On 16th December 2022, Microsoft announced the acquisition of Lumenisity Limited, a UK-based company specializing in next-generation hollow core fiber (HCF) solutions. Lumenisity's HCF technology offers fast, reliable, and secure networking solutions for various industries, including healthcare, financial services, manufacturing, retail, and government. The acquisition aims to enhance Microsoft's Azure-branded cloud computing services by replacing the standard glass core in fiber cables with an air-filled chamber, thereby improving data transmission speeds and security. Lumenisity's technology has attracted interest in expanding data center geographic reach beyond mobile backhaul.
