FTTH INDOOR/OUTDOOR DROP CABLE

Indoor cable series:

These indoor fiber optic cables are used exclusively within buildings and must have a flame-retardant jacket to fit this purpose. 

They Flame resistant cable may be deployed in-duct (conduit) or cable tray. When routing a cable within a building, you will also need to factor in fire prevention requirements. 

These requirements differ per country and region of the world.

Outdoor cable series:

Fiber optic cables for outdoor applications are engineered to withstand the more demanding conditions seen outside, from environmental extremes to mechanical forces. These are the outdoor fiber optic cables you see strung along telephone poles (aerial), installed inside an underground duct, or even buried directly below ground. Outdoor  cables therefore feature rugged constructions to resist ultra-violet light and temperature fluctuations and may include features to withstand the requirements of being installed outdoors.
