FTTH Round Cable Double Sheath Outdoor Indoor Optical Fiber Network 4.6mm GJYFJH
When entering a building, the outer sheath of the cable is simply
removed to expose the inner flame retardant Jacket. The operation
is swift and enables easy installation from an outdoor environment
to an indoor environment without the need of two different cables
and a cable joint.
The drop cable is primarily intended for direct installation, i.e.
installation with staples or clips or routing inside cable raceways
and buildings. This installation technique puts extra tough
requirements on the cables in terms of bend performance, crush
resistance and other mechanical parameters.
The LSZH Dual Jacket Cable is a fibre optic drop cable for
indoor/outdoor FTTx applications. The unique dual jacket design
enables the cable to be installed outdoors as well as short
sections indoors. The cable has dual Low Smoke flame retardant
sheaths, the outer is a UV-resistant black variant.
The drop cable has extremely good bend performance due to the G657
fibre and the inbuilt bend restriction of the cable design. The
cable will by itself control the minimum bend radius and permit
kinking.
