Abstract

This adjustable switch operates to switchably align fiber-optic communication channels without the need for precision parts and without requiring tight tolerances on fiber channel diameters. The switch is illustrated in a double-pole, double-throw configuration, but the basic principles are readily extended to single-pole, single-throw, or single-pole, double-throw configurations.

Fiber Optic Switch with Adjustable Alignment

This adjustable switch operates to switchably align fiber-optic communication channels without the need for precision parts and without requiring tight tolerances on fiber channel diameters. The switch is illustrated in a double-pole, double-throw configuration, but the basic principles are readily extended to single-pole, single-throw, or single-pole, double-throw configurations.

As shown in the top view of Fig. 1, the switch comprises a main body portion 1, several input fiber channels 2 (in this case, three channels) and several output fiber channels 3 (in this case, two channels). The input fiber channels are adjustably secured to the main body 1 by the adjustable input fastener 4. The output fibers 3 are secured adjustably to an output fastener 5 which connects to a shaft 6 displaceable by solenoid 7.

When the solenoid is inactive, as represented in the top view of Fig. 1 and the associated sectional end view of Fig. 2 (taken along line AA in Fig. 1), shaft 6 and output fastener 5 are extended to the indicated position by operation of spring 8, and fiber input channels 2a and 2b are respectively aligned with fiber output channels 3a and 3b. When the solenoid is electrically operated, the spring is compressed and input fibers 2b and 2c are respectively aligned with output fibers 3a and 3b, as shown in the top view of Fig. 3 and the respective sectional end view of Fig. 4 (taken along the same line AA).
