Abstract

This article describes a dial-operated mechanism for shifting parallel optical fibers from one set of V-grooves to a laterally displaced set of V-grooves. Referring to Fig. 1, a fiber carrier 8 has a circular head 10 with a set of openings 12 for the shiftable fibers. The head 10 is connected to a guide pin 14 through a connecting rod 16. A dial 18 includes an eccentric opening 20 for receiving the head 10. Dial 18 includes a slot 22 which extends half-way about its perimeter. The connecting rod 16 extends through the slot 22. Carrier 8 and dial 18 are assembled in a base 23 including a circular recess 24 having an opening 26 for the connecting rod 16. The guide pin 14 is received within slots 28. The base 23 includes V-grooves 30 for fixed position fibers.

Optical Fiber Switch

This article describes a dial-operated mechanism for shifting parallel optical fibers from one set of V-grooves to a laterally displaced set of V-grooves. Referring to Fig. 1, a fiber carrier 8 has a circular head 10 with a set of openings 12 for the shiftable fibers. The head 10 is connected to a guide pin 14 through a connecting rod 16. A dial 18 includes an eccentric opening 20 for receiving the head 10. Dial 18 includes a slot 22 which extends half-way about its perimeter. The connecting rod 16 extends through the slot 22. Carrier 8 and dial 18 are assembled in a base 23 including a circular recess 24 having an opening 26 for the connecting rod 16. The guide pin 14 is received within slots 28. The base 23 includes V-grooves 30 for fixed position fibers.

Referring to Fig. 2, when the dial 18 is in position 1, the circular head 10 is at its left-most position. In this position, the fibers 12 are aligned with a first set of V-grooves in the base 23. To shift the fibers, the dial 18 is rotated in the direction indicated by arrow 32. Head 10 moves along an arcuate locus. When the dial 18 has been rotated 180o to position 2, the fibers 12 are seated in a second set of V-grooves. The distance traversed by the fibers is determined by the degree of eccentricity of the opening for head 10 within dial 18.
