Fiber Optics

Race Communications installs fiber optic for many types of fiber applications, floor
to floor, rack to rack, closet to closet and even building to building if needed and/or a
mixture of all. Don’t forget about our other services like network wiring!!

How fiber works

A fiber optic chain works in the following manner. At one end, the fiber cable is
connected to a transmitter. The transmitter converts electronic pulses into light pulses
and sends the optical signal through the fiber cable. At the other end, the fiber cable is
plugged into a receiver which decodes the optical signal back into digital pulses.

Multimode vs Singlemode Fiber

A “mode” in Fiber Optic cable refers to the path in which light travels. Multimode cables
have a larger core diameter than that of singlemode cables. This larger core diameter
allows multiple pathways and several wavelengths of light to be transmitted. Singlemode
cables have a smaller core diameter and only allow a single wavelength and pathway
for light to travel. Multimode fiber is commonly used in patch cable applications such
as fiber to the desktop or patch panel to equipment. Multimode fiber is available in
two sizes, 50 micron and 62.5 micron. Singlemode fiber is typically used in network
connections over long lengths.

Advantages & Disadvantages of Fiber Optic cable

There are many advantages and disadvantages in using fiber optic cable instead of
copper cable. One advantage is that fiber cables support longer cable runs than copper.
In addition, data is transmitted at greater speeds and higher bandwidths than over copper
cables.
The major disadvantages of fiber optic cables are cost and durability. Fiber cables are
more expensive than copper cables and much more delicate.
