Southampton University spin-off Lumenisity® Limited, has released a new generation of hollowcore fibre, DNANF®. The company says the technology has the lowest attenuation of any hollowcore fibre reported to date, and in doing so surpasses the attenuation of conventional germanium-doped single-mode fibre (SMF) in the O and C bands. DNANF is Lumenisity’s latest evolution of its Nested Anti-resonant Nodeless Fibre (NANF®) hollowcore technology, jointly developed with the University of Southampton in the UK.

With attenuations of <0.22 dB per km at 1310nm and <0.18 dB per km at 1550nm, this new fibre technology has achieved the lowest loss ever recorded for any optical fibre in the O band and comparable or better than conventional single mode fibre in the C band. The results are thought to be the first of this kind reported.

NANF offers ultra-low latency, lower dispersion, lower nonlinearity and higher power handling. As DNANF has lower optical loss, this technology offers the promise of even greater optical transmission capacity, longer reach and broader spectral bandwidth. It unlocks the potential for ultra-low latency cables for use in long haul and future submarine networking applications.

Tony Pearson, VP Sales & Marketing at Lumenisity said, “Our latest innovation continues the realisation and productisation of fibre and cabled solutions that offer new networking tools previously unavailable with conventional silica based single-mode products. This achievement underpins Lumenisity’s goal to deliver the most advanced hollowcore fibre optic cable solutions for our customers and partners.”

David Parker, Chairman at Lumenisity said, “We are very excited about this ground-breaking fibre development. We will now look to start shipping DNANF cabled solutions to customers in the second half of this year from our new, state-of-the-art hollowcore fibre manufacturing facility located in Romsey, UK; the first of its kind in the world.”
