Sample questions
01What is the maximum recommended pulling tension for standard fibre optic cables?
- A5000N (varies by cable type)
- B50N (varies by cable type)
- C600N (varies by cable type)
- D200N (varies by cable type)
Why: Maximum pulling tension varies by cable type—typically 600N for standard indoor cables, up to 2700N for outdoor cables with appropriate strength members. Always check manufacturer specifications.
02Why should fibre optic cables not be routed in the same pathway as high-voltage electrical cables?
- AOptical fibres are conductors at high voltage
- BThe fibre will absorb electrical energy
- CTo comply with separation requirements and prevent physical damage
- DElectromagnetic interference affects optical signals
Why: While fibre is immune to EMI, codes require separation for safety (avoiding contact with high voltage), maintenance access, and preventing physical damage during electrical work.
03What is the purpose of using cable lubricant during fibre cable installation?
- ATo seal the cable end against moisture ingress
- BTo reduce friction and pulling tension during installation
- CTo bond the cable jacket to the conduit wall
- DTo block water from migrating along the cable core
Why: Cable lubricant reduces friction between the cable jacket and conduit, significantly reducing required pulling tension and preventing cable damage during long pulls.
Common questions
Is the Installation mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
