the back section of the outer body.

Apparatus and method for the assembly of an adhesiveless optical fiber termination applies a selected force characteristic over a selected displacement. The apparatus includes a holder element, a drive element, and a positioning element which directs the relative motion of the holder and drive elements. In operation, the holder element receives a partially assembled optical fiber termination including inner and outer portions and a compressive system. The drive element, guided by the positioning element, provides the force which presses the portions of the termination telescopically together. The telescoping of the two components compresses the compressive system into mechanical engagement with the optical fiber.
