Every Unit.
Every Floor.
Done Right.
ASI Fiber Group provides complete MDU fiber installation for multi-dwelling units across the Northeast, from core drilling and riser installation to hallway drops and OTDR testing. One contractor. Every phase.
Full-Scope MDU Fiber Installation
MDU fiber installation is some of the most complex work in fiber optic construction. Tight spaces, occupied buildings, and multiple access points demand precision at every stage. We handle it all in-house, with no subcontractors on core scope.
Core Drilling
Precise core drilling through concrete floors, walls, and structural elements to create pathways for riser cables and conduit runs. Completed with minimal disruption to building occupants.
Riser Installation
Vertical cable runs from the building entry point to each floor. We design and install fiber riser systems that are clean, code-compliant, and built for future capacity.
Conduit Runs
Interior conduit installation from basement telecom rooms to individual floors and units. Properly rated, cleanly routed, and documented for as-built records.
Hallway Molding
Surface-mounted cable management through hallways when conduit isn't available. Clean, professional installation that meets building standards and keeps aesthetics intact.
Drop Installations
Unit-level fiber drops from riser or hallway terminals to the subscriber's ONT location. Each drop is routed cleanly and terminated to spec, ready for service activation.
Lock Boxes & Secure Access
Installation of lock boxes and access hardware to protect network equipment in common areas. Proper enclosures for splitter cabinets, terminals, and distribution points.
MDU Fiber Installation Fails When the Contractor Doesn't Know the Work
Most multi-dwelling unit fiber problems trace back to poor planning, unqualified crews, or contractors who don't have experience inside occupied buildings. Here's where we protect your project.
Occupied Building Coordination
We've worked inside occupied apartment buildings and residential towers throughout the Northeast. Our crews schedule around tenants, minimize access disruptions, and keep management informed at every stage.
Testing on Every Drop
We perform full bidirectional OTDR testing on every project. Every splice is documented and verified before we call the job complete. You get complete as-built records, not just a verbal sign-off.
Single Point of Accountability
One contractor from engineering through final documentation. No handoffs between subs, no finger-pointing when something doesn't test right. Our team owns the outcome start to finish.
Background in Carrier-Grade Work
Our leadership team comes from Altice USA, Cablevision, and Charter. We've done this work at scale for the largest carriers in the Northeast. That institutional knowledge shows in how we build.
From Site Walk to As-Builts
Every MDU project follows a structured process that keeps scope, schedule, and quality aligned from day one.
Site Assessment
We evaluate the building, document existing pathways, and identify the optimal entry and distribution architecture.
Engineering & Design
Splice design, conduit routing, and equipment placement developed before a single tool is picked up.
Construction
Core drilling, riser and conduit installation, hallway molding, and drop builds executed by our in-house crews.
Splicing & Testing
All splicing performed in-house. Bidirectional OTDR testing on every drop before sign-off.
As-Built Delivery
Final documentation package delivered. Complete records of every run, splice, and test result.
What Sets Our MDU Fiber Installation Apart
