PoE Classification (I)

IEEE 802.3af – Max Power : 15.4W Max Current : 350mA PSE Voltage : 44~57V PD Voltage : 37~57V Mode A : Power by Pair (1,2) & (3,6) Mode B : Power by Pair (4,5) & (7,8) DC Polarity : Any Cable : CAT3 or CAT5 Data Rate : 10/100/1000Mbps IEEE 802.3at – Max Power : 25.5W per Mode Max Current : 600mA per Mode (Note) PSE Voltage : 44~57V PD Voltage : 37~57V Mode A : Power by Pair (1,2) & (3,6) Mode B : Power by Pair (4,5) & (7,8) Mode A + B (Note) DC Polarity : Any Cable : CAT5 or CAT6 Data Rate : 10/100/1000Mbps Note : Incorporate into 802.3-2012

PoE Classification (II)

Passive PoE(Non-Standard) – Max Power : By Manufacturer Max Current : By Manufacturer Voltage : 12/24/48 Typical Mode : (4,5) & (7,8) Typical DC Polarity : Any Cable : CAT5 or CAT6 Data Rate : 10/100Mbps Typical There is no negotiation between PSE and PD for power requirement. Cisco UPoE – Max Power : 60W Max Current : 1A PSE Voltage : 44~57V PD Voltage : 37~57V Mode : Power by All 4 Pair DC Polarity : Any Cable : CAT5 or CAT6 Data Rate : 10/100/1000Mbps

Difficulties of PoE SPD Design

 Generally, 30V transient voltage could damage Ethernet IC  PoE IC can only sustain 100V transient voltage  Gigabit Ethernet requires low capacitance load on data line (<10pF)  There are types of devices operated in different PoE mode  Actually, PSE and PD has different circuit, and requires different design  SPD must have high surge capability and reliability

How To Evaluate PoE SPD

 Does it compatible with IEEE 802.3af & 802.3at standard?  Does it compatible with non-standard PoE devices?  What’s the performance when apply on real PoE devices?  If its surge capability is real?  Is it small enough for your installation?  Will your devices be damaged before SPD failure?

Conclusion

 PD1000MG can reach 1KA discharge current per line, that means total 8KA for

line to earth protection.(Refer to IEC61643-21)

 It won’t affect transmission of Gigabit PoE, even apply on 100M CAT5e cable.  Protection capability was demonstrated by real application, PD1000MG does

protect devices from damage.

 Built-in failure indicator makes it easy to maintain.  Size only 25mm x 40mm x 80mm  We assumed that PD1000MG is the best Gigabit PoE surge protector in the

market right now.
