Programme overview
Introduction:
Fibre optic networks carry telecom, enterprise and utility traffic, yet many outages trace back to poor splices, dirty connectors, tight bends, missing records or an OTDR trace nobody could read. This Core Concept course trains engineers and technicians to design fibre links against a loss budget, install cable in duct, aerial and indoor routes, make fusion and mechanical splices, test with a power meter and OTDR, locate faults and restore service safely. Participants build a Fibre Link Design, Test and Restoration Pack for a real route.
Course Objectives:
- Select single-mode or multimode fibre, cable construction and connector types for a given link distance, bandwidth and environment
- Calculate an end-to-end optical link loss budget and design point-to-point, backbone and FTTx/PON routes with splitter plans
- Install fibre cable in duct, aerial and indoor pathways within bend radius and pulling tension limits
- Perform fusion and mechanical splices and terminations that meet splice loss and reflectance targets
- Test fibre links with an optical power meter, light source and OTDR, then interpret traces to locate faults and high-loss events
- Produce a Fibre Link Design, Test and Restoration Pack with as-built records, acceptance results and an emergency restoration procedure
Target Audience:
- Telecom engineers and technicians who plan, build and maintain outside plant and access fibre networks
- Network engineers responsible for campus, data centre and backbone fibre links
- Utility and OT communications engineers maintaining fibre along power lines, pipelines and substations
- Field technicians who splice, terminate and test fibre cable during installation and repair
- Network operations and maintenance staff responsible for fault response, fibre records and restoration

Skills You Will Gain:
- Fibre Type and Cable Selection
- Optical Loss Budget Calculation
- PON Splitter Planning
- Fibre Cable Installation Practice
- Fusion Splicing
- OTDR Trace Analysis
- Fibre Fault Location
- Fibre Plant Documentation
Why Attend This Course:
- Return with a Fibre Link Design, Test and Restoration Pack built for a route in your own network
- Cut repeat faults by applying splice, connector cleaning and bend radius practice checked in the lab
- Read OTDR traces well enough to accept contractor work or dispute it with evidence
- Compare fibre build and repair practice with engineers from telecom operators, utilities, oil and gas and enterprise networks
Conclusion:
Fibre networks stay reliable when design, installation, splicing, testing and records follow one consistent method. The course moves from optical fibre principles and components, through fibre types, cables, connectors and point-to-point, backbone and PON architectures, to loss budgets, installation and splicing, then power meter and OTDR testing and fault location. The final day applies these methods in hands-on labs and produces a Fibre Link Design, Test and Restoration Pack ready for field use.
