Apparatus and method for selecting and passing an optical wavelength from an aggregate optical signal

An optical wavelength selector, comprising:

• a first housing;
• an optical input adapter coupled to the first housing;
• a second housing;
• a plurality of selectable optical filters disposed between the first housing and the second housing;
• wherein the optical input adapter, the first housing, the second housing and a selected one of the plurality of selectable optical filters form an optical signal path.

An optical wavelength selector comprising:

• a first housing;
• an optical input adapter coupled to the first housing;
• a second housing;
• a plurality of selectable optical filters;
• and
• a filter disk forming a concentric hole, disposed between the first housing and the second housing;
• wherein the plurality of selectable optical filters is disposed on a circular surface of the filter disk equally spaced around a concentric circle adjacent to the concentric inner hole;
• and
• the concentric hole of the filter disk is positioned around a hub allowing the filter disk to rotate such that each of the selectable optical filters can be selectively positioned in an optical signal path.
