OPTICAL CONNECTOR
To access the optical connectors, grasp a top corner of the instrument,
and pull off the cover. Do this on both sides of the instrument.
Each optical port is mounted on a swivel, which allows the connector
to be angled outwards for accessibility, and then pushed back and
covered with the snap cover to provide dirt and drop protection.
Different styles of standard and optional connector adaptors can be
easily fitted by the user.
The supplied standard connector adaptors have ceramic sleeves to
avoid connector metal dust contamination.
CAUTION! Do not use damaged or incompatible connector adaptors.
When not in use, keep the test ports and connectors covered. To
minimize connectors wear, instrument can be stored without removing
the test leads. Never touch connector tips with your fingers, since body
oils and dirt can impair its performance.
WARNING! Remove batteries before using a microscope to inspect
instrument connectors.
Power Meter port:
This port can be used with both PC and APC connector styles.
Bare fiber adaptors must achieve fiber eccentricity of ± 100 microns,
and an end tolerance of ± 300 microns relative to the ferrule end.
Preferred bare fiber adaptors consist of a connector with fiber retention
device or other end stop.
For regular work with bare fibers, it is preferable to use an alternative
arrangement such as a multimode pigtail with a v-groove or
mechanical splice.
CAUTION! Do not scratch the detector lens with glass fiber end when
using bare fiber adaptors, or the instrument will be permanently
damaged.
