Nexloop France

What Nexloop France does

Nexloop France is a Cellnex Telecom subsidiary that operates a proprietary national fiber optic infrastructure platform coupled with a distributed Edge datacenter footprint. The company owns and operates more than 38,000 km of fiber across 75+ French metropolitan areas, with 130+ Edge datacenters and 8 points-of-presence providing low-latency, high-capacity connectivity across the country. Its service portfolio spans Fiber To The Office (FTTO), Dark Fiber, Wavelength Division Multiplexing (WDM) transport up to 400 Gbps, colocation/hosting and DC Connect inter-datacenter services, positioning it as a wholesale neutral-host B2B provider rather than a retail ISP.

The underlying technology combines long-haul and metropolitan fiber with optical transport and modular Edge facilities, enabling delivery of both raw infrastructure (dark fiber, ducts) and managed connectivity services (lit FTTO, WDM wavelengths, cross-connects). This integrated stack is designed to serve customers requiring dedicated capacity and geographic reach — including telecom operators, public-sector entities (RTE, Paris Habitat, Gigalis), financial, media, healthcare, energy and transport organizations, and IT service providers (HubOne, Axione, Foliateam, Prosoluce).

Nexloop's business model is enterprise and wholesale B2B, monetizing long-term contracts for fiber capacity, colocation and managed transport. The company is funded primarily through its parent Cellnex Telecom (more than €1B deployed, registered capital of €16.1M) and pursues an enterprise field-sales go-to-market. Strategic intent is to densify France's two largest economic regions (Île-de-France, Marseille) and broaden from 75 to 100+ agglomerations by end-2026, while layering WDM and Edge datacenter services to capture AI, cloud and hyperscaler-adjacent demand.

Recent moves9 records

Expansion highlights5 records

Emerging players

• Digital Realty: Global data center operator with French facilities offering colocation and interconnection services. Competes in datacenter hosting and high-capacity fiber interconnect segments where Nexloop's Edge Datacenter and DC Connect offerings also compete.
• Equinix: Global colocation and interconnection provider with significant French presence (multiple IBX datacenters). Partial overlap with Nexloop's Edge Datacenter hosting and DC Connect services, particularly in serving hyperscaler and enterprise interconnection demand.

Regional players

• Zayo Group: US-headquartered dark fiber and wavelength services provider with European operations. Comparable in dark fiber (FON) and WDM wholesale offerings, though geographically focused on North America and select European routes rather than nationwide French metro coverage.
• Colt Technology Services: European-focused fiber operator providing dedicated Ethernet, wavelength, and dark fiber services to enterprises and operators. Comparable in WDM and metropolitan fiber offerings, though operating across multiple European cities rather than focused national metro coverage like Nexloop.

Direct peers

• Altitude Infrastructure: French neutral fiber infrastructure operator (subsidiary of Altitude Group) deploying FTTH and FTTO across underserved French territories. Competes head-to-head in neutral-host wholesale fiber with similar RIP/operator customer segments and a comparable infrastructure-led business model.
• Axione: French wholesale fiber and infrastructure operator serving public initiative networks (RIP) and telecom operators. Direct competitor in the French neutral-host fiber space, with overlapping customer base in regional operators and public-sector connectivity. Notably listed as one of Nexloop's enterprise customers, indicating they also operate their own fiber infrastructure.
• Orange Wholesale (France): Wholesale division of Orange, France's incumbent telecom operator, providing fiber wholesale and dark fiber services to other operators and enterprises. Largest competitor in French wholesale fiber despite being a vertically integrated carrier with retail conflicts.

Broad incumbents

• Cellnex Telecom: Parent company and Europe's largest neutral telecom infrastructure operator (138,000+ tower sites across 12 European countries). Comparable as a wholesale infrastructure provider, though primarily in towers rather than fiber; provides strategic context for Nexloop's neutral-host model and capital backing.
• Bouygues Telecom: Major French telecom operator with extensive fiber network serving enterprise and retail customers. Broad incumbent offering bundled connectivity services across mobile, fixed, and enterprise; competes for enterprise fiber deals and represents a customer/competitor overlap depending on segment.
• SFR / Altice France: Major French fiber network operator under Altice France, with extensive enterprise and wholesale fiber footprint. Competes with Nexloop for enterprise dark fiber, WDM, and FTTO customers, and represents one of the consolidating telecom customers in Nexloop's target segments.
