4-channel Gigabit Ethernet surge arrester module, PTU-64-EXT/PoE

Module with dual functionality, designed to protect Gigabit LANs against the effects of overvoltages and lightning discharges. It is built on the basis of a multi-layer PCB with carefully designed printed circuits. Durable components of small dimensions and dedicated RJ-45 sockets of 6th category , ensure excellent transmission quality and high big surge currents resistance. Each cable wire is individually protected by an electronic component with a 100A (8/20uS) discharge impulse. In combination with uniform PCB tracks of very high thickness gives a product stable surge protection properties.

Low reflections, low foreign crosstalk, and damping for 4 x 125Mhz frequency as well as continuity of the shield connection, allowed to qualify the PTU-64-EXT module for products compliant with the 6th category cabling. This is important for large 1000Base-T LAN networks . Despite the fact that 6th category quality parameters are not used in the most popular 1000Base-T networks, the quality reserve of parameters is important for the stability of their operation, because the number of disturbing signals increases in proportion to the number of LAN cables in the Rack cabinet.

Independent PoE protection circuits eliminate the overvoltages between 1.2 - 3.6 and 4.5 - 7.8  pairs in the LAN cable. This solution protects power supplies of LAN equipment against damage due to lightning surges or uncontrolled voltage increase, for example as a result of damage to the PoE power supply. The solutions used are compatible with each PoE standard, including Hi PoE.

On the protected side (DEVICE) RJ-45 sockets are used, which allow easy crossing of LAN ports by patchcords. Unprotected side use LSA connectors (formerly Krone) and creates two devices in one: Effective surge protection system + Patch Panel designed for direct connection of LAN cables. The metal clamps are used with the FTP cable screen and you can fix it mechanically to protect it from being pulled out.

The PTU-64-ECO/PoE module is installed in a dedicated PTU/PTF-6-RACK base - up to four modules of different types. There are also ready to use 8-channel and 16-channel protection systems with all modules of the same type.
