Cables without markings ought to never be installed indoors as they won't cross building inspections! Outdoor cables usually are not hearth-rated and may only be used as much as 50 ft indoors.

Choosing a cable requires consideration of all the environmental components involved throughout set up and in the course of the cable's lifetime.

PVDF is used for plenum cables as a result of it has better fire-retardant properties than PE and produces little smoke. Corning’s micro cabling solution solves the demand for today’s unlimited bandwidth capacity and addresses escalating community duct congestion.

Plenum is an air-handling, air flowing and air distribution system space such as that found above drop ceiling tiles or heating and air flow ducts. Plenum rated cables must meet UL-910 specification and their outer jacket are manufactured from materials that retard the unfold of flame, produce little smoke and shield electronic gear from harm in fires. Plenum cables can be run through plenum spaces without special conduits. Plenum rated cables are more expensive, due to the jacket materials, but the added security and extra conduit value savings pays that back. Fiber optic cable can be found in a wide variety of physical constructions.

Look at the pictures below to see how every kind of cable incorporates these parts. Our in depth line of indoor and out of doors cable products are third-party tested by Electrical Testing Laboratories or Underwriters Laboratories , and approved to be used by the National Electric Code . Armored cable can be used for rodent protection in direct burial if required.

Riser is a pathway similar to floor opening, shaft or duct that runs vertically via flooring. Riser rated cables may be run through building vertical shafts or from one floor to a different floor.

Per NEC code out of doors cables and unmarked cables could be put in indoors but they need to be utterly installed in metallic conduit or electrical metallic tubing.

Fiber cables could be anything from simple simplex or duplex cables used for jumpers to 144-fiber cable for intercity transmission. LSZH plastics are used for a particular type of cable known as LSZH cables.
