Fibre network build
Build the fibre network: street cabinets, distribution points on poles, and the fibre that links them back to the exchange.
Overview
Light starts at the OLT in the exchange, travels out through cabinets, along aerial or underground fibre to distribution points (CBTs) on poles, then down drop cables to each home's ONT. A cabinet or DP with no fibre back to a lit source is useless: every ONT behind it stays dark. Fibre installation jobs are checked by the cable you actually lay; cabinet and DP jobs by the kit you fit near the job site.
Jobs this covers
fibre_install, fibre_cabinet, fibre_dp — certificate: Fibre splicing & testing (required)
The equipment — what everything does
Street cabinet (PCP / FTTC)
Houses splitters and joints where feeder fibre fans out to an area.
In game: /towers → OPS Openline → street cabinets.
Distribution point (CBT)
Pole-top box that serves up to 4–8 homes.
In game: Fitted from the pole menu (G while climbing).
Fibre cable (aerial / underground)
Carries the light between exchange, cabinets and DPs.
In game: Fibre cabling tools: run between kit, clamp to poles, or pull through ducts.
Splice enclosure / joint
Protects splices where two cables meet.
In game: Placed on poles or in chambers from /towers.
Tools & PPE
Fibre fusion splicer
Melts two cleaned and cleaved fibres together into one low-loss joint.
Optical light meter / OTDR
Measures how much light arrives down a fibre, and where along it a break or bad splice is.
Ladder
Reaches walls, ceilings and pole steps. Place it at a 1-in-4 angle on firm ground.
Spade & draw rope
Opens chamber lids and pulls cables through underground ducts.
Cones & barriers
Keeps people and traffic away from open chambers, cabinets and ladders on the pavement.
Hi-vis vest & hard hat PPE
Makes you visible to traffic and protects your head from falling objects and low beams.
Fall-arrest harness PPE
Clipped to a pole or anchor point, it stops a fall when you work above 2 m.
Safety glasses PPE
Protect your eyes from fibre shards, drilling dust and laser light.
Insulated gloves PPE
Rated gloves for work near live electrical parts and for sharp metal edges.
Standalone servers: tools are in your van (OPS Work → My van & tools). Items servers: collect them — and the job’s parts — at an OPS depot.
Step by step
Put out cones and barriers around the pole, cabinet or chamber.
Place the street cabinet from /towers, or climb and fit the CBT from the pole menu.
Run fibre from the lit network to the new kit: clamp it to poles, or open a chamber and pull it through the duct with the draw rope.
Splice the fibres and seal the joint in an enclosure.
Use the light meter at the new kit. No light means a break or bad splice — find it with the OTDR.
Press Check on the job, then close chambers and remove cones.
Health & safety
Working at height
Risk: A fall from a ladder or pole can cause serious injury.
Control: Use a ladder at a 1-in-4 angle on firm ground with three points of contact. Above 2 m on a pole, clip on your harness.
Working in the street
Risk: Traffic and pedestrians around open chambers, cabinets and poles.
Control: Wear hi-vis and set out cones and barriers before you start. Never leave a chamber open and unattended.
Underground chambers
Risk: Lids are heavy, and gas can build up in chambers.
Control: Lift lids with the proper key using your legs, let chambers vent, and never climb in alone.
Laser light
Risk: Invisible laser light damages eyes.
Control: Never look into fibre ends.
In game you confirm these in a risk assessment before starting. Skipping them on risky work can cause a fall or a shock — and it’s logged as a safety incident.
When it’s not done correctly
Fibre run not connected back to a lit source
The new cabinet/DP gets no light, and every home behind it stays dark.
Too little cable laid for a fibre install
The 'cable laid' check counts metres since you accepted the job. Too short and it fails.
Chamber left open
A hazard to the public. With incidents on, someone can get hurt and it's logged against you.
Wrong kit model fitted
The fixtures check only counts the models the job lists, so the job stays open.
