Diversity that survives scrutiny
Two circuits are not diverse when they share an entrance, handhole, bridge, or civil corridor. DRDI reviews the physical path, not just the carrier names.
Industry
Data Centers & Colocation
Dedicated fiber infrastructure for data-center operators, colocation providers, and tenants that need direct regional reach with a route they can evaluate.
The operating reality
Interconnection without hidden path assumptions.
A data center is only as useful as the pathways that reach it. Power, cooling, and space may live inside the facility, but application performance, customer choice, and expansion velocity depend on what happens outside the walls.
DRDI gives operators and tenants a transparent way to plan that physical layer. Our completed underground network connects CoreSite DC2 in Washington and TierPoint BWI today, with downtown Baltimore extensions planned for December 2026. We qualify entrances, handoffs, shared-risk points, construction scope, and restoration ownership before treating a location as serviceable.
Faster qualificationA clear route review and a 30-day target for qualified on-net delivery.
Capacity runwaySixteen ducts with capacity for 864 fibers per duct across the system design.
Operational ownershipOne white-glove team from feasibility through turn-up and 24/7 monitoring.
What makes the network difficult
Build around the pressure points.
The strongest design starts with the physical and operational constraints that can interrupt the mission, not a generic bandwidth recommendation.
Facility coordination
Cross-connects, meet-me-room rules, letters of authorization, entrance capacity, and building access can control the schedule. They belong in the delivery plan from day one.
Capacity without repeat construction
Growth is easier when fiber pairs or conduit can be reserved against a known roadmap instead of restarting a civil project every time demand increases.
Common applications
Where dedicated infrastructure changes the equation.
Every location remains subject to detailed serviceability, entrance, route, and commercial review.
- Data-center interconnection and replication
- Cloud and carrier on-ramp access
- Tenant and customer fiber extensions
- Business continuity and recovery paths
- Campus-to-colocation connectivity
- New facility entrance and lateral construction
Match the asset to the requirement
Three ways to control the path.
DRDI can combine dedicated strands, reserved conduit, and new construction when different parts of the project require different ownership or expansion rights.
DRDI solution
Dark Fiber
Dedicated strands for customers that want to own the optics, select the transmission platform, and scale capacity on their schedule.

Dedicated pathway control for operators planning multiple cables, long capacity horizons, or infrastructure they intend to manage directly.

Evaluate the path, responsibilities, and operating model.
- Which building entrances and meet-me rooms can support the proposed design?
- Where do primary and backup paths share conduit or civil structures?
- Who coordinates cross-connects, access, splicing, testing, and acceptance?
- What fiber or conduit can be reserved for future tenants and expansions?
Practical answers
Questions we expect early.
Can DRDI connect a facility that is not currently on-net?
Potentially. We review the distance to the completed network, construction conditions, entrance options, schedule, and commercial structure before proposing an extension.
Who supplies the optics for a dark-fiber connection?
The customer supplies and operates the optical equipment. DRDI delivers and maintains the contracted passive fiber path as defined in the service agreement.
Does a map line prove route diversity?
No. Diversity must be reviewed against the detailed physical alignment, entrances, handholes, crossings, and other shared-risk points.
