(Typical 20 m) Step 2 On the subscriber’s floor pull back the

selected fibre module

Step 1 On a higher floor cut

The Stripping Tool has been designed to safely cut the windows on the Riser Cable.

If used properly, it cannot damage the fibre units.

2nd window cut: “extraction window”

1st window cut: “pick window”

The basic principle

5 Easy Steps

LAY the RetractaCable from Distribution Point along the Homes.

OPEN the RetractaCable in front of the homes to connect.

CUT the desired fibre module in the first next (from DP) opened cable spot.

PULL the cut fibre module out (retract), in case the length is > 50 meter a tool can be used for retracting, storage and pushing or blowing.

PUSH and/or BLOW the retracted fibre module through a drop duct up to the home.

The basic principle

Two ways to extract fibre modules

•  Cut the fibre module one home further and splice the fibres in the home.

•  Cut the fibre module 1.5m from the home and splice the fibres at the tap-off point

 Designed for Indoor and OSP

 Reduction of 15 to 30% on installation time

 Extremely Compact (i.e. 720fo cable with 16mm O.D.)

 No cable loop, very small closures, prefab. manholes

  Ideal for installation in existing / new duct infrastructures or in soft soil.

 The simplicity of the concept reduces the need for skilled labour

  Extremely efficient in both brownfield & greenfield sites
