Fiber to the Unit (FTTU) Retrofits

Upgrade every apartment home with fiber, without a gut rehab.

Internet Subway retrofits occupied multifamily communities with discreet, code-compliant fiber to each unit. We partner with Lightera and often deploy their InvisiLight® solutions to bring fiber deeper into buildings quickly and cleanly. Our team uses a broad toolbox of retrofit techniques to fit any property type or construction style—garden, mid-rise, high-rise, student housing, historic, or adaptive reuse.

Riser & equipment rooms

Clean, code-compliant MDF/IDF buildouts, power, grounding, racks, OLTs/switches.

Fiber drops to each unit

Discreet pathways to the demarcation point inside every home.

ONT placement & turn-up

Optical Network Terminal placement, signal qualification, and speed/latency tests.

Resident activation & support

Door-to-door scheduling, communications, and white-glove install experience.

Resident activation & support

Labeling, test records, schematics, photos, and maintenance plan.

Because no two buildings are alike, we select the right mix of tools for each property:

We meet the building where it is—wood frame or concrete, new or 1970s—and deliver a clean, durable fiber path to every unit.

Timeline & disruption

Project durations vary by size and construction. We stage work by building/stack and coordinate with management to minimize interruptions. In-unit time is typically brief and scheduled—most residents are back to normal the same day.

Frequently Asked Question

Do residents need to be home?
For in-unit entry, yes; we offer scheduled windows and building-by-building notices.
Our first choice is low-visibility pathways (e.g., InvisiLight®). Where concealed routes are required, we patch/paint to deliver a clean finish.
Yes. We can operate alongside incumbents during transition and cut over building-by-building.
We tailor methods—surface raceways, micro-pathways, or exterior/conduit solutions—to meet code and aesthetic requirements.
 Yes. Fiber provides the bandwidth and reliability your proptech stack needs today and in the future.
