JW3306E Optical Fiber Identifier is an important tool for optical maintenance, which is used for nondestructive fiber identification project. Meanwhile it also has visual fault locator module with fault location function. Using the macro bending technology on line for nondestructive testing, JW3306E can measure the signal direction and power and avoid misoperation resulting in interrupted lines.Features*TFT color screen* Indicate the signal directions and power in fiber* Indicate the signal presence or absence(Live or dark fiber)* Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning* Displays the relative core power* Don't need to replace adaptor. Adapter can be used for 250um, 900um, 2mm and 3mm cables.* Lower power indication* Build in VFL function* Build in OPM functionSpecificationsModel JW3306EIdentified Wavelength Range 750-1700 nmInsertion Loss 1.0dBFiber Type ＜ 3mm FiberIdentified Signal Type 270Hz/1KHz/2KHzDisplay Type LEDDetector Type 1mm InGaAsMinimum detection power -35dBm(1550nm) -30dBm(1310nm)OPM ModuleWavelength Range（nm）1800~1600Detector Type InGaAsMeasurement Range（dBm）-50~+26Photosurface 300umUncertainty ±0.15dBAccuracy Linear 0.1% or Nonlinear 0.01dBmVFL ModuleCenter Wavelength 650nmOutput Power 10mWAlkaline Battery 2*AABattery Life ＞ 60HOperating Temperature 0~+50℃Storage Temperature -20~+60℃Weight 200gStandard PackageJW3306E optical fiber identifier, carrying bag and user manual
