Introduction:
Fibre optic cable splicing is a critical process in fibre optic network installations, allowing technicians to create seamless connections between fibre optic cables. Understanding the techniques and equipment involved in fibre optic cable splicing is essential for ensuring reliable and efficient connectivity. In this comprehensive guide, we'll explore the techniques, equipment, and best practices for fibre optic cable splicing to help you master this essential skill in fibre optic installations.
Techniques for Fibre Optic Cable Splicing:
- Fusion Splicing:
- Description: Fusion splicing is a method of joining two fibre optic cables together by melting and fusing the ends of the fibres using heat.
- Process: The fibres are precisely aligned using a fusion splicing machine, and a controlled arc or laser heat source is applied to melt the fibres together, creating a seamless connection.
- Benefits: Fusion splicing provides low insertion loss, high mechanical strength, and low reflectance, making it ideal for long-haul and high-speed fibre optic networks.
- Mechanical Splicing:
- Description: Mechanical splicing is a method of joining two fibre optic cables together using a pre-aligned splice sleeve or connector.
- Process: The fibres are cleaved and inserted into a splice sleeve or connector, where they are held in place by mechanical means such as screws or clamps.
- Benefits: Mechanical splicing is quick, simple, and cost-effective, making it suitable for temporary or emergency splices and repairs.
Equipment for Fibre Optic Cable Splicing:
- Fusion Splicing Machine:
- Description: A fusion splicing machine is a specialised device used to align and fuse fibre optic cables together during fusion splicing.
- Features: Fusion splicing machines typically include features such as automatic fibre alignment, programmable settings, and splice quality monitoring.
- Brands: Popular fusion splicing machine brands include Fujikura, Sumitomo, and AFL.
- Cleaver:
- Description: A cleaver is a precision cutting tool used to create a flat and perpendicular end face on a fibre optic cable before splicing.
- Types: There are various types of cleavers available, including single-fibre cleavers, ribbon fibre cleavers, and automatic cleavers.
- Brands: Common cleaver brands include Fujikura, Sumitomo, and Fitel.
- Splice Sleeves and Connectors:
- Description: Splice sleeves and connectors are used to protect and align the spliced fibres during fusion or mechanical splicing.
- Types: There are various types of splice sleeves and connectors available, including heat-shrink sleeves, mechanical splice connectors, and fusion splice protectors.
- Brands: Splice sleeves and connector brands include 3M, Corning, and AFL.
