16-channel surge protection for LAN Gigabit Ethernet, PTF-616R-EXT / PoE

16-channel surge protection for Gigabit Ethernet networks, based on structured cabling category 5, 5e, 6, and 6a. It is built from four PTF-64-EXT modules, mounted to the PTU/PTF-6-RACK base. It is installed in a 19" Rack cabinet on the front rail, allowing easy switching of cables in user networks or on the rear rail using LK-MOUNT angled brackets, in case of application for IP-CCTV recorders.

The front RJ-45 (DEVICE) sockets represent the surge-protected side, to which LAN switch ports are connected. The sockets located at the back represent the unprotected side (LINE), to which long lines of LAN infrastructure are connected. When using the PTF series protection, an additional patch panel with RJ-45 sockets is usually used. To ensure continuity of shielding for FTP cables, shielded patch cords should be used. The placement of the unprotected side sockets at the back of the protection is conditioned by the need to ensure high quality of its transmission parameters and low crosstalk.

The PTF-64 series modules are high-quality surge protection and transmission devices. The use of multilayer PCB boards and modern components in MOSFET technology has resulted in compliance with the category 6 cabling standard and correct tests for frequencies of 4 x 250MHz.

The components used in MOSFET technology significantly reduce the level of voltage protection (Up) to a value slightly higher than the nominal operating voltage (Un). The voltage pulse reaching the protected device during a surge or discharge is even several times lower than in the case of a standard solution without the use of MOSFET technology. In the event of a surge, the risk of breakdown of the insulation of isolating transformers of the physical layer is also reduced due to potential differences between locally grounded or locally powered LAN devices.

Independent PoE protection protects against voltage spikes between pairs 1,2 - 3,6 and 4,5 - 7,8. This protects the power supplies of LAN end devices from damage due to surges caused by lightning strikes or uncontrolled voltage increases, for example, due to a failure of the PoE power supply. The solutions used protect all types of PoE power and allow power transmission in the Hi PoE standard.

Proper grounding of the surge protection should be ensured by connecting the included grounding wire to a properly grounded Rack cabinet. The optional PTU/PTF-5/6-COVER provides protection for the circuits and connections of the protection against dust, and also serves as an additional shield against interference when a large number of panels are used.

The best level of protection is achieved by using surge protectors on both sides of the cables: Multi-channel on the LAN switch side and single on the end device side, for example, PTF-61-EXT/PoE.

The product is tested according to categories D1, C2, C1, B2. It is intended for use at the boundaries of LPZ0/LPZ1 zones or higher.
