What is a cable marker?

A durable ID label clipped onto a cable so it can be identified on site: cable ID, type and route.

Why: On a busy route the only way to know which cable is which, safely, is a clear label at the points people work.

Where: At building and cabinet entries, either side of joints and sheath gaps, and at screening conductor earth points (per the legacy FTN labelling spec).

Where the rules are

• SP FTN (D&D) 016 cl 6.2.1where markers go on fibre and copper cables (legacy FTN spec)
• SP FTN (D&D) 016 cl 6.2.2markers at joint closures
• SP FTN (D&D) 016 cl 6.2.6markers at screening conductor earths
