QUIET-TEL® noise mitigation equipment

If you are troubleshooting customer complaints about noise or electrical interferences on copper data transmission wires, our QUIET-TEL® solution may be for you. SNC Manufacturing is the industry leader and primary provider of single and multi-pair noise solutions. QUIET-TEL® controls AC-induced voltages and harmonics on copper ICT lines, as well as other sources of electrical interference, including 60-cycle hum, DSL noise, pixilation, tiling and more. This communication product also solves issues with slow data transmission over a modem.

SNIX Single Noise Interference Xterminator

The SNIX is a specially designed UL-listed filter for single-circuit applications to help suppress common telephone line problems.

Standard Induction Neutralizing Transformers

An induction neutralizing transformer is a simple, passive device that splices in series with the cable. It’s used to mitigate induced AC voltages, currents or harmonics that may be causing noise or equipment malfunctions or damages.

Digital Induction Neutralizing Transformers

Digital Induction Neutralizing Transformers, or DINTs, are similar to standard INTs, except they have a double-wound core to lower decibel loss. They have two separate groups of pairs, one for each transmission direction. The pairs are separated by an electrostatic shield to minimize crosstalk coupling.

TEN – Transformer Exciting Network

The TEN is a drainage reactor, specially designed for either 50 Hz or 60 Hz. It is easily bridged across one working circuit, providing a low impedance path-to-ground for longitudinal power line-induced interfering current to flow.
