With today's ultra-fast transmission of data
between computers in homes and offices, how you wire a premise
will determine if you have the capabilities to match the requirements
demanded of your system. Typically, you will be running unshielded
twisted-pair (UTP) cable throughout your installation and
will need to determine what kind of data throughput and speeds
you require.
There are three categories that have been established for
UTP cables and their respective connecting hardware. The three
categories are:
• Category 3 - typically
used for voice and data transmission up to 16MHz and 10
Mbps such as 10Base-T Ethernet
• Category 4 - With characteristics
specified up to 26 MHz, they are used for voice and data
transmission rates up to 16 Mbps
• Category 5 - When requirements
are specified at 100 MHz and transmission rates of 100 Mbps,
this is your category. This category would be typical for
an installation of 100base-X
• Enhanced Category 5 - When you
want to be prepared for tomorrow's applications, the characteristics
also provide 100 MHz for Fast Ethernet and 155 Mbps ATM
applications
Some Helpful Terms:
• Backbone - A portion
of a network that provides the transport facilities to route
information from source to destination
• Broadband - A transmission technique
that allows multiple signals to be carried simultaneously
• Coaxial Cable - Cable with an inner
conductor surrounded by an insulator and an outer shield.
Used in broadband applications such as cable television
• Ethernet - A type of local area
network (LAN) using coaxial cable at speeds of 10 Mbps
• Fiber Optic Cable - Glass or plastic
fibers that are used to carry digital light signals. They
are used to support transmission speeds around 100 Mbps
• Modem - Specifically, "modulate,
de-modulate". A device that is able to convert analog
signals into digital signals for transmission over long
distances
