Designing a low-voltage infrastructure for a data center demands a purpose-built approach to copper and fiber-optic pathways. It is not something that traditional electrical-first contractors are comfortable accomplishing. That’s because the goals, uses, and scaling issues are very different.
Once you understand the different needs and parameters, you’ll also realize why it is essential to introduce low-voltage planning from the very beginning of any new building or construction. Especially a data center whose entire operations, productivity, and profitability rely largely on the quality, reliability, and extendability of the copper and fiber-optic pathways.
Understanding the Objectives of Low-Voltage Infrastructure Design
The demands of a low-voltage IT network are clear and have little overlap with the design of an electrical wiring solution.
Design Considerations for Network Cabling Solutions
- Low voltage limitations
- High-data-density transmission
- Scales, adjusts, and evolves frequently
- Heat dissipation
- Electromagnetic interference (EMI) separation
- Serviceability and maintenance
- Technology refreshes
In comparison, traditional electrical wiring plans are designed for high-voltage power delivery with static loads and strict building codes. Once installed, electrical pathways are rarely changed. Which means aspects important to low-voltage networks, like serviceability/accessibility, are far less important.
Why Electric Pathways Don’t Work for Copper and Fiber Optic Cables
We’ve established that the objectives of electrical and low-voltage pathways are different. It’s equally important to understand that the physical installation methods are also incompatible. What’s good and required for electricity is not advantageous for low-voltage cable.
Pathways
Electrical conduit is often undersized to accommodate modern data environments. High-count fiber trunks, redundant routes, and future scalability require tray systems, sleeves, and pathways that are significantly more flexible than standard conduit runs.
Spatial Planning
Electric pathways prioritize walls, ceilings, and equipment rooms. Data centers are best served by clear horizontal distribution zones, overhead ladder racks, underfloor routing and deliberate rack-to-pathway alignment. Those techniques mitigate cable congestion and related issues, such as overheating and EMI.
Retrofitting and Scaling
If low-voltage wiring is run along with electrical wiring, any changes require installers to work around finished walls, packed ceilings, and structural constraints. The combination of these factors increases labor costs, slows deployment schedules, and raises the risk of signal degradation.
In extreme cases, poor network planning has led to some facilities becoming obsolete. The cost to improve, repair, or replace the low-voltage network becomes far greater than the building is worth. Both electrical wiring and data wiring serve crucial functions in a facility. One delivers power, while the other empowers operations. Neither should be undervalued or considered a place to cut corners when building, remodeling, or expanding a facility. Taking each into account on day one and having them handled by excerpt designers and installers will produce the best possible performance and the lowest long-term operating costs.
Start Your Low Voltage Design With The Right Experts
Low-voltage pathways should be considered from the start of your construction or remodeling project. It’s not enough to be early, though. You also have to work with the right people. Here is a list of titles and team members to include on your next project.
- Low Voltage Infrastructure Engineer
- Electrical Engineer
- Operations/Facilities Lead
- IT/OT stakeholder
The holy grail of people to include — if you have access to one — is a Registered Communications Distribution Designer (RCDD). They are specifically certified to design:
- Structured copper and fiber cabling
- Pathways, trays, ladders, racks, risers, sleeves, Meet Me Room (MMRs), and Intermediate Distribution Frames (IDFs).
- Large facility IT backbones
- Redundancy
- Segregation
- Growth planning
When searching for an RCDD, it’s a good idea to identify someone with industrial, large-scale, and mission-critical design experience. Many only have a background in commercial office network design. While similar, a large-scale project such as a distribution facility presents unique challenges that must be addressed. Primary among these is how long runs can be to maintain bandwidth speeds.
Important Questions for Selecting an RCDD
- Have you designed a distribution center or industrial complex before?
- Do you default to a tray/ladder rack over conduit for data pathways?
- How do you plan fiber counts and space capacity over 10–15 years?
- How do you segregate IT, OT, safety, and security networks?
- How do you design for ceiling congestion and rack alignment?
Strong RCDD candidates will be able to explain their solutions clearly and confidently. If you encounter a candidate who lacks confidence when addressing those questions, consider it a red flag.
