MDU Fiber Drop Installation to Every Unit
Unit-level fiber drops installed and OTDR-tested to carrier specifications. ASI handles the last connection in the MDU build, from riser to unit entry, across the NY Metro and Northeast.
What We Do
The Last Mile Inside the Building
Fiber drop installation is the final phase of the MDU build, connecting the distribution network in the riser and hallways to each individual unit. It's the phase that produces the actual unit count the carrier is reporting to the owner, and the quality of the drop installation determines whether those units pass testing and stay online.
ASI installs unit-level fiber drops as part of the complete MDU scope, working off the riser and hallway infrastructure already in place. Every drop is installed with proper bend protection, correct termination at the unit entry point, and OTDR-tested to confirm signal quality before we mark the unit complete.
We work in occupied and unoccupied buildings alike, and we sequence drop installations by floor and wing to minimize tenant disruption while keeping the build moving at a pace that meets project milestones.
"Every unit signed off. Every drop tested. No exceptions."

How We Approach It
Drop Installation Process
Drop installation is where the unit count gets built. Here's how ASI works through it floor by floor.
Floor Sequencing Plan
Before drops start, we confirm the floor-by-floor sequence with the project manager and, for occupied buildings, coordinate with the property manager on tenant notification. No surprises for residents mid-installation.
Distribution Point Prep
Each floor's riser distribution point is confirmed and ready before the drop crew begins. Drop counts are verified against the unit layout so we're not discovering discrepancies unit by unit.
Drop Cable Installation
Fiber drop cable is pulled from the distribution point through the hallway raceway to each unit entry. Cable is managed cleanly at every transition, and bend radius is maintained throughout the run.
Unit Entry Termination
Drops are terminated at the unit entry point to carrier specifications. Termination hardware is installed correctly the first time, so testing isn't delayed by rework at the connection point.
OTDR Testing & Sign-Off
Every drop is OTDR-tested after installation. Test results are recorded per unit. Units that don't pass are addressed immediately before the crew moves to the next floor. Project closeout documentation includes test records for every unit in the building.
Why It Matters
Unit Count Only Matters If Every Unit Actually Passes
The metric a carrier reports at MDU project closeout is units passed and tested, not units where cable was installed. A drop that fails OTDR testing is a unit that doesn't count until it's fixed, and fixing it after the crew has moved on is expensive and slow.
ASI builds testing into the drop phase, not onto the end of it. Each unit is tested as the crew works through the floor, so any issues are identified and corrected before the next floor begins. That approach keeps the project timeline intact and delivers accurate unit counts at closeout.
What We're Known For
-
Test-as-you-go discipline. OTDR testing happens per unit as the floor progresses, not as a batch at the end. Problems are caught and corrected in sequence.
-
Occupied building experience. We've worked in occupied NYC metro buildings. Tenant coordination, hallway noise management, and keeping common areas accessible are standard practice for our crews.
-
Accurate unit-by-unit records. Test results and as-built records are maintained per unit, not per floor or per building. The documentation reflects exactly what's installed and what was tested.
-
Carrier-spec termination. Unit entry terminations are done to the carrier's specifications, not a general standard. The network operator can hand off to their activation crew without rework.
