Bend Insensitive Fiber Cable- Get "Tied Up' in the New Technolgy!
American Tele Data now carries Draka Communications new family of Bend Insensitive fiber cables designed and manufactured to provide the installer forgiveness, speed and low connector insertion loss during installation. Draka's ezInterconnect cables with BendBright-XS fiber inside give installers peace of mind by taking away the historical barriers encountered while routing fiber cables into and through an apartment, condo, high rise building, or multi-tenant business center. From the onset of using fiber optic cable for installations- there has always been the issue of fiber 'bend radius" whic has to be closely montiroed when designing fiber runs and fiber networks. Now with Bend Insensitive fiber and bend insensitive optical cable the 'careless" type of data communications installer will still be able to get the proper performance readings on his opwer meter/light source or OTDR.Bedn Insensitive Fiber is not designed to be puilled into "knots as the picture above illustrates- it is merely an illustration to make a point on the durability and flexibility of bed insensitve optic cable.
How can Draka help our customers do more, make more, save more, achieve more? Using Bend insensitve fiber cable means creating value for the installer by designing a fiber cable that has a minimum bend radius of only 7.5 mm and handles like copper in the customer premise.

Fiber Optic Cable refers to the complete assembly of fibers, strength members and jacket. Fiber optic cables come in lots of different types, depending on the number of fibers and how and where it will be installed. Choose cable carefully as the choice will affect how easy it is to install, splice or terminate and, most important, what it will cost! We offer COMPLIMENTARY ENGINEERING at no cost for simple questions regarding fiber. For designing fiber networks or FTTH developments please ask for one of our engineers or visit one of our partners at ATEK for further assistance.
Simplex and Zip Cord
Simplex and Zip Cord: Simplex fiber optic cables are one fiber, tight-buffered (coated with a 900 micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use. The jacket is usually 3mm (1/8 in.) diameter. Zipcord is simply two of these joined with a thin web. It's used mostly for patch cord and backplane applications, but zipcord can also be used for desktop connections.
Distribution Cables
Distribution Cables: Distribution fiber optic cables contain several tight-buffered fibers bundled under the same jacket with Kevlar strength members and sometimes fiberglass rod reinforcement to stiffen the cable and prevent kinking. These cables are small in size, and used for short, dry conduit runs, riser and plenum applications. The fibers are double buffered and can be directly terminated, but because their fibers are not individually reinforced, these cables need to be broken out with a "breakout box" or terminated inside a patch panel or junction box.
Breakout Cables
Breakout Cables: Breakout Fiber Optic Cables are made of several simplex cables bundled together. This is a strong, rugged design, but is larger and more expensive than the distribution cables. It is suitable for conduit runs, riser and plenum applications. Because each fiber is individually reinforced, this design allows for quick termination to connectors and does not require patch panels or boxes. Breakout cable can be more economic where fiber count isn't too large and distances too long, because is requires so much less labor to terminate.
Loose Tube Cables
Loose Tube Cables: Loose Tube Fiber Optic cables are composed of several fibers together inside a small plastic tube, which are in turn wound around a central strength member and jacketed, providing a small, high fiber count cable. This type of cable is ideal for outside plant trunking applications, as it can be made with the loose tubes filled with gel or water absorbent powder to prevent harm to the fibers from water. It can be used in conduits, strung overhead or buried directly into the ground. Since the fibers have only a thin buffer coating, they must be carefully handled and protected to prevent damage.
Ribbon Cable
Ribbon Cable: Ribbon Fiber Optic Cables offer the highest packing density, since all the fibers are laid out in rows, typically of 12 fibers, and laid on top of each other. This way 144 fibers only has a cross section of about 1/4 inch or 6 mm! Some cable designs use a "slotted core" with up to 6 of these 144 fiber ribbon assemblies for 864 fibers in one cable! Since it's outside plant cable, it's gel-filled for water blocking.
Armored Fiber Optic Cable
Armored Cable: Armored Fiber Cable is used by the military, industrial applications as in petrochemical, industrial plants including nuclear and Utilities are installed by direct burial in areas where rodents are a problem usually have metal armoring between two jackets to prevent rodent penetration. This means the cable is conductive, so it must be grounded properly.
Aerial Fiber Optic Cable
Aerial Cable: Aerial cables are for outside installation on poles. They can be lashed to a messenger or another cable (common in CATV) or have metal or aramid strength members to make them self supporting.
Even more types are available: every manufacturer has it's own favorites, so it's a good idea to get literature from as many cable makers as possible. And check out the specialty or on-line suppliers like American Tele Data-; often they can save you a bundle by making special cable just for you, even in relative small quantities.

OVER VIEW OF FIBER OPTIC CABLE ADVANTAGES OVER COPPER:•
SPEED: Fiber optic networks operate at high speeds - up into the gigabits
•
BANDWIDTH: large carrying capacity
• DISTANCE: Signals can be transmitted
further without needing to be "refreshed" or strengthened.
•
RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors
or other nearby cables.
• MAINTENANCE: Fiber optic cables costs much less
to maintain.
In
recent years it has become apparent that fiber-optics are steadily replacing copper
wire as an appropriate means of communication signal transmission. They span the
long distances between local phone systems as well as providing the backbone for
many network systems. Other system users include cable television services, university
campuses, office buildings, industrial plants, and electric utility companies.A
fiber-optic system is similar to the copper wire system that fiber-optics is replacing.
The difference is that fiber-optics use light pulses to transmit information down
fiber lines instead of using electronic pulses to transmit information down copper
lines. Looking at the components in a fiber-optic chain will give a better understanding
of how the system works in conjunction with wire based systems.At
one end of the system is a transmitter. This is the place of origin for information
coming on to fiber-optic lines. The transmitter accepts coded electronic pulse
information coming from copper wire. It then processes and translates that information
into equivalently coded light pulses. A light-emitting diode (LED) or an injection-laser
diode (ILD) can be used for generating the light pulses. Using a lens, the light
pulses are funneled into the fiber-optic medium where they transmit themselves
down the line.Think
of a fiber cable in terms of very long cardboard roll (from the inside roll of
paper towel) that is coated with a mirror.
If you shine a flashlight in one
you can see light at the far end - even if bent the roll around a corner.Light
pulses move easily down the fiber-optic line because of a principle known as total
internal reflection. "This principle of total internal reflection states
that when the angle of incidence exceeds a critical value, light cannot get out
of the glass; instead, the light bounces back in. When this principle is applied
to the construction of the fiber-optic strand, it is possible to transmit information
down fiber lines in the form of light pulses.
Multimode cable is made of of
glass fibers, with a common diameters in the 50-to-100 micron range for the light
carry component (the most common size is 62.5). POF is a newer plastic-based cable
which promises performance similar to glass cable on very short runs, but at a
lower cost.Multimode
fiber gives you high bandwidth at high speeds over medium distances. Light waves
are dispersed into numerous paths, or modes, as they travel through the cable's
core typically 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5,
and 100 micrometers. However, in long cable runs (greater than 3000 feet [914.4
ml), multiple paths of light can cause signal distortion at the receiving end,
resulting in an unclear and incomplete data transmission. The use of fiber-optics
was generally not available until 1970 when Corning Glass Works was able to produce
a fiber with a loss of 20 dB/km. It was recognized that optical fiber would be
feasible for telecommunication transmission only if glass could be developed so
pure that attenuation would be 20dB/km or less. That is, 1% of the light would
remain after traveling 1 km. Today's optical fiber attenuation ranges from 0.5dB/km
to 1000dB/km depending on the optical fiber used. Attenuation limits are based
on intended application.The
applications of optical fiber communications have increased at a rapid rate, since
the first commercial installation of a fiber-optic system in 1977. Telephone companies
began early on, replacing their old copper wire systems with optical fiber lines.
Today's telephone companies use optical fiber throughout their system as the backbone
architecture and as the long-distance connection between city phone systems.Cable
television companies have also began integrating fiber-optics into their cable
systems. The trunk lines that connect central offices have generally been replaced
with optical fiber. Some providers have begun experimenting with fiber to the
curb using a fiber/coaxial hybrid. Such a hybrid allows for the integration of
fiber and coaxial at a neighborhood location. This location, called a node, would
provide the optical receiver that converts the light impulses back to electronic
signals. The signals could then be fed to individual homes via coaxial cable.Local
Area Networks (LAN) is a collective group of computers, or computer systems, connected
to each other allowing for shared program software or data bases. Colleges, universities,
office buildings, and industrial plants, just to name a few, all make use of optical
fiber within their LAN systems.
Power
companies are an emerging group that have begun to utilize fiber-optics
in their communication systems. Most power utilities already
have fiber-optic communication systems in use for monitoring
their power grid systems.
