Structured cabling & fiber
Every network sits on cable, and cabling outlives the equipment above it by decades. ANSI/TIA-568 defines how commercial buildings are cabled: horizontal runs to the desk, backbone runs between closets, permanent links and channels. For copper we work with Category 6A, which carries 10 GbE over 100 m, and we label, document and certify every run so that faults can be found later.
What we do
- Cabling design to TIA-568 for offices, data halls and plants
- Cat6A runs certified and documented to link level
- OM4/OM5 and OS2 fiber plant design
- MPO/MTP trunk, cassette and polarity planning
- OTDR and insertion-loss test reports
- PoE power-budget and heat checks for 802.3bt devices
- Pathway, labeling and as-built documentation
- Remediation of failing or undocumented legacy cabling
- Cable-management and patching standards so racks stay serviceable
For fiber, multimode (OM3, OM4, OM5) suits short links inside a building or data hall: OM4 is rated 3500 MHz.km at 850 nm and OM5 adds a second wavelength for short-wave WDM. Single-mode (OS2) carries longer links between buildings and sites. In data centers, MPO/MTP connectors bring 8, 12 or 24 fibers in one plug for 40, 100 and 400 Gb/s parallel optics, so polarity and cleanliness are managed carefully.
Testing proves the work. A copper certifier measures a link against its category; an optical time-domain reflectometer (OTDR) sends pulses into the fiber and plots the returning light to locate breaks, high-loss splices and reflective events. IEEE 802.3bt carries power over four pairs for access points, cameras and phones, so cable gauge, bundle heat and switch power budgets are checked at design time.

How we use Structured cabling & fiber for clients
Frequently asked questions
Direct answers to the questions we hear most. Something else on your mind?
Send us a messageHow long does structured cabling last?
Cabling commonly outlives the equipment above it by decades, which is why it is designed to ANSI/TIA-568 and documented. Choosing Category 6A copper and OS2 single-mode now avoids re-pulling cable when switches change, though the choice affects upfront cost.
Why choose Category 6A instead of Category 6?
Category 6A carries 10 GbE over the full 100 m channel. Category 6 reaches 10 GbE only over shorter runs, about 55 m according to the 10GBASE-T guidance. Higher categories also help with PoE heat in bundles.
What does an OTDR test show that a power meter does not?
An optical time-domain reflectometer sends pulses into the fiber and plots the returning light, so it locates breaks, high-loss splices and reflective events along the length. An insertion-loss test gives the total loss. We use both and give you the reports.
When do we need MPO/MTP connectors?
For parallel optics in data halls, where one plug brings 8, 12 or 24 fibers for 40, 100 and 400 Gb/s links. They need careful polarity planning and cleaning, and a polarity mistake can mean a link that will not come up.
How do we check PoE before installing access points or cameras?
IEEE 802.3bt carries power over four pairs, so we check cable gauge, bundle heat and the switch power budget at design time, not after the devices fail to power up. Long runs and large bundles raise the temperature and reduce margin.
What if our existing cabling is undocumented or failing?
We test it, label it and report which runs pass their category and which fail. Failing runs are remediated and the as-built documentation is delivered, so faults can be found later instead of traced by hand.
