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.
