A first waveguide holding member has a first transverse surface region and a
first
optical waveguide having an end terminating at the first transverse surface region.
A second waveguide holding member has a second transverse surface region which
confronts the first transverse surface region of the first waveguide holding member
and a second optical waveguide having an end terminating at the second transverse
surface region. A guide member is operatively coupled to the first and second waveguide
holding members and guides the first waveguide holding member in a transverse direction
relative to the second waveguide holding member so as to selectively optically
couple and decouple the ends of the first and second optical waveguides.
