2.4 Insertion Direction Adjustment of Fiber Interface
This article explain the fiber insertion method of the QBH splice.
1. Before use, blow off the dust on the QBH fiber interface and the protective cap with clean gas to
ensure that there is no dust residue at the time of installation.
Note: As shown in Figure 1, when the QBH optical interface is not used, the QBH fiber interface
should not be exposed on the top and bottom, and must be covered with dust cover to keep it
clean inside.
As shown in Figure 2, when the protective cap is not used, the protective cap needs to be sealed
with a clean self-sealing bag so as to avoid dust falling into it.
2. As shown in Figure 3, please align the center hole of the protective cap to the optical fibre splice
and put it on the optical fibre splice. Notice that all the sealing rings on the fiber head are exposed
below the protective cap.
3. As shown in Figure 4, check the red dot to the red dot on QBH first, then align the T-shaped pin slot
on the optical fiber and the red dot to form a line, and insert the optical fiber head with the protective
cap into the QBH optical fiber interface.
Note: It is best to insert the optical fibre splice horizontally to prevent dust from entering the
laser head when inserting the optical fibre splice, insert the fiber head firmly into the bottom to
ensure that the sealing ring on the optical fibre splice is completely sunk into the QBH optical
fibre splice.
