What is Power over Ethernet (PoE)?
PoE (Power Over Ethernet) refers to the use of IP-based terminals (such as IP phones, wireless LAN access points AP, network cameras) without any changes to the existing Ethernet Cat.5 cabling infrastructure. Etc.) While transmitting data signals, it can also provide DC power supply technology for such devices. PoE technology supports the normal operation of the existing network while maintaining the safety of the structured cabling, helping to minimize costs.
Power over Ethernet connection
PoE is also known as a local area network-based power supply system (PoL, Power over LAN) or Active Ethernet (Active Ethernet), sometimes also referred to as Power over Ethernet for short.
PoE technology uses existing standard Ethernet cables to transmit both data and electrical power simultaneously, in line with the latest standards. It also maintains full compatibility with current Ethernet systems and users.
International PoE Standard
IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the limitations of this standard have been restricting the expansion of the market.
Until June 2003, the IEEE approved the 802.3af standard, which clearly stipulates the power detection and control items in the remote system, and connects routers, switches, and hubs to IP phones, security systems, and wireless LANs through Ethernet cables.
The IEEE 802.3af standard is a new specification developed for Power over Ethernet (PoE) systems, extending the IEEE 802.3 framework to support direct power delivery over Ethernet cables, and it is the first international standard for power distribution. The method of power supply for points and other equipment is regulated.
The development of IEEE 802.3af includes the efforts of many company experts, which also allows the standard to be tested in all aspects.
THOR Surge Protective Device for Gigabit Ethernet PoE:
Data Surge Protective Device SPD TRSS-RJ45 Series for PoE and Signal Surge Protection
Basic circuit diagram
THOR Gigabit Ethernet PoE SPD/Lightning Arrester (also known as Data Line SPD and Transient Voltage Surge Suppressor or TVSS) TRSS-RJ45 series can be manufactured within 7 to 10 days of 500 pieces or more. Our Gigabit Ethernet PoE SPD/Suppressor protects your electronic equipment and supports long-term system reliability by absorbing large amounts of transient energy.
TRSS-RJ45 for data line applications helps prevent damage that may be caused by energy spikes resulting from lightning and other strong power. The TVSS/transient voltage surge suppression device for Gigabit Ethernet PoE can be used as a lightning arrester and an electrical overvoltage spike protection unit.
THOR's TRSS-RJ45 series data line surge protection devices are designed to protect Gigabit Ethernet PoE from transient voltage power spikes. These commercial - grade SPDs deliver advanced, high-performance surge suppression and are intended for indoor use. Free samples of the indoor Gigabit Ethernet PoE SPDs are avaliable and can be shipped within one week.
THOR Gigabit Ethernet PoE SPDs from the TRSS-RJ45 series features a shielded RJ45 connection for enhanced performance. It provides industrial-grade protection against lightning and transient power surges. Detailed specifications, technical drawings, and a PDF with precise dimensions of the TRSS-RJ45 series SPDs are available upon request.
The Gigabit Ethernet SPD utilizes a gas discharge tube (GDT) protection circuit to suppress transient voltage surges caused by lightning and power spikes. The GDT-based design effectively protects electronic equipment connected via data lines. Part of the TRSS-RJ45 series, the commercial Gigabit Ethernet PoE surge protection device is fully compliant with EN/IEC 61643-21 standards.
