Phihong has Midspan power solutions that address 4 different power levels:
The IEEE802.3af standard for Power-over-Ethernet, was ratified in 2003 and defines the specifications for PoE applications, such as VoIP phones and single radio access points, which can require up to 12.95W 15.4W of power per port.
The IEEE standard was expanded in 2009 to include IEEE802.3at, which is also known as PoE Plus. The IEEE802.3at standard defines the specifications for PoE applications, such as wireless multi-radio access points, Pan-Tilt-Zoom security cameras, and IP phones with streaming video displays, which can require up to 30W of power per port.
As applications for PoE connected devices continue to proliferate, Phihong has joined the IEEE task force to evaluate these needs and define a new standard referenced as IEEE802.3bt. The IEEE802.3bt standard, which is expected to be released sometime between Q1-Q2 of 2018, will define the specifications for high power PoE applications, such as multi-radio access points, computer workstations and LCD display panels, which can require up to 90W of power per port. Unlike the IEEE802.3af and IEEE802.3at standards, which only use two pairs of wire within the Ethernet cable for power, the IEEE802.3bt standard will utilize all four pairs of wire within the Ethernet cable to ensure safe and reliable power.
Phihong will continue to support its legacy Non IEEE PoE solutions, which included the following:
