The optical fibers are made of
glass or plastic. Most of them are approximately the diameter of a human hair
and can be many miles long. Light is transmitted along the center of the fiber
from one end to the other and a signal can be imposed. Fiber optic systems are
superior to metal conductors in many applications. Its biggest advantage is
bandwidth. Due to the wavelength of the light, it is possible to transmit a
signal that contains much more information than is possible with a metal
conductor, even a coaxial conductor. Other benefits include:
• Electrical insulation: optical
fibers do not need a ground connection. Both the transmitter and the receiver
are isolated from each other and therefore free from ground loop problems. In
addition, there is no danger of sparks or electric shock.
• Without EMI: optical fibers are
immune to electromagnetic interference (EMI) and do not emit radiation to cause
other interference.
• Reduced power loss: this allows
longer cables and fewer repeater amplifiers.
• Lighter and smaller: the fiber
weighs less and requires less space than metal conductors with an equivalent
signal transmission capacity.
Copper wire is approximately 13
times heavier. Fiber is also easier to install and requires less space in the
duct.
applications
Some of the main areas of application
for optical fibers are:
• Communications: voice, data and
video transmission are the most common uses of optical fibers and include:
- Telecommunications
- Local area networks (LAN)
- Industrial control systems.
- Avionic systems
- Command, control and military
communications systems.
• Detection: the optical fiber
can be used to send light from a remote source to a detector to obtain
information on pressure, temperature or spectrum. Fiber can also be used
directly as a transducer to measure a variety of environmental effects, such as
voltage, pressure, electrical resistance and pH. Environmental changes affect
light intensity, phase and / or polarization in ways that can be detected at
the other end of the fiber.
• Power supply: Optical fibers
can offer remarkably high power levels for activities such as laser cutting,
welding, marking and perforation.
• Illumination: a set of fibers
together with a light source at one end can illuminate areas that are difficult
to reach, for example, within the human body, together with an endoscope. In
addition, they can be used as a display signal or simply as decorative
lighting.
Pay for experience level for
fiber optic technician -
A basic level fiber optic
technician with less than 1 year of experience can expect to earn an average
total compensation (including tips, bonuses and overtime allowance) of $ 16.64
based on 47 salaries. A professional fiber optic technician with 1-4 years of
experience earns an average total compensation of $ 18.84 based on 349
salaries. A mid-career fiber optic technician with 5-9 years of experience
earns an average total compensation of $ 21.77 based on 228 salaries. An
experienced fiber optic technician with 10-19 years of experience earns an
average total compensation of $ 25.30 based on 168 salaries. At the end of
their career (20 years and more),fiber optic engineer salary / employees earn an average total compensation
of $ 27.
