Surge protection for up to 1.5 Gbps<\/strong><\/h2>\n\n\n\n

As telecommunications connections speed up and the active technology (e.g., router) is now moving into meter cabinets, protecting these devices from surge voltage is crucial for stable operation even during thunderstorms. The surge protection should be easy to install and not impair transmission.<\/p>\n\n\n\n\n\n\n

\n

No fear during a storm<\/strong><\/h2>\n\n\n\n

Modern telecommunications devices are essential at home and in the office. Ensuring their unrestricted operation is now an absolute necessity. Using appropriate surge protection prevents unexpected failures due to voltage peaks. Besides power supply protection, VDE 0100-443 standard and TAR VDE-AR-N 4100 recommend protecting the communications interface. With many telecommunications systems available, which protective device is suitable?<\/p>\n\n\n\n

DSL interfaces and their transmission speeds<\/strong><\/h2>\n\n\n\n

DSL interfaces provide Internet speeds from 16 Mbps (ADSL2) to 300 Mbps (super-vectoring VDSL\/SVVDSL). Vectoring VDSL reduces crosstalk interference in copper telephone cables. Transmission frequencies range from 2.2 MHz (ADSL) to 35 MHz (SVVDSL), important for selecting protective devices with matching cut-off frequencies. Manufacturers should specify both cut-off frequency and maximum DSL speed. G.fast offers speeds up to 2 Gbps over very short copper lines (<100 m).<\/p>\n\n\n

Suitable protective devices<\/strong><\/h2>\n\n\n\n

To prevent signal from being influenced, attenuation at high frequencies must be negligible. High-speed data transmission, especially with super-vectoring, requires symmetry of the copper wires against ground. The DT-TELE-WM-RJ45-PT-I product<\/a> ensures minimal impact on transmission quality, even at 300 Mbps (VDSL) and 2 Gbps with G.fast. Deutsche Telekom tests confirmed its excellent transmission behavior and compatibility with VDSL, VVDSL, SVVDSL, and G.fast.<\/p>\n\n\n\n

Quick and easy installation<\/strong><\/h2>\n\n\n\n

The DT-TELE-WM-RJ45-PT-I can be easily snapped onto a DIN rail or mounted on a flat surface or perforated board using pull-out tabs. Its electrical connection is flexible and user-friendly due to the combinaton of Push-in technology for installation cables and RJ45 jacks for assembled telephone cables.<\/p>\n\n\n

Protection against incorrect installations and power-cross<\/strong><\/h2>\n\n\n\n

If a cable with too high a voltage is connected to the connection terminal blocks, the integrated current sensors limit the current and voltage to safe levels. Once the error is rectified, the sensors return to normal. Even in extreme cases, like a power-cross or a 230 V AC line connection, the DT-TELE-WM-RJ45-PT-I protects the end device (e.g., router) and remains in a safe state.<\/p>\n\n\n\n

In case of thermal overload, an internal disconnect device disconnects the affected protective element from the data line. A red status indicator signals that the DT-TELE-WM-RJ45-PT-I needs replacement as its protective function is compromised. This surge protection limits high pulse voltages and harmful energy from miswiring, preventing damage to the TC device.<\/p>\n\n\n\n

Required performance<\/strong><\/h2>\n\n\n\n

The IEC 61643-22 standard provides information on the required performance of protective devices, specifying surge voltage categories (D1, C2, C1) based on installation location. Standardized testing verifies these properties. Well-documented devices provide data for various standard pulses, reflecting installation location. For example, devices at the building entrance (first lightning protection zone) should meet category D1 requirements, while subsequent levels should meet C2 and C1. The described protective device meets all these categories and can be used in any lightning protection zone.<\/p>\n\n\n
