SC1 (< 1 cm)
Refer to Moderate damage (1 to 45 cm) on page 158, to repair minor damage to SC1 sensor
cable.
SC2 (< 1 cm)
To repair minor damage, make a cable splice consisting of two male TNC connectors and one
female coupler at the damaged section. Use heatshrink to seal the splice.
1. Cut the cable at the centre of the damaged section.
2. Using a damp cloth and mild detergent, clean and dry the two cable sections thoroughly in the
area of the cable damage.
3. Examine the cut ends of the cable for any signs of corrosion on the center conductor.
If any corrosion is present, strip back the cable until you reach uncorroded center conductor.
4. Classify the cable damage based on the length of removed cable. If removing corroded cable
resulted in an increase in the level of cable damage (to moderate or severe) refer to the
appropriate section for details. See Cable damage assessment table
on page 156.
5. Install TNC connectors on the two cut cable ends. See Installing connectors on OC2 sensor
cable on page 121.
6. Test the connectors to ensure proper installation. See Cable tests
on page 146.
7. Slide on the 30 cm section of heatshrink tubing, and join the male connectors with a female to
female coupler.
8. Position the heatshrink tubing over the connectors and apply heat to seal the heatshrink (see
Sealing the heatshrink over decouplers/splices
on page 133).
9. Note the location and a brief description of the cable damage on the site plan.
Moderate damage (1 to 45 cm)
To repair moderate damage, cut out the damaged section of cable and splice in new cable. The
