Product Description

The Comtest Bonded EMI Suppressor is a Common Mode EMI Filter designed and universally built for all DSL services including single line VDSL2 and Bonded. This dongle will reduce or eliminate the effects of EMI on a single VDSL2 or both pairs of a DSL bonded service.

Differential signaling is used in telecommunication utilizing twisted pairs. One of the main advantages of differential signaling is increased resistance to electromagnetic noise. Resistance to electromagnetic noise is achieved only if twisted pairs are well balanced. Unfortunately, In the real word, twisted pairs are not perfectly balanced. As a result, interfering signals on Tip and Ring are not the same in amplitude and phase. Coupled signals on Tip and Ring will not be cancelled. And therefore, electromagnetic noise (EMI) has a detrimental effect on DSL lines, reducing the usable bins and creates errors.

This Comtest bonded EMI Suppressor works on both pairs to reduce or eliminate this noise and provides insertion loss of 30dB of couple signals (Electromagnetic interference signals) without adversely affecting the bonded DSL signal.
