Specifications
circuitry, and receive-level scale.
The Pocket Opto Source is
a single component, a regulated
optical source.
All of these test devices shoot
light into the fiber optic cable at the
varying intensities: 100-micron cable
core: -20-dBm intensity; 62.5 micron:
-23 dBm; and 50 micron: -26 dBm.
The optical receiver and
receive-level circuitry of the Pocket
Fiber Tester and the Fiber Talk’n
Test include an optoelectronic
transducer and active voltage-
divider circuitry. These components
convert the light received into a
voltage, which is then modified
by the receive-level circuitry and
displayed on the testers’ receive-
level LED scale.
The receive-level LED scale,
which is calibrated in -2-dBm steps
from -22 dBm to -40 dBm, shows
you the intensity of light, in dBm,
received by the tester.
Interpreting a tester reading
You can determine the
approximate measurement of
received power of light in the cable
by simply observing the highest
bar illuminated on the tester’s LED
scale. For example, if all bars on
the scale light up to and include the
“28” segment of the bar graph, you
know the measured received power
is at least -28 dBm but less than
-26 dBm, the next highest scale
value (that is, the signal received
is between -28 and -26 dBm).
You would then compare the
difference between the amount of
light sent and the amount received
to immediately know how well your
fiber cable transmits light signals
and to determine its quality.
Tester applications
You can use the Pocket Fiber
Tester or Fiber Talk’n Test in a
variety of measurement modes. Use
a single tester as both transmitter
and receiver to test continuity in a
spool of cable. Or use a single tester
to detect light activity on a particular
cable that you‘re trying to locate
within a bundle of cable.
You can also use two testers
in tandem to check both sides
of duplex cables simultaneously.
Connect one tester to terminals at
the start of the cable, and connect
the other tester to the cable‘s other
end. You can then compare the
measurements for each side of the
duplex cable with the values you
expect.
Want to examine long-distance
cable runs? Well, the Pocket Fiber
Tester can be used with a Pocket
Opto Source to examine such
lengthy runs. In this setup, the
transmitter of the Pocket Opto
Source sends the light signal while
the optical receiver of the Pocket
Fiber Tester measures the signal
loss.
