To Understand Fiber Optic Cable Jacket & Fire Rating

Fiber Optic Cable Jacket Material

Fiber cable jacket is made of various types of materials. It’s important to consider the jacket type when selecting the compatibility with the application’s connectors and environment.

Fiber Optic Cable Fire Rating

Typically, there are eight levels of fire resistance for both non-conductive and conductive cables specified by NEC (National Electrical Code). All indoor fiber optic cables must be marked and installed properly for its intended use: plenums, risers and general purpose areas.

Note:

(1) A Plenum area is a building space used for air flow or air distribution system (drop ceiling and raised floors).
(2) A Riser area is a floor opening, shaft or duct that runs vertically through one or more floors.
(3) A general purpose area is all other area that is not plenum or riser and on the same floor.

OFNP vs. OFNR

OFNP and OFNR are two types of fiber optic cables that are used in buildings. OFNP cables have fire-resistance and low smoke production characteristics. This is the highest fire rating fiber cable and no other cable types can be used as substitutes. So these cables are mostly installed in plenum areas. Whereas, the fiber-resistance and low smoke of OFNR cables are not good as OFNP. OFNP plenum cables can be used as substitutes for OFNR cables.

FTTH Cabling System

A Future-Proof Solution for Access Network

Outside Plant Components for FTTH Network
In order to get more clear about FTTH cabling, it is important to know the components in the FTTH network.
OLT: Optical line terminal in a PON system, located in the central office (CO) or hut, is the interface to the subscriber and provides the subscribed services.
ONU: Optical network unit, used to convert optical signals via fiber to electrical signals.
ONT: Optical network terminal, electronics generally located on subscriber premises, basically the same device as ONU.
Splitter: Passive device that splits the light source in sperate paths in a PON system.
