More About GCX
Global Cloud Xchange (GCX) operates an international network that combines subsea cable systems with terrestrial fiber to support connectivity requirements for carriers, hyperscalers, content providers, and enterprises. Its assets System Integration Testing (SIT) on primary traffic corridors linking Europe, the Middle East, and Asia, with onward connectivity into other regions via partner and interconnection arrangements. The company positions its infrastructure for use cases such as cloud access, content distribution, and enterprise Wide Area Network (WAN) architectures that depend on predictable latency and capacity across long-haul routes.
GCX’s subsea systems (subsea transport) are built around high-capacity fiber pairs, using optical transmission technologies and protocols typical of modern long-haul networks, such as Wavelength Division Multiplexing (WDM) and Ethernet-based services. On top of this physical layer, the company offers bandwidth and transport services that can be integrated into carrier backbone designs or used by cloud and content providers to extend their own networks. By combining subsea and terrestrial segments, GCX supports end-to-end routes that connect landing stations with carrier hotels, data centers, and major internet exchange locations.
On the terrestrial side (network infrastructure), GCX provides backhaul, metro, and regional connectivity that ties its landing points into core interconnection hubs. These services can be consumed as point-to-point links, regional rings, or as components within multi-region Multiprotocol Label Switching (MPLS), IP, or Ethernet networks designed by customers or partners. The company’s infrastructure commonly interfaces with standard enterprise and carrier network architectures, including hub-and-spoke, mesh, and hybrid models that blend private transport with public internet and cloud on-ramps.
GCX also offers managed services (managed connectivity), where it provides monitoring, operations, and lifecycle management for connectivity solutions. This can include Service Level Agreements (SLAs) for availability and performance, Network Operations Center (NOC) oversight, and support aligned to ITIL-style service frameworks. Enterprises and service providers can use these services to offload day-to-day management of long-haul and cross-border circuits while maintaining control at the logical and application layers.
Cloud-connect and DCI offerings (cloud connectivity) enable customers to connect from on-premises (on-prem) or regional sites into major cloud platforms and multi-tenant data centers. These services are typically integrated through standardized Ethernet and IP services and may be used alongside Software-Defined Wide Area Network (SD-WAN) and hybrid cloud architectures implemented by customers. Within an enterprise or institutional environment, GCX’s portfolio is often categorized under global network infrastructure, subsea and terrestrial transport, and managed connectivity services, and it is positioned as one of the underlay options that support higher-level collaboration, application delivery, and cloud networking solutions.
