Belden Shielded Systems protect against EMI

At the heart of the Belden Shielded Systems is a shielded 'tool-less' modular jack.

The Keyconnect modular jack helps to reduce installation time and provide superior shielding performance without compromising the size and ease of use of the UTP connector, according to Belden.

The modular jack comes with a termination cap to prevent the untwisting of the pairs to endure the integrity of the transmission performance.

Other components of the system include: Belden Category 6 and 5e cables for networks where noise and interference is high; modular cords and pigtails for optimum electrical performance at component level; and 24- or 48-port Keyconnect Shielded Patch Panels for horizontal distribution or equipment terminations in data centres and telecommunications rooms.

Prior to introducing these systems, Belden said it conducted extensive internal testing procedures in line with relevant standards.

Tests covered more than 100 different cabling configurations, including short links, long links, worst cases and most demanding four connector channel configurations.

These tests were performed at frequencies of up to 250MHz.

All transmission parameters were tested, including attenuation, Next, Fext and Return Loss.
