Fibre optic and cabling tech firm Lumensity has closed a £7.5m funding round from a consortium of investors.

The Reading firm develops and manufactures advanced cable solutions to address the need for high speed transactions and bandwidth increases in high capacity communications systems.

The firm’s hollowcore fibres allow light to propagate in an air containing core formed by microscopic capillaries, an advancement in fibre optic cable technology.

This investment comprises of a £5m investment from BGF, the UK and Ireland’s most active investor, and £2.5m from Parkwalk, the most active investor into UK university spinouts, alongside significant further funding from the company’s existing industrial strategic investors.

The investment will be used to further commercialise the world leading research beyond current products and to build a new manufacturing and testing facility.

The firm has worked in collaboration with the University of Southampton, to create cables suitable for deployment in meaningful lengths for the network.

Datacentres, a key market for the business, will be able to extend their network over a broader area with increased speed and capacity, driving network efficiency and enabling access to affordable real estate and utilities, the firm said.
