SWA Mulit Loose Tube Fibre Cable is suitable for direct burial installations making it the perfect solution for the most demanding and harsh environments.

The SWA fibre cable has excellent tensile strength and the layer of 0.9mm steel wire provides safe rodent protection.

This tough rugged cable is ideal for all external environments including direct burial, tunnels and heavy duty ducts.Water Resistant, Rodent Resistant, Flame Retardant

Features:

●Excellent mechanical and temperature performance guaranteed by the accurate excess fiber length

●Critical protection to fibers,

●Excellent crush resistance and flexibility

●The following measures are taken to ensure the water blocking performance of the cable:

- Single steel wire used as the central strength member

- Special water-blocking filling compound in the loose tube.

PSP moisture barrier

- water-blocking yarn and water swellable material tape double water proof
