Choosing a Fiber Optic Cable Type for Your Installation
The four general types of Fiber Optic Cables shown below will cover 99% of the installations that you are likely to encounter. Please read on and let us know if you have any special requirements for your project not covered by the following cable types:
INDOOR PLENUM (Tight Buffer)
Best Suited for: virtually all (dry) indoor locations. This cable can be run in Plenum and Riser spaces. It is normally considered to be the best choice for indoor use.
Best Suited for: Outdoor installation either exposed or underground in conduit. It is not recommended for locations where extreme changes in temperature are likely to occur or for freezing and thawing conditions. Can be run indoors without limit so long as it does not enter a plenum air space. The jacket is UV rated for prolonged exposure to the sun. This cable is not recommended to be direct buried due to its lack of armor for rodent chew-through protection. This cable is made with Water Block technology.

OUTDOOR CABLES (Loose Tube, Armored, Gel Filled)
This cable is made utilizing loose tube gel filled construction with an overall armor under the outside jacket. Together, the armor and gel filled construction are designed to minimize the risk of damage due to rodent chew through, freezing and thawing and light crushing forces. The jacket is UV rated for prolonged exposure to the sun.
Best Suited for: Direct Bury and locations with extreme changes in temperature. Building codes limit this cable to a maximum of 50 feet run indoors. Also, this cable is not recommended for conduit pulls where there are many bends.

Best Suited for: Interlocking Armor is commonly used for mission critical, heavy industrial and/or high security applications where it is not practical to pre-install a conduit. These cables are available in versions that can be used in both Indoor Plenum spaces and direct bury and other outdoor locations. Interlocking Armor cables can save a lot of time and money by eliminating the installation and use of conduit.
Best Suited for: Outdoor Aerial cables are typically used to span distances from utility pole to utility pole and from utility pole to building. The messenger is typically made of high tensile strength steel and is used as the strength member to carry the weight.
