www.level1.comDespite of the power required by the PoE Repeater and the power loss from the cable, the further the distance from the PSE, then the greater the powerdrops off.The diagram shows a standard PoE Power Sourcing Equipment which supplies 15.4W of power. It can be seen that when repeated twice, there is moredrop off in the end power available for the PoE device.100m100mPowerStandard 15.4WPoE PSEPOR-0100PoE Device (≤10.9W)100m 100m 100mPowerStandard 15.4WPoE PSEPOR-1100POR-1100PoE Device (≤6.5W)This table shows the estimated power available at different distances when the PSE is a Standard 15.4W source.Connect with Standard 15.4W PSEEnd to End Distance 100m 200m 300m 400m 500mDaisy-Chaining 0 1 2 3 N/A( 1-Port PoE Repeater)Power Available 12.9W 10.9W 6.5W 3.84W Data onlyNo powerTo overcome the power loss, we can extend the distance possibly by increasing the power input at the PSE.LevelOne has a range of High Power PSE for this application, such as FSW-0513 PoE switch (48W), POI-4000 PoEinjector (40W), or POI-3000 Gigabit PoE Plus Injector (30W).Connect with High-Power 30W PSE, POI-3000 / 40W PSE, POI-4000 (refer to page 8)End to End Distance Daisy-Chaining Power Available( 1-Port PoE Repeater) 30W PSE (POI-3000) 40W PSE (POI-4000)100m 0 - -200m 1 25.5W 28W300m 2 21W 25.5W400m 3 16.5W 21W500m 4 12W 16.5W600m 5 7.5W 12W700m 6 3.84W 7.5W800m 7 Data only No Power 3.84W900m 8 - Data only No PowerPPM-1000PoE Power Measurer- Ensure your PoE device workscorrectly- Measure available power (watts)and voltage in a PoE line- Portable and compact size- LED display and indicators toreveal the power status- Built-in temperature sensor- Replaceable external batterypack for real portability- Detachable neck strap- Build-in temperature sensor andLED indicator to inform useroverheat condition if high powerload test is appliedDue to the length and quality of cable, it is difficult to be certain that there is enough power available to power thePoE device. So for the convenience of installers, LevelOne has a compact and portable PoE Power Measurementdevice to examine and test the power status in real time. In essence, it guarantees that sufficient power will besuccessfully delivered to the PoE device.22
