BENEFITS OF FIBER OPTICS

Optical fiber systems have many advantages over metallic-based communication systems. These
advantages include:

• Long-distance signal transmission

The low attenuation and superior signal integrity found in optical systems allow much
longer intervals of signal transmission than metallic-based systems. While single-line,voice-grade copper systems longer than a couple of kilometers (1.2 miles) require in-line
signal for satisfactory performance, it is not unusual for optical systems to go over
100 kilometers (km), or about 62 miles, with no active or passive processing.

• Large bandwidth, light weight, and small diameter

Today’s applications require an ever-increasing amount of bandwidth. Consequently, it is
important to consider the space constraints of many end users. It is commonplace to install
new cabling within existing duct systems or conduit. The relatively small diameter and light
weight of optical cable make such installations easy and practical, saving valuable conduit
space in these environments.

• Nonconductivity

Another advantage of optical fibers is their dielectric nature. Since optical fiber has no
metallic components, it can be installed in areas with electromagnetic interference (EMI),
including radio frequency interference (RFI). Areas with high EMI include utility lines,
power-carrying lines, and railroad tracks. All-dielectric cables are also ideal for areas of
high lightning-strike incidence.

• Security

Unlike metallic-based systems,the dielectric nature of optical fiber makes it impossible to
remotely detect the signal being transmitted within the cable. The only way to do so is by
accessing the optical fiber. Accessing the fiber requires intervention that is easily detectable
by security surveillance. These circumstances make fiber extremely attractive to
governmental bodies, banks, and others with major security concerns.

• Designed for future applications needs

Fiber optics is affordable today, as electronics prices fall and optical cable pricing remains
low. In many cases, fiber solutions are less costly than copper. As bandwidth demands
increase rapidly with technological advances, fiber will continue to play a vital role in the
long-term success of telecommunication.
