Understanding Fiber Optics

Lemberg specializes in the installation of fiber optic cabling used for data, voice and video transmission. But, what exactly IS a fiber optic cable and what do you need to know as a consumer?

Fiber optic cabling is a system of very thin glass or plastic strands, about the thickness of a human hair, which are bundled together under a casing and used to transmit information. It is the behind-the-scenes conduit that supports daily activities such as point of sales transactions, surveillance, medical scopes, computer networking, image transfers and communications.

Fiber optics depend upon light pulses to transmit from one end of the cable to another. The fiber itself is made from layers of transparent glass, a mirrored casing and a coating that seals and protects the cable from environmental damage. As it passes through the cable, light bounces within the casing until it reaches the other end. The rate of this transmission is known as “bandwidth.”

Benefits of Fiber Optics

Most communication networks utilize fiber optics, which provide faster internet and telephone connections than traditional copper wiring. It is preferred for its reliability, expandability, capacity and capability for transmitting over longer distances without signal degradation.

Challenges to Using Fiber Optic Technology

Fiber optic technology can be more expensive per foot, but since fiber optics can carry more signals a farther distance, the expense is offset by the decrease in number of repeaters needed. Fiber optic technology is sensitive, so environmental factors such as moisture, tension, heat, chemicals, flexibility, and nature are all things to consider during cable installation. Fiber optics are not as easily connected as traditional wiring, so professional installation is required.

Installation Facts

The use of the fiber optics determine the cable -- larger core, multi-mode fiber optics are used for shorter distances, generally within a building; and smaller core, single-mode fiber with a larger cladding is used for longer distances, typically outdoors between buildings.

Qualified technicians will evaluate requirements and suggest the correct fiber optics for a given situation and consider future growth when quoting an installation.
