PoE Power-on-demand products


















Our PoE power-on-demand midspans support 10/100/1000 (gigabit) Ethernet, are designed around an open silicon platform, feature USB connectivity for the management console, and are designed and tested in the USA for greater focus on the North American PoE market.
Midspan ports with ethernet cables


Power-on-demand midspans allow your best-in-class network switch to handle the data without limiting your available power. This advanced midspan technology provides full-power on every port and is a more cost-effective solution to expand your network capability because it isolates the data to the switch and the power to the midspan. Today’s midspans can deliver the necessary power to current and future generations of VoIP phones, wireless LAN access points, remote IP security cameras, access control devices, RFID readers, motion detectors, keypads, building automation controls and other emerging products.

15.4W/port, IEEE802.3af - Power-on-demand Midspans
The current IEEE802.3af standard for Power-over-Ethernet, was formally approved in 2003, defining PoE applications requiring up to 12.95W of power. With this specification, users were no longer locked into one brand of equipment and experienced fewer equipment problems and hazardous situations caused by non-compliant products. The standard facilitates interoperability, ensures power application only where appropriate, and mandates safety precautions and protection against faults in an installation.

30W/port, IEEE802.3at - Power-on-demand Midspans
With the expansion of PoE applications, the need for higher power has also grown. IEEE organized a task force, of which Phihong is a member, to evaluate these needs and define a new standard. IEEE802.3at standard, (PoE Plus) presently allows for 30W/port of power. Ratified in September 2009, Phihong has already developed many products that are already compliant to the new IEEE802.3at standard and deliver high-power PoE, benefiting applications such as wireless multi-radio access points, Pan Tilt Zoom security cameras, and IP phones with streaming video displays.

60W-80W/port - Power-on-demand Midspans
Even before the PoE Plus standard was approved in 2009, users were demanding applications that require more than 30W of power per port, such as computer workstations, LCD display panels, and WAP arrays, Other emerging applications, including emergency lighting security system sensors, and even medical monitoring, will greatly benefit from combining data and centralized backup power. Phihong’s Ultra PoE products can deliver from 60W to 80W per port with the same protection and safety precautions as standard PoE.

95W/port - Mega PoE Midspans
Even before the PoE Plus standard was approved in 2009, users were demanding applications that require more than 30W of power per port, such as computer workstations, LCD display panels, and WAP arrays, Other emerging applications, including emergency lighting security system sensors, and even medical monitoring, will greatly benefit from combining data and centralized backup power. Phihong’s Ultra PoE products can deliver from 60W to 80W per port with the same protection and safety precautions as standard PoE.

Extenders and Accessories
Extend your network beyond 100 meters. According to the IEEE, data transfer beyond 100 meters is neither standard nor recommended as it will lead to data disintegration, but Phihong has developed a series of extenders capable of expanding a PoE network’s reach that complies with the IEEE standard and does not require having to move the midspan’s communication cabinet. Users may now power equipment up to 200 meters (over 650feet) away from a network switch making it ideal for large facilities including auditoriums, sports arenas and warehouses.
