Patent ID: 8160444

Claim:
An optical wavelength selector, comprising: a housing disposed between an optical cable output connector and an optical power meter configured for removable external connection used to interface the optical cable output connector to the optical power meter; at least one selectable optical filter disposed within said housing in an optical signal path between the optical cable output connector and the optical power meter, said housing comprising an output optical connector which removably mates with an input optical connector of the optical power meter, wherein the at least one selectable optical filter is capable of separating a selected optical signal wavelength component from a plurality of optical signal wavelength components of an aggregate optical signal, wherein the at least one selectable optical filter is manually operable to pass the selected optical signal wavelength from the optical signal output connector through the at least one selectable optical filter, wherein the optical cable output connector is detachably connected to said housing through an optical interface adapter, wherein the at least one selectable optical filter comprises: a 1490 nanometer wavelength optical bandpass filter; a 1550 nanometer wavelength optical bandpass filter; and at least one open air space, wherein the open air space allows passage of an aggregate optical signal, and wherein the optical interface adapter is interchangeable among a group consisting of an SC adapter, an FC adapter, an ST adapter, an LC adapter, and a universal adapter.
