Generic Requirements for Premises Fiber Optic Cable
GR-409-CORE Generic Requirements for Premises Fiber Optic Cable is a document specifying testing requirements for singlemode and multimode optical fibers, buffered fibers, optical fiber ribbons, and optical fiber cables. Premise fiber optic cables are meant for indoor use such as home or office, but limited outdoor use is also acceptable.
There is a wide variety of fiber types that can be designed with a coating material and/or buffered to a diameter of 250 µm or 900 µm. There are generally two classifications of indoor cable
• Backbone cables – higher degree of robustness
• Interconnect cables – relatively light-duty use
Also there are flammability ratings based on NEC
• Plenum cable – NEC Type Optical Fiber Nonconductive Plenum (OFNP) cables are fire rated to allow direct placement in air handling plenums (ceiling or under floor). Cables with this fire rating may also be used in riser and general purpose applications.
• Riser cable – NEC Type Optical Fiber Nonconductive Riser (OFNR) cables are rated to allow use between floors or in a riser shaft of a building. Cables with this flame rating may also be used in general purpose applications.
• General purpose cable – NEC Type Optical Fiber Nonconductive (OFN) or Optical Fiber Nonconductive General-Purpose (OFNG) cables are rated for use on one building level or for connecting two immediately adjacent dwelling levels (one- or two-family dwellings, only).
Experior Labs maintains accreditation to conduct testing to GR-409 Generic Requirements for Premises Fiber Optic Cable. Our project managers have the technical fiber optic expertise to properly handle the testing of GR-409 products.
