Telephone filters are electronic devices designed to solve the noise and interference problems of telephone lines in shielded rooms and anechoic chambers. Inside a shielded enclosure, telephone lines increases the risk of external EMI coupling. WEMC telephone filter is installed in the area where the telephone line passes through the shielding wall. Through an advanced filtering technology, it can effectively filter the interference of high-frequency EMI and provide a clear and stable communication environment inside a shielded enclosure, while ensuring the smooth passage of the telephone signal.

With the increasing demands of communication technology and projects, the requirements for multiple phone lines in shielded enclosures arises accordingly. WEMC customize telephone filters up to 150 pairs inside a single case, with IEC plug-in terminals, easy to install on project sites. Each line provides independent filtering circuits, to make sure your shielded enclosure in an EMI-free environment.
