What is Fibre Splicing?

Fibre optic splicing is the process of permanently joining two optical fibres together. It is a crucial technique in fibre optic communication networks, as it allows for the creation of longer fibre optic cable runs and the repair of damaged or broken fibre cables.

The splicing process involves carefully aligning the cores of the two fibres and fusing them together using heat or an electric arc. The goal is to create a seamless connection that minimizes signal loss and maintains the integrity of the optical signal transmission.

There are two main methods of fibre optic splicing:

1. Fusion splicing:
   • In this method, the ends of the two fibres are precisely aligned and then heated using an electric arc or a high-temperature filament.
   • The heat melts the glass fibres, and when the heat source is removed, the two fibre ends fuse together, creating a continuous and permanent connection.
   • Fusion splicing is the preferred method for most fiber optic installations due to its low signal loss and long-term reliability.
2. Mechanical splicing:
   • In mechanical splicing, the fibre ends are held together using a precision-engineered mechanical device or connector.
   • The fibres are aligned and secured within the connector, which holds them in place and guides the optical signal from one fibre to the other.
   • Mechanical splices are generally easier and faster to perform than fusion splices, but they may introduce slightly higher signal loss and are less durable over time.

Fibre optic splicing is an essential skill in the telecommunications industry, as it allows for the construction and maintenance of long-distance fibre optic networks. It is also used in various other applications, such as fibre optic sensing systems, fibre lasers, and fibre optic gyroscopes.

Proper splicing techniques and equipment are crucial to ensure low signal loss, long-term reliability, and optimal performance of fibre optic communication systems. Splicing requires specialized training and equipment, and it is typically performed by skilled technicians or splicers.
