project 1

Duct Integrity Test

Label Fibre Optics
Type Duct Integrity Test (DIT)
Category Telecommunications

After backfilling ducts shall be tested for integrity (air tightness and kink-free shape). Air tightness test is done by pressurizing 2 km duct stretches at a time. One end of duct will be closed and compressed air at 5-6kg/cm2 is sent from the other end. At about 5kg/cm2 pressure the inlet of compressed air will be closed. Fall in pressure should not be more than 50% in 1(one) hour. To check that duct has not collapsed or kinked a wooden cylindrical piece (shuttle) is blown into the duct with far end fitted with Flexible wire grip/stocking. The wooden shuttle should pass through duct at far end without any obstruction and within approx. 10 minutes or less.

project 6

Fibre Floating-Micro/Bare

Label Fibre Optics
Type Fibre Floating (Hauling/Blowing)
Category Telecommunications

Cable floating is the process of blowing a cable through a duct while simultaneously pushing the cable into the duct.
Compressed air is injected at the duct inlet and flows through the duct and along the cable at high speed. The high speed air propels the cable due to drag forces and pressure drop.

Advantages of blowing compared to pulling:

- Longer installation distances can be reached
- Installation distance less dependent on bends and undulations in duct
- Forces exerted on the cable are lower
- Easier use blowing in tandem operation
- The step of installing a winch rope is avoided
- Equipment is needed only at one end of the duct route

project 7

Fibre Splicing

Label Fibre Optics
Type Fibre Splicing
Category Telecommunications

Current fusion splicers are either core or cladding alignment. Using one of these methods the two cleaved fibers are automatically aligned by the fusion splicer in the x,y,z plane, then are fused together. Prior to the removal of the spliced fiber from the fusion splicer, a proof-test is performed to ensure that the splice is strong enough to survive handling, packaging and extended use. The bare fiber area is protected either by or with a splice protector. A splice protector is a heat shrinkable tube with a strength membrane and less loss.

A simplified optical splicing procedure includes:

  1. Characteristics of placement of the splicing process.
  2. Checking fiber optic splice closure content and supplementary kits.
  3. Cable installation in oval outlet.
  4. Cable preparation.
  5. Organization of the fibers inside the tray.
  6. Installing and testing it.
