Advantages: no special tool required.
This shell of this type of plug is
provided with an integrated strain relief.
The fiber optic cable is clamped
securely when you clip the two sections
of the shell together.
This system can be used to prepare
simplex and duplex plugs. You can
assemble a simplex plug by clipping the
two sections of a shell together and a
duplex plug by clipping two plugs
together.
Disadvantages: no protection against
polarity reversal.
These plugs can be inserted in two
positions. Please check the polarity
when you have turned on the power.
The light emitting fiber is the fiber for
reception.
Assembling a plug:
2 complete plugs are required to as-
semble a duplex plug. Separate the two
cores for a distance of app. 5cm. Use a
stripper to remove the protection cover
so that app. 7mm of the fiber is visible.
Insert the two cores into the plug so
that the ends of the fiber optic cable
protrude at the front. Keep an eye on
the polarity of the cores (s.a.).
Cutting and polishing the ends of the FO cable
Cut protruding fiber using a knife so
that app. 1.5mm are still visible. Polish
the ends to a flat surface using the HP
polishing set (HP order no.:HFBR-
4593).
Insert the plug into the polishing tool
and polish the fiber to achieve a plane
surface as shown in the figure. The
instructions that are included with the
set contain a detailed description of the
required procedure.
