Chapter 4 Fiberoptic Interface
The fibers can be damaged by coiling the cable up too tightly. If left in a tight
coil for longer than a week, the fibers are likely to develop longitudinal
fractures that will not be detectable. These fractures in the fiber will cause
light leakage, resulting in a weaker signal. The Fiberoptic cables should be
stored by placing them loosely within the netting compartment on the
instrument or on the Fiberoptic spool.
Tips on care for the Fiberoptic cable:
•
Do not pull or hang the spectroradiometer by the Fiberoptic cable.
•
Do not use wires, ties, or clamps to tightly attach the Fiberoptic cable to
objects, this may pinch or penetrate the protective jacket thereby
damaging the fibers inside.
•
Avoid whipping the Fiberoptic cable, dropping it, or slamming it into
objects, this can cause fractures to the glass fibers.
•
Avoid twisting the Fiberoptic cable, such forces may cause fractures to
fibers.
While the tip of the Fiberoptic cable is not particularly susceptible to damage,
a tip cover is recommended to protect against abrasion and exposure to
contamination. Replacement covers can be made by cutting pieces of
eighth-inch shrink tubing to about 1.5" lengths and shrinking them onto the
fiber cable tip. They will slide on and off the cable easily.
The loss in response is further amplified when “jumper” cables are utilized.
Jumper cables are Fiberoptic cables that can be attached to the fixed cable via
an SMA adapter. The loss on the jumpers is largely due to the attenuation at
the junction between the built-in cable and the jumper.

LED Check for Fiberoptic Cable
The FieldSpec spectroradiometer allows you to perform a visual verification
of the Fiberoptic cable using built-in LEDs, a magnifier placed on the
Fiberoptic cable, and the
Fiber Check
software.
WARNING!
The
Fiber Check
utility produces rapid flashing lights in the SWIR 1
and 2 region's optical fibers. If you are susceptible to epileptic seizures,
exercise caution or avoid using the
Fiber Check
utility.
Step 1
Remove any fore optic accessories from the spectrometer’s Fiberoptic cable.
Step 2
Attach the magnifier to the end of the Fiberoptic cable, as shown in
.
