1490 nmNanometer, 1577 nm, and 1610 nm.
850 nmNanometer, 980 nm, and 1300 nm.
1310 nmNanometer and 1550 nm. - CORRECT
ANSWER ✔️ 1310 nmNanometer and 1550 nm.
,Which class of optical transmitters is the safest for the
human eye?
Class 3.
Class 4.
Class 1.

What is unique to a fiber break locator?
It requires an expert operator to operate it properly. It is
the least expensive type of OTDROptical time domain
reflectometer.
It utilizes the most complex display and controls. It
typically comes with several lasers, all operating at
different wavelengths. - CORRECT ANSWER ✔️ It is the
least expensive type of OTDROptical time domain
reflectometer.
Which of the following is an additional option for a
fullfeature OTDROptical time domain reflectometer:
ACAlternating current-only operations.
CRTCathode ray tube.
DWDMDense wavelength division multiplexing.
,Internal printers. - CORRECT ANSWER
✔️ DWDMDense
wavelength division multiplexing.
Which of the following is true regarding reflections in an
optical fiber?
As light passes through two materials with different
refraction indexes, the small portion of reflected light is
called an incident reflection.
The backscatter scattering and absorption effects subtract
from the attenuation of the optical fiber.
Microscopic density fluctuations, impurities, and structural
imperfections in the fiber cause Rayleigh scattering.
Fresnel reflection does not occur at the end of the optical
fiber with a subtle glass-to-air
surface. - CORRECT
ANSWER Microscopic density fluctuations,
✔️ impurities,
and structural imperfections in the fiber cause Rayleigh
scattering.
What is an RTURemote test unit characteristic?
It is the third generation of OTDRsOptical time domain
reflectometer.
, It is only used to monitor optical fiber at splice points. It
measures the optical cable from the terminating point on
the network.
It monitors optical fiber from the headend or other key
points in a network. - CORRECT ANSWER ✔️ It
monitors
optical fiber from the headend or other key points in a
network.
What do OTDROptical time domain reflectometer displays
and controls encompass?
Imaging in real time, which implies that the laser is
sporadically pulsing and that the operator cannot see what
is occurring along the fiber at that moment.
An averaging function, which is the least common method
of making attenuation measurements and is the least
accurate.
Task options, which include range, pulse width,
wavelength, measuring mode, backscatter coefficient, and
index of refraction.
Pulse widths that can be measured only in time units but
not in distance units. - CORRECT ANSWER ✔️ Task
options, which include range, pulse width, wavelength,
measuring mode, backscatter coefficient, and index of
refraction.
