Depending on what's already in the conduit, UTP will probably work fine. I would definitely just pull fiber and avoid STP completely if EMF is an issue, or if you're thinking of expanding anything.

Unshielded (UTP) and Shielded (STP) Twisted pair cables are available unshielded (UTP) or shielded (STP), with UTP being the most common.

For DVI and HDMI, equalizer designs center on twisted-pair cable, whether it may be a dedicated cable or generic Category-style UTP/STP cable. The compensation gain curve (or transfer function) ...

UTP significantly lowers the barrier to entry for 10GBaseT compared to fiber and STP, and the availability of reliable UTP-based equipment is expected to catalyze adoption of 10-Gigabit Ethernet ...

The new system is shock and vibration resistant, and is intended for UTP and STP applications. Compatible with Cat-5e and Cat-6 use, the connector uses a screw mating system to ensure a secure ...

Unshielded twisted pair (UTP) [and its cousins, foiled twisted-pair (FTP) and shielded twisted-pair (STP)] are balanced transmission lines. They are inherently immune to interference.

Lesson Six, Iowa State Telecom installation correspondence course: cable termination practices are vital for transfer of information. Insulation Displacement Connection (IDC) termination is the ...

The Lantek 6A is a cable certifier designed specifically to test Cat. 6a and ISO Class Ea (augmented) UTP and STP cabling, expected to be ratified by the Telecommunications Industry Association and ...

Designed for use on structured cabling systems, the Quintest can be used for both STP and UTP cables as well as installed networks. It features an automatic test for screen, thus eliminating the ...
