Beschreibung
Zusammenfassung:	A tuning head for use with a variable capacitor includes a coupler having a gap, a first optical fiber operatively coupled to the coupler, and a second optical fiber operatively coupled to the coupler. The first and second optical fibers are optically coupled across the gap when the gap is not obstructed. The tuning head further includes an obstruction member that is movable with respect to the coupler and is adapted to fit within the gap to selectively obstruct said optical coupling of said first and second optical fibers. A movement mechanism is also provided to create relative motion between said obstruction member and said coupler.
