）
5
、
Focus the microscope onto the connector surface;
6
、
Use a light source to illuminate the face of the fiber connector so that the
light is reflected off the surface of the endface. This is achieved if you see a
bright golden shine from the QBH connector endface.
7
、
Inspect the endface surface carefully. Contamination will lead to dark
spots/burns on the surface and possibly damage to the fiber and/or laser. If
contamination is visible on the endface, cleaning is necessary.
8
、
Take out the cap and sleeve, then connect the fiber connector with the cutting
head quickly and fasten them. (Place the cap face down on a clean surface or a
lint-free wipe.)
