As the low-voltage industry reaches for higher bandwidth and longer distances for communications, fiber optic cable becomes the primary medium to achieve great distance and big bandwidth.

Fiber optic cables provide three critical advantages over UTP/coax.  Standard multi-mode fiber has the potential for over 40 times the bandwidth of Cat5e UTP, so there is plenty of headroom for carrying high-bandwidth connectivity from devices such as multi-megapixel IP cameras.  The second advantage of fiber optics is the potential for great distances.  Where the EIA/TIA standards state that Cat5e/6 UTP cables should be a maximum length of 100 meters, fiber optic links can easily transmit and receive signals over distances from 3 feet to 50 miles, based on the type of fiber used and the power of the transceiving equipment.  The third advantage of using fiber optics is that it is completely immune to RF and EMI interference.  The signals going through a fiber link are blinking lights and are unaffected by any type of electrical or RF activities. 

Choosing fiber optic cables requires some specific information on the part of the system designer to ensure that the correct cable is installed.  The two broad categories of fiber optic strand types are multi-mode and single-mode.  In common use, multi-mode fiber is connected within a single building or a campus of buildings and has a usable maximum distance of 1.2 miles from end to end.  Single-mode fiber is primarily used for outdoor multiple mile connections such as those provided by the data, telecom, and “fiber to the home,” companies.

When choosing your fiber make sure that you are specifying cables that meet the appropriate NEC codes for general use, plenum, and riser based on the anticipated installation.

It is also very important to measure the distance of the planned fiber link(s) very carefully.  System designers should plan to have at least 30 feet of excess fiber cable at each end of an installation.  Having this sufficient “slack” fiber will make terminations easier as the cable end can be brought to a usable working surface. This also means the inevitability of breaking small lengths of fibers during the stripping and termination process will be of little concern since there is plenty of spare fiber on each end.

ADI now has the capability to cut ship specific lengths of fiber optic cable.  Just make your measurements, select the fiber type of choice, and contact your ADI representative.
