Media Converter Terminology
In today’s modern world and growing bandwidth, it is very important
to stay ahead of the game when it comes to communication. That is where
media converters come in. Here is a list of common media converter “jargon,”
making it easier for novices to learn about the importance of media
converters in modern communication.
What is a Media Converter?
A media converter is a device that receives data signals from one media,
and converts and transmits them to another media. For example, many
older systems transmitted signals through copper cables. Instead, of
replacing your entire network with modern fiber, many people use media
converters to convert signals transmitted on a copper cable to signals
that run on fiber.
EHERNET
What is Ethernet?
Ethernet is a frame-based computer networking technology for local area
networks, otherwise known as LAN. It is the most widespread LAN technology
in use today. It has replaced other LAN standards, such as FDDI , ACCNET,
and Token Ring.
What is an Ethernet Hub?
An Ethernet Hub, otherwise known as a concentrator, is a device that
connects twisted pair or fiber optic Ethernet device together. This
makes them act as a single segment allowing transmission.
What is a Network Switch?
A network switch is often referred to as an “intelligent hub.”
With this in mind, you can understand why most modern Ethernet installations
use a network switch instead of an Ethernet hub.
What is an Optical Fiber?
An optical fiber is a clear, very thin fiber, typically made from glass
or plastic that is used to transmit light or sound.
CABLES
What is a Twisted Pair
A twisted pair is a very common form of wiring cable in which two conductors
are twisted around each other. The purpose of this is to cancel out
electromagnetic interference, which can pick up crosstalk in the Ethernet.
The greater number of twists a twisted pair has, the less crosstalk
in the Ethernet.
What is a Shielded Twisted Pair?
A shielded twisted pair, or STP, is a cable that has a conductive braided
or foil casing around each pair. This offers excellent protection from
crosstalk and interference in the Ethernet. A shielded twisted pair
is much more expensive than a twisted pair. This makes them less desirable
in certain situations.
What is a Screened Shielded Twisted Pair?
A screened shielded twisted pair, or S/STP, is just like a shielded
twisted pair, but with an extra outer braided or foil shield to coaxial
cable. This offers even more protection form crosstalk and other external
interference.
What is an Unshielded Twisted Pair?
An unshielded twisted pair, or UTP, are cables that are not surrounded
by any shielding at all. It is very common for computer networking because
it is highly flexible. It is also the primary wiring for telephone networks.
What is a Foiled Twisted Pair?
A foiled twisted pair, or FTP, is cable that is unshielded. It is surrounded
by an outer foil shield that increases protection from crosstalk and
external interference.
What is a Screened Unshielded Twisted Pair?
A screened unshielded twisted pair, or FTP, is a unshielded twist pair
(UTP) surrounded by an outer foil shield used for extra protection against
external interference.
What is Screened Foiled Twisted Pair?
Screened Foiled Twisted Pair, or S/FTP, is a combination cable with
a combined braided and foil shielding. This, yet again, adds extra protection
from external interference.
IEEE
What is the IEEE?
Pronounced as “eye triple-e,” IEEE stands for the Institute
of Electrical and Electronics Engineers. This is an international nonprofit,
professional organization for the advancement of electricity-related
technology. With 360,000 members in 175 countries, the IEEE is has the
largest technical professional organization worldwide.
What is IEEE 802.3?
Seen in mostly cables, IEEE 802.3 refers to the IEEE standards that
define the physical layer or wired Ethernet.
Hopefully this list was helpful in giving you a head’s up when
researching media converters and how they relate to you or your business.
