Description GreenTel GPN80 series PON Power meter is developed for a quick,Website:http://www.greentelfttx.com, on-site testing of all PON signals, anywhere on the network. It is capable to measure the concurrent upstream/downstream data via a pass-through connection, with simulating software management capabilities and enhanced ruggedness, it increases the efficiency of technician’s daily deployment activities.Moreover, its visual fault locator port allows for easy fiber identification and macro-bend location.This handhold unit also features pass/fail indications with use-defined thresholds.Features ● Automated pass/fail assessment● Quick and efficient visual inspection● Providing distinct power values for 1310 nm, 1490 nm and 1550 nm● Pass through measurement● Simultaneously measure and display the concurrent voice,data and video signals on different PON architectures● Manual calibration● One-year warranty and three-year recommended calibration intervalSpecification PON Power Meter - GPN80 Parameter ModelGPN80Measurement Range(dBm)1310 nm: +10 ~ - 35 dBm/1490 n m: +10 ~ - 50 dBm/1550 nm: +25 ~ - 45 dBmPass Through Loss< 1.5 dBAccuracy *+/- 0.2 dB (burst signal: < 0.5dB)Threshold sets10Data Storage100ConnectorSC/UPC ( or customize )Auto Power OffNo operation in 10 minutes (can be canceled), Low battery energyBattery ChargeYesConnect To PCOptional functionManual CalibrationYesOperate TimeAbove 36 hoursPower Supply3* AA batteries or AC/DC power supply adapterSize(H*W*D)190mm  x  90mm  x  40mmWeightAbout 450gStorage Temperature-20  to  +60℃ ,<90% RHOperating Temperature-10  to  +50℃ ,<90% RH* at 20.3 degrees, with SC/PC connector, -10dBmStandard Package①GPN80 main body*1②Nylon bag and the Q/C certificate*1③Operation Manual*1④Paper BoxOrdering InformationGPN80-X-XX-XXX(X:1)  N=PPM   2) T = PPM+PM(-70 ~ +6dBm)   3) C= PPM+PM(-50 ~ +26dBm)(XX:1) V00 = Without VFL   2) V01 = 1mw VFL   3) V10 = 10mw VFL(XXX1) N = Without USB interface    2) U = With USB interface
