Short for Category 5, Cat5E cable is network cabling that consists of four twisted pairs of copper wire terminated by RJ45 connectors. Cat 5 cabling supports frequencies up to 100 MHz and speeds up to 1000 Mbps. It can be used for ATM, token ring, 1000Base-T, 100Base-T, and 10Base-T networking. Cat 5e cable runs should be limited to a maximum length of 328 feet (100 meters)
Currently Cat5e has replaced Cat5 as the industry standard for data cablimg communication and is rated up to 350 Mhz. Computers hooked up to a LAN are connected using Cat 5e cables, so if you're on a LAN, most likely the cable running out of the back of your PC is Category 5.
Cat5e cable is known as a twisted pair cable and comes in either solid or stranded types. Solid CAT5ecable supports long cable runs and is designed for fixed cabling situations like homes, offices, and buildings. Stranded CAT5E cable is more pliable and better suited for shorter-distances. Stranded CAT5 cable is commonly used for patch cables or crossover cables.
Cat 5 is based on the EIA/TIA 568 Commercial Building Telecommunications Wiring Standard developed by the Electronics Industries Association as requested by the Computer Communications Industry Association in 1985.
Short for Category 6,
Cat6cable is network cabling that
consists of four twisted pairs of copper wire terminated
by RJ45 connectors. Cat 6 cabling supports frequencies
up to 550 MHz and speeds up to 1000 Mbps. It can be used
for High Speed LAN's, token ring, 1000Base-T, 100Base-T,
and 10Base-T networking.

We Have received many requests from our customers for information on how to make
a Category 6 cable. So below we will discuss the basic instructions for creating
your own CAT6 patch
cables. We hope you find the instructions informative
Strip the cables Jacket back one full inch.
Untwist the wires back to within 1/8" of the jacket.
Arrange the wires in the order in which you want to crimp them. You can
choose from either the 568-A or 568-B wiring methods, however the 568-A is
the most commonly used.
Grasp the wires firmly, between your thumb and forefinger, flatten them,
and even wiggle them a bit, to take out the curliness, (concentrate your
efforts on the bottom 1/2") the wires must lay flat and together, aligned as
close as possible.
While holding the wires firmly, cut off the the wires 1/2" from the
cables jacket (Cut the wires with some sharp
or even high quality scissors, avoid wire cutters that flatten the ends of
the wires insulating material, this makes stuffing the wires very
Stuff the wires into the connector, making sure the wires stay lined up.
Push moderately hard to assure that all of the wires have reached the end of
the connector. Be sure that the cable jacket goes into the back of the
connector by about 3/16".
Place the connector into a
and squeeze hard so that the handle reaches it's full swing.
Repeat the process on the other end. For a straight through cable, use
the same wiring.

Fiber Opticcable employs photons for the transmission of digital signals. A
fiber optic cable
consists of a strand of pure glass a little larger than a human hair. Photons
pass through the glass with negligible resistance. The glass is so clear that,
according to Michael Coden of Codenoll Technologies Corporation (a major fiber
vendor), “a 3-mile-thick fiber optic window would give you the same view as a
1/8-inch-thick plate glass window.” The optic core of
fiber optic cable
is pure silicon dioxide. It makes for good tricks. You can wrap it around
yourself, then shine a light in one end and see that light on the other end.
Copper cable, on the other hand, is subject to problems with attenuation,
capacitance, and crosstalk.
Fiber optic cable
is resistant to electromagnetic interference and generates no radiation of its
own. This last point is important in locations where high levels of security
must be maintained. Copper wire radiates energy that can be monitored. In
contrast, taps in
fiber optic cable are easily detected. fiber optic cable also
extends to much longer distances than copper cable.
Information is transmitted through
fiber optic cable
by pulsing laser light. The electronic 1s and 0s of computers are converted to
optically coded 1s and 0s. A light-emitting diode on one end of the cable then
flashes those signals down the cable. At the other end, a simple photodetector
collects the light and converts it back to electrical signals for transmission
over copper cable networks.
Figure 1-A illustrates the
fiber optic cable
structure. The core is the transparent glass (or plastic) component of the
cable. Light shines through it from one end to the other. The cladding, which is
a glass sheath that surrounds the core, is a key component. Like a mirror, it
reflects light back into the core. As light passes through the cable, its rays
bounce off the cladding in different ways as shown in Figure 1-B.
Telephone wiring for a phone outlet is typically either 1, 2 or 3 pairs (2, 4,
or 6 conductor). Most cable nowadays is UTP (unshielded twisted pair). There may
be instances where you may need to connect to or transpose from the old “quad”
cable. The diagram below provides the transposition between these standards.
Pair 1 (T1 & R1):
Usually the primary dial tone or talk circuit is wired to the center two pins
(pins 3 & 4) and is the white/blue and blue/white pair (AKA: T1 & R1 – tip 1 and
ring 1). A standard single line phone draws dial tone from these center pins.
Pair 2 (T2 & R2):
The secondary circuit is wired to the two pins (pins 2 & 5) directly to the
side of the center pins and is the white/orange and orange/white pair (AKA: T2 &
R2 – tip 2 and ring 2). Depending on the application, the secondary circuit can
either be the 2nd dial tone line on a two line phone, or the data/control
circuit for an electronic key phone.
Pair 3 (T3 & R3):
The third circuit is wired to the two pins (pins 1 & 6) on the outside and is
the white/green and green/white pair (AKA: T3 & R3 – tip 3 and ring 3).
Depending on the application, the third circuit can either be the 3rd dial tone
line on a three line phone or an accessory circuit for an electronic key phone.
Tip & Ring:
In telephony the terms that represent the conductors that compromise a
circuit are known as “tip and ring”. These terms stem from the early days of
telephony when operators made telephone connections using ¼” phono plugs similar
to those used today for stereo headphones. The old systems also carried a third
wire which was a ground. The “Tip” was the tip of the plug and was the positive
(+) side of the circuit. The “Ring” was a conductive ring right behind the tip
of the plug and was the negative (-) side of the circuit. Right behind the ring
was the “Sleeve” which was the ground connection.
USOC (Universal Service Ordering Codes):
In the old days of telephony, USOC (pronounced U-sock) standards were used to
simplify and standardize the various different wiring schemes for modular jacks.
RJ (RJ-11, RJ-45 Etc.):
The USOC standards consisted of many different Registered Jack Configurations
which were abbreviated as “RJ” and had designations like RJ-11, RJ-12, etc.
Today we still refer to modular jacks in the RJ designations but rarely use them
to refer to a wiring standard that they were originally intended for. Even
though it is technically incorrect, popular terminology today for the terms
RJ-11, 12 or 14 refer to a 6 pin jack and RJ-45 refers to an 8 pin jack.
