Structured Cabling
Scalable cabling, fiber, and IT systems engineered for performance, redundancy, and future expansion — the physical foundation that everything else in your network depends on.
The infrastructure everything runs on
Cabling is the part of a project that nobody sees, and everybody feels when it’s wrong. We’ve worked in enough commercial construction environments to know that a cabling system installed without a plan becomes someone else’s problem six months later, usually during a build-out, a renovation, or a system upgrade. Legacy Data Technologies plans and installs structured cabling systems that are designed to last, documented for clarity, and built to be worked on by whoever comes after us.
Core Capabilities
Copper cabling systems
CAT5e, CAT6, and CAT6A horizontal and backbone cabling installed and certified to TIA/EIA standards for voice, data, and PoE applications.
Fiber optic networks
Single-mode and multimode fiber for high-speed backbone connections, campus-wide distribution, and long-distance runs where copper falls short.
Data center cabling
High-density structured cabling for server rooms and data centers, including patch panel organization, cable management, and hot/cold aisle containment support.
Outside plant & campus fiber
Aerial and underground fiber runs connecting multiple buildings or campuses — including conduit installation, vault work, and splice enclosures.
Testing & certification
Every run is tested and certified to manufacturer and industry standards using calibrated Fluke equipment — documented results provided for your records.
Moves, adds & changes
Structured support for reconfigurations, office relocations, expansions, and upgrades — without disrupting the rest of your operating environment.
Cabling decisions made early in a project define what’s possible for years afterward. Our teams work alongside your IT, security, and AV stakeholders from the design stage — so the infrastructure we install supports every system you run today and every one you’re planning for.
Fiber Vs. Copper — Choosing The Right Medium
Both fiber optic and copper cabling have a place in a well-designed infrastructure. Our engineers assess your environment and application requirements to recommend the right solution — or the right combination — for each part of your network.
| Fiber Optic — High-speed, long-distance runs | Copper (CAT6/6A) — Local device & workstation runs |
| + Extremely high bandwidth capacity | + Cost-effective for horizontal cabling |
| + Immune to electromagnetic interference | + Supports Power over Ethernet (PoE) |
| + Transmits reliably over long distances | + Easy to terminate and reconfigure |
| + More secure — harder to tap undetected | + Compatible with all standard network gear |
| + Ideal for backbone and campus links | + Sufficient for most in-room deployments |

Industries We Serve
Network reliability requirements are universal, but the specifics vary enormously — a hospital’s cabling infrastructure has to support life-critical systems, while a fintech firm’s needs to handle massive data throughput with zero tolerance for downtime. We design for the demands of each:
- Corporate Offices & Campuses
- Financial Services & Banking
- Healthcare & Life Sciences
- Government & Public Sector
- Educational & Universities
- Enterprise Corporations
- High-Growth Tech Companies
- Retail & E-commerce
- Warehousing & logistics
Designed to Grow With You
The most expensive cabling project is the one that has to be redone. Our approach accounts not just for where your network is today, but where it will be in five to ten years — factoring in expected device growth, bandwidth demands, PoE expansion, wireless density, and the systems you haven’t yet deployed.
All infrastructure is documented thoroughly with labeled ports, as-built drawings, and certified test results so that future changes — whether made by our team or another — can be executed accurately without guesswork.
Planning a new facility or expanding an existing site?
Our team will assess your environment and design a cabling solution built for what comes next — from a single floor to a multi-building campus.
We serve commercial clients across the New York metropolitan area, including new construction, renovation, and ongoing facility service.
