Data Center Cabling & Enterprise Network Design
Modern business demands a foundation that can handle massive data throughput without latency. TNG specializes in comprehensive network infrastructure design and installation, focusing on high-density data center cabling solutions. We don’t just pull cable; we architect systems. By utilizing Cat6 / Cat6a installation and high-capacity fiber optic installation services, we eliminate bottlenecks and ensure your hardware performs at its peak. Our designs are strictly compliant with TIA/EIA standards, providing the reliability required by government agencies, healthcare facilities, and enterprise corporations.

As one of the leading low voltage wiring companies, TNG provides the precision required for long-distance and high-speed data transmission. Our fiber optic solutions offer the backbone needed for modern cloud-based environments and multi-building campuses.

We ensure that every inch of your facility—from the server room to the furthest warehouse corner—is fully connected and signal-strong.
