3.3. Protective end cap of output cable and using description
3.3.1 Types of protective end caps and factory status
For multi-module high-power fiber lasers, the output cable type used is QBH/QD/QP output optical
cable. There are two types of protective end caps in the machine, as shown in the figure. Type A end cap:
It is assembled on the output optical cable when it leaves the factory. The end cap is equipped with a
protective window to ensure the cleanliness of the end cap (or crystal) during transportation.
Type B end cap: It is attached to the packaging accessories and is generally packed in a lamination
box. The end cap is not equipped with a protective window, which is used to prevent the end cap from
being damaged when the optical cable is loaded with the cutting head (or welding head).

some models need to replace the protective end cap. Please refer to the " Cleaning Instructions for the
Output Optical Cable Before Installation " to clean the output optical cable and the protective end cap.
