Training covers:
Fibre cleaving
Splice preparation
Fusion splicer setup
Heat shrink protection
Splice trays
Best practice techniques
You'll also learn how poor preparation affects splice quality and how experienced engineers troubleshoot common splicing problems before they impact network performance.
Rather than simply following a procedure, delegates develop an understanding of what separates a high-quality splice from one that may create long-term reliability issues.
Fibre Optic Connector Installation
While fusion splicing is commonly used within the network itself, many fibre installations also require connectors to terminate cables and allow equipment to be connected or disconnected when necessary.
Understanding how to prepare, install and inspect connectors is an important skill for any fibre optic engineer, as poorly terminated connectors are one of the most common causes of network performance issues.
During the course, you'll gain practical experience working with fibre connectors and learn the techniques required to achieve clean, reliable terminations.
You'll cover topics such as:
Connector types and applications
Fibre preparation techniques

Common connector faults
Attention to detail is critical throughout this process. Even microscopic contamination can significantly increase signal loss, which is why professional engineers always follow strict cleaning and inspection procedures before commissioning a fibre link.
Fibre Optic Testing and Certification
Installing fibre is only one part of the job. Before a network can be handed over to a customer, every fibre must be tested to confirm it meets the required performance standards.
This is where fibre optic testing becomes essential.
Our course introduces delegates to the testing equipment and procedures widely used throughout the telecoms industry. Rather than simply pressing buttons on a tester, you'll learn how to interpret results and understand what they reveal about the quality of an installation.
Practical training includes using professional testing equipment to assess attenuation, continuity and overall network performance.
You'll also develop an understanding of:
Optical Loss Test Sets (OLTS)
Visual Fault Locators (VFL)
Light sources and power meters
End-to-end loss testing
Test result interpretation
Recording and documenting results
Employers increasingly expect engineers to produce accurate test records as part of every installation.
Learning how to carry out testing correctly helps ensure networks perform reliably while reducing the likelihood of costly return visits.
Understanding OTDR Testing
One of the most valuable diagnostic tools available to fibre engineers is the Optical Time Domain Reflectometer (OTDR).
Although OTDR testing is a specialist discipline in its own right, this course introduces delegates to the principles behind the technology and explains how OTDR traces are used to identify faults within fibre networks.
You'll gain an understanding of:
How an OTDR works
Reading OTDR traces
Identifying splice losses
Detecting connector reflections
Locating fibre breaks
Understanding dead zones
Having a working knowledge of OTDR testing allows engineers to communicate more effectively with testing specialists and better understand how installation quality influences final network performance.
