Data Center Structured Cabling Services_
Data center structured cabling services for GPU clusters and AI-scale data centers. OM4, OM5, OS2 fiber, MPO/MTP trunking, DAC, AOC, and AEC interconnects — all installed to TIA-942, TIA-568, and BICSI standards. Over 25,000 cable connections deployed and tested across Texas and the United States.
Why Cabling Matters in GPU Infrastructure_
In a GPU cluster, the network fabric is compute performance. NVLink connects GPUs within a node. InfiniBand or high-speed Ethernet connects nodes across the cluster. Every cable in the fabric is a link in a chain — one bad connection, one marginal fiber, one improperly seated connector degrades the performance of the entire system.
GPU-dense environments compound this. A single GB200 NVL72 rack can have hundreds of individual cable connections. A 100-rack deployment means tens of thousands of connections, each one tested and documented.
This is not general-purpose data center cabling. The density, the speed, and the cost of errors demand specialization.
Scope of Work_
Fiber Installation
OM4 and OM5 multimode fiber for short-reach GPU-to-switch connections. OS2 single-mode fiber for backbone runs and long-distance links. All fiber routed per pathway design with proper bend radius and protection at transition points.
MPO/MTP Trunking
High-density trunk cables with 8, 12, or 24 fibers per connector for GPU cluster fabrics. Pre-terminated, factory-tested trunks reduce installation time and produce cleaner pathways than individual fiber runs.
DAC, AOC, and AEC Interconnects
DAC for short-reach, low-latency connections within a rack. AOC for runs that exceed DAC distance limits. AEC for extended copper reach with signal conditioning. We select the correct interconnect type based on topology and performance requirements.
Copper Infrastructure
Category 6A and Category 8 copper for management networks, BMC/IPMI out-of-band connectivity, and facility infrastructure. Terminated, tested, and documented to TIA standards.
Cable Management
Every cable routed through designated pathways, dressed to avoid stress and interference, and secured with proper supports. Cable management in GPU environments is a functional requirement for future maintenance and troubleshooting.
Labeling & Documentation
Every cable labeled at both ends with a naming convention aligned to the network topology. Port-to-port maps, cable schedules, and as-built documentation delivered at handoff.
Cable Types & Applications_
| Cable Type | Application | Typical Distance | GPU Context |
|---|---|---|---|
| OM4 Multimode | GPU-to-switch, short fabric runs | Up to 150m at 100G | Standard for intra-row GPU connectivity |
| OM5 Multimode | Wideband multimode, short-wave WDM | Up to 150m at 100G | Future-proofing for higher lane counts |
| OS2 Single-mode | Backbone, cross-connect, long runs | Up to 10km+ | Data center backbone and inter-building links |
| MPO/MTP Trunk | High-density multi-fiber bundles | Varies by fiber type | GPU cluster fabrics with hundreds of links per rack |
| DAC | Direct copper connection | Up to 5m | Intra-rack or adjacent rack GPU-to-switch |
| AOC | Active optical, pre-terminated | Up to 100m | Mid-range runs where DAC cannot reach |
| AEC | Active electrical, extended copper | Up to 7m | Extended reach with copper simplicity |
How We Work_
Site Survey & Pathway Design
Review the fabric design, rack elevations, and pathways. Confirm cable types, trunk counts, and routing before any cable is pulled.
Rough-In & Pathway Build
Install cable tray, ladder rack, and containment. Stage trunks and reels to the pathway plan.
Termination & Dressing
Pull, terminate, and dress fiber and copper to bend-radius and separation rules. Label every cable at both ends.
Test & Certify
Fiber inspected to IEC 61300-3-35 and tested for insertion and return loss; copper certified to the category standard.
As-Built Handoff
Deliver port-to-port maps, cable schedules, test results, and as-built documentation to the operations team.
Standards We Work To_
All work is performed to ANSI/TIA-942 (Telecommunications Infrastructure Standard for Data Centers) and ANSI/TIA-568 (cabling components and field testing), with BICSI installation practices. This governs pathway design, cable separation, bend radius, labeling, testing, and documentation.
Fiber terminations are inspected to IEC 61300-3-35 end-face cleanliness before mating — the single most common cause of link loss on high-speed fabrics. Labeling and administration follow ANSI/TIA-606.
Platform coverage: cable plant built for H100, H200, GH200, GB200 NVL72, and GB300 NVL72 GPU clusters.
Where we work: based in Texas, deploying data center structured cabling services across the United States.
Track Record_
GPU cluster fabrics built for: H100, H200, GH200, GB200 NVL72, and GB300 NVL72 platforms
OEM switching infrastructure: Arista deployed alongside Dell, NVIDIA, and Supermicro compute
Structured Cabling FAQ_
What does data center structured cabling include?
Data center structured cabling is the organized fiber and copper cable plant that connects servers, switches, and patch panels through defined pathways. Our scope covers OM4/OM5 multimode and OS2 single-mode fiber, MPO/MTP trunking, DAC/AOC/AEC interconnects, Category 6A and Category 8 copper, pathway and containment build, labeling, testing, and as-built documentation — all to TIA-942 and BICSI practice.
Do you work to TIA-942 and TIA-568 standards?
Yes. Installations follow ANSI/TIA-942 for data center infrastructure and ANSI/TIA-568 for cabling components and field testing, with BICSI installation practices for pathways, bonding, bend radius, and labeling. Fiber end-faces are inspected to IEC 61300-3-35 before mating.
Which cable types do you install for GPU clusters?
OM4 and OM5 multimode for short GPU-to-switch runs, OS2 single-mode for backbone and long runs, MPO/MTP trunks for high-density fabrics, DAC for intra-rack copper, AOC for mid-range optical runs, and AEC for extended copper reach. We select the interconnect by topology, distance, and platform — never one type for everything.
Do you test and certify every connection?
Every fiber link is inspected and tested for insertion loss and return loss, and every copper run is certified to its category standard. Marginal or failing links are re-terminated and re-tested. Full test data and cable maps are delivered in the as-built package.
Where do you provide data center cabling services?
Leviathan Systems is based in Texas and provides data center structured cabling services across the United States, mobilizing to AI and GPU-cluster sites nationwide.
