Fiber Insertion and Interface Direction Adjustment
In this section, an optical fiber insertion method is described in conjunction with QBH
connector.
First, align the red point at the end of the QBH connector with the red point of the handwheel;
then remove QBH dust proof cover ,the red mark of fiber output end is aligned to QBH red
mark ,insert the fiber interface straight to bottom; Then turn the QBH handwheel clockwise. It is in
place when you hear the "Da" sound, then pull the handwheel up and turn clockwise again. ( see
Figure 3.4 )
When the fiber interface insert into the QBH connector, the red point on fiber is too far away
from the red point on laser head interface, causing an out of alignment insertion, users can refer to
these steps below to adjust the position of fiber interface on laser head for solving the problem. As
shown in Fig. 3.4, loosen the 4 locking screws of the part with a wrench, rotate the QBH interface ,
then tighten the locking screws after the red mark is in place.
