Lightera has announced an expansion of its manufacturing footprint for multi-core optical fiber, targeting production facilities in Brondby, Denmark and Norcross, Georgia. The capital expenditure initiative is designed to prepare for a shift toward high-capacity multi-core networking technologies.
Why it matters
As data centers face increasing bandwidth constraints, the industry is transitioning to multi-core optical fiber to increase throughput per cable. This infrastructure expansion is intended to ensure supply chain readiness for the anticipated shift in networking hardware.
Lightera aims to scale its manufacturing capacity by nearly 3x by 2029 compared to its current production levels. The capacity increase centers on multi-core fiber, which utilizes multiple light-carrying glass strands within a single cable to increase overall network throughput.
The players
Lightera
A developer and manufacturer of optical fiber infrastructure, focused on scaling production for high-capacity network hardware.
The details
Lightera is deploying capital to increase throughput at its established hubs in Brondby, Denmark and Norcross, Georgia. Multi-core fiber is an optical cabling architecture where multiple individual glass cores are embedded within the same protective cladding, allowing for higher data density than traditional single-core designs. By scaling these specialized manufacturing lines, the company is preparing for a transition toward high-density fiber deployments in enterprise and cloud data centers.

2029: Target date for achieving a 3x increase in manufacturing capacity.
The Tech Race
This production expansion marks a foundational step in moving multi-core optical fiber from research-stage networking architectures to mass-market availability. As data centers push for higher throughput, the field is racing to standardize multi-core cabling as the successor to single-core fiber.
The transition to multi-core fiber will eventually allow data centers to support higher bandwidth with smaller cabling footprints, reducing the physical complexity of network hardware. While the capacity increase is planned through 2029, its immediate impact is localized to industry supply chains.
The takeaway
Lightera is betting that multi-core infrastructure will become the standard for high-bandwidth data environments within the decade. Observers should track the company's 2029 capacity milestones to gauge the speed of adoption for multi-core fiber across global cloud data centers.
