GL-808GP-2G2SFP

What is the history of POE international standards?

IEEE began to develop the standard in 1999, and the earliest participating vendors were 3Com, Intel, PowerDsine, Nortel, Mitel and National Semiconductor. However, the shortcomings 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 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. The IEEE 802.3at standard was formulated in 2005 and promulgated in 2009. The output power of the 802.3at standard can reach 30W, and the available power at the receiving end is 25.5W. The IEEE 802.3 working group and the alliance of various manufacturers launched POH-POWER OVER HDBASET in the industry at the end of 2012.

Poe Switch, also named as Poe Switch Ethernet, is one of the Switch that have Poe Port that can do Poe Power Supply.

To fulfill the demand of High Power PoE for network applications with Gigabit transmission, GL-COM GL-808GP-2G1SFP PoE Gigabit Ethernet Switch is an ideal solution. Each 10/100/1000Mbps port of the GL-808GP-2G1SFP features IEEE 802.3af and IEEE 802.3at Power Over Ethernet (PoE) that combine up to 96/120-watt PoE budget on the whole system, It is designed specifically to satisfy the growing demand of higher power consuming network PD (powered devices) such as PTZ (Pan, Tilt & Zoom) / speed dome network cameras, multi-channel (802.11a/b/g/n) wireless LAN access points and other network devices by doubling Poe Power , more than the current conventional 802.3af PoE.

All RJ45 copper interfaces of the GL-808GP-2G1SFP support 10/100/1000Mbps auto-negotiation for optimal speed detection through RJ45 Category 6, 5 or 5e cables. It also supports standard auto-MDI/MDI-X that can detect the type of connection to any Ethernet device without requiring special straight or crossover cables. 2 extra 10/100/100Mbps RJ45 and 2 extra 1.25Gbps SFP slots can be used for uplink.
