Full Control Over Your Fiber Core Infrastructure
GENXPLUS leases dedicated dark (unused) optical fiber cores to ISPs, internet resellers, and enterprises — giving you complete control over bandwidth, protocols, and scalability on a secure, high-capacity backbone network.
What is Dark Core Connectivity?
Dark Core Connectivity refers to the leasing of unused (dark) optical fiber cores — physical fiber strands that carry no active signal until the client deploys their own transmission equipment. GENXPLUS provides the raw fiber infrastructure while clients retain complete freedom to choose their own active equipment, protocols, and bandwidth capacity.
This model gives ISPs, internet resellers, and enterprises maximum flexibility — enabling backbone networks, intercity links, and critical communication routes with no dependency on shared infrastructure or third-party active equipment.
GENXPLUS maintains the physical fiber layer — including duct systems, joint enclosures, and route integrity — so clients can focus entirely on building and scaling their own network on top of a robust, reliable fiber foundation.

Everything GENXPLUS manages for you
While clients control the active network layer, GENXPLUS takes full responsibility for the physical fiber infrastructure — from provisioning and deployment to ongoing maintenance and emergency response.
Fiber Core Provisioning
End-to-end dark fiber core provisioning across GENXPLUS's established optical fiber network — allocating dedicated, exclusive fiber strands for each client's specific route requirements.
Route Planning & Fiber Allocation
Expert route planning and strategic fiber allocation to ensure optimal path selection, redundancy options, and the most efficient use of the fiber network for the client's connectivity needs.
Splicing, Termination & Testing
Professional fiber splicing, precise termination, and comprehensive optical testing including OTDR analysis — ensuring optimal signal performance and zero compromise on fiber quality before handover.
Physical Infrastructure Maintenance
Ongoing maintenance of all physical fiber infrastructure including duct systems, joint enclosures, manholes, and route structures — ensuring the fiber layer remains robust and structurally sound.
OTDR & Loss Measurement
Periodic OTDR testing and optical loss measurement across the fiber route to detect signal degradation, identify splice quality issues, and ensure consistent, high-quality transmission performance.
Route Inspection & Fiber Health Checks
Regular physical route inspections and fiber health assessments to identify potential risks such as third-party dig work, environmental damage, and structural vulnerabilities along the fiber path.
24/7 Monitoring Support
Round-the-clock monitoring of the optical fiber infrastructure to detect anomalies, signal degradation, and potential faults — enabling proactive intervention before clients are impacted.
Fault Localization & Restoration
Rapid fault localization using OTDR and field inspection techniques, followed by swift fiber restoration services within defined SLA response and resolution timelines.
Technical Assistance & Coordination
Prompt technical assistance and coordination support for any operational challenges — helping clients navigate infrastructure-related issues with expert guidance from our experienced team.
What you control vs. what we manage
Dark Core Connectivity is a partnership model — clients have full autonomy over the active network while GENXPLUS ensures the physical fiber layer is always reliable and secure.
You Control the Active Layer
As the dark fiber client, you have complete ownership and freedom over all active equipment, network protocols, configurations, and bandwidth management — with no interference from GENXPLUS on the active network side.
- Deployment of own transmission equipment
- Bandwidth capacity and protocol selection
- Network configuration and routing
- Traffic management and QoS policies
- Active equipment maintenance and upgrades
- Network scalability planning and execution

- Fiber core provisioning and allocation
- Duct systems and joint enclosure maintenance
- Periodic OTDR testing and health checks
- Fiber route inspection and integrity monitoring
- Fault localization and fiber restoration
