Hollow Core Fibre (HCF)
Hollow Core Fibre (HCF) is a type of optical fibre in which light primarily travels through a hollow core rather than a solid glass or silica core, as is the case with conventional optical fibres. This hollow core reduces the latency of transmissions and allows for even greater capacities to be supported.
NPS has been working with hollow core fibre for over 6 years, and we have established ourselves as an expert in what we believe is a game-changing technology, but a critical one if we are to continue to meet the future demands of data transfer.
We have comprehensive knowledge and first-hand experience deploying hollow core fibre networks and we’d be happy to share our expertise with you, and explore how it can be deployed within your network infrastructure.
If you’d like to have an initial chat or wish to discuss a specific project, contact Joe Dickenson at Joe@npsltd.net, who will be happy to assist you and talk you through the many benefits of hollow core.
Advantages of Hollow Core Fibre(HCF):
Lower Losses at Certain Wavelengths
HCFs offer reduced transmission losses, particularly in the mid-infrared range, where traditional optical fibres suffer from high attenuation. This makes them ideal for specialised applications, such as sensing or medical lasers.
Reduced Latency
Light in HCFs travels faster because air has a lower refractive index than glass. This reduction in latency is beneficial in sectors that require high-speed data transmission – such as telecommunications, high frequency trading, AI and high-performance computing.
Lower Nonlinearities
Since most of the light travels through air or gas rather than solid glass, HCFs exhibit much lower nonlinear effects (such as the Kerr effect or Raman scattering), which are common in conventional fibres. This allows for higher signal quality and the potential for high-power transmission over long distances.
High Power Handling
With minimal light-matter interaction, HCFs can handle higher optical powers without damage or distortion. This is useful in applications like high-power laser delivery systems.
Better Polarization Control
HCFs can offer improved polarization-maintaining capabilities that are useful in applications requiring precise control of light polarisation, like quantum communication.
Resistance to Radiation Damage
HCFs are less sensitive to radiation, making them ideal for use in harsh environments such as space, nuclear facilities, or military applications.
