Systems and methods for measuring a cleave angle of an optical fiber

A method for measuring a cleave angle of a plurality of optical fibers, the method comprising:

• providing a cleave angle measurement system, wherein the cleave angle measurement system comprises:
• a first optical fiber channel;
• a second optical fiber channel;
• an image sensor;
• a light source;
• and
• a beam splitter disposed between the light source and the first and second optical fiber channels;
• providing the plurality of optical fibers, wherein:
• the plurality of optical fibers comprises a first optical fiber having a first cleaved end and a second optical fiber having a second cleaved end;
• and
• the first cleaved end and the second cleaved end are positioned toward the light source;
• determining an optical center for the image sensor;
• transmitting a first wavelength from the light source to the first cleaved end of the first optical fiber through the beam splitter;
• generating a specular reflection from the first cleaved end of the first optical fiber by reflecting the first wavelength off of the first cleaved end of the first optical fiber to the beam splitter;
• reflecting the first wavelength off of the beam splitter and to the image sensor;
• determining a location of the specular reflection on the image sensor;
• determining, a first cleave angle for the first cleaved end based on the location of the specular reflection and the optical center of the image sensor;
• transmitting a second wavelength from the light source to the second cleaved end of the second optical fiber through the beam splitter;
• reflecting the second wavelength off of the second cleaved end of the second optical fiber to the beam splitter;
• reflecting the second wavelength off of the beam splitter and to the image sensor;
• and
• determining, based on the second wavelength reflected off of the beam splitter and to the image sensor, a second cleave angle for the second cleaved end, wherein the first wavelength is different from the second wavelength.
