Fibre Bundle

We specialise in the termination of optical fibres, connectors and devices across diverse sectors, medical, aerospace, sensor, telecommunications, defence and more.

To achieve high throughput with flexible glass or plastical optical fibres, multiple fibres are often arranged in a bundle. This is also desirable when light sources are not point-like and thus cannot be focused to small diameters. However light losses are inevitable for two reasons:
1. For a given fibre, the maximum usable area is defined by the core and cladding diameters. These diameters determine the fibre packing factor (FPF).
2. When fibres are arranged in a bundle, not all of the bundle cross-sectional area is filled with fibres, even when tightly packed arrangements are used. The particular packing arrangement defines the bundle packing fraction (BPF).
