Fiber Optic Cables
Tight Buffer
Application
This cable is used for interconnection of the distribution boxes and end devices. The cable is very suitable for
various indoor and outdoor applications, including routing between buildings within ducts and inside building up
to riser shafts.
Description
The Distribution Cable consists of color-coded PVC tight buffered fi bers. The fi bers are reinforced with aramid
yarn for superior strength and contains no metallic elements. The fi bers are jacketed with Flame Retardant PVC
or LSZH compound.
