Feature:1. HIGH PERFORMANCE CHIP: This optical time domain reflectometer is with high performance chip and can do stable running and accurate measuring.2. 4.3INCH CAPACITIVE SCREEN: OTDR tester is with 4.3inch multi touch capacitive screen with new gesturing amplification and screen capturing. 12 in 1 multifunctional.3. LINE ORDER REMOTE ADAPTER: The OTDR tester is with concealed net cable line order remote adapter and can do net cable pairing, net cable sourcing, wire ranging.4. AUTO OR PROFESSIONAL OTDR: This tester is versatile and with auto OTDR, professional OTDR event map, light power meter, visible red light, adjusting light source, optical loss test, net cable pairing, net cable sourcing, wire ranging.5. HIGH ISOLATION BILATERAL: OTDR tester is with high isolation bilateral, filtering technology with light testing, support less than 5dBM optical signal with light testing, even with light testing will not be leading to optical device damage, strict protection of their own parts, to deal with more complex testing environment.Specification:Item Type: Mini Optical Time Domain ReflectometerMaterial: ABSBattery: Built In 3.7V 4000mah Polymers Lithium Battery (Reflectometer Shipped With Built-In Battery) 1.5V AAA Battery x 2 (Receiver Shipped Without Battery)Uses: Used To Evaluate FTTx And Access Net Construction And Maintenance, Identify Fiber Breakpoints, Measure The Length Of Optical Cable, Calculate The Relative Optical Power LossBasic Parameters:Test Wavelength: 1550nmWith Light Test: Not SupportedFiber Type: G.652 Single Mode FiberDynamic Range: 24dBEvent Blind Area: 2.5mAttenuation Blind Area: 8mMeasurement Range: 500m, 1km, 2km, 4km, 8km, 16km, 32km, 64km, 100kmPulse Width: 3ns-20usDistance Measurement Accuracy: (1m Plus Sampling Interval Plus 0.005% x Test Distance)Linearity: 0.05dB/DBSampling Points: 16k To 128kSampling Resolution: 0.05m To 8mReflection Accuracy: 3dBWavelength Range: 800nm To 1700nmOptical Connector: Universal Connector FC SC STMeasurement Range: -70dBm To +6dBm Or -50dBm To +26dBmUncertainty: 5%Frequency Identification: CW, 270, 330, 1k, 2kHzCalibration Wavelength: 850, 980, 1300, 1310, 1490, 1550, 1625, 1650nmLaser Type: FP LDOutput Wavelength: 1550nm20nmOutput Power Adjusting: (-2dBm To -10dBm) 2dBModulation Frequency: 270, 330, 1k, 2kHzStability: CW, 0.2dB/15min (Tested After 15min Power-On Warm-Up)Optical Connector: FC Or UPC (Interchangeable SC, ST)Working Wavelength: 650nm20nmOutput Power: 10mWOperating Mode: CW, 1Hz, 2HzOptical Connector: Universal Connector FC, SC, STTesting Distance: 0 To 300m.Package List:1 x Reflectometer1 x Instruction Manual1 x Charging Cable1 x SC Adapter1 x Rj45 Receiver1 x Storage Bag1 x StrapNote:1. Connector Cleaning.The optical output connector is a replaceable universal connector, and the end face must be kept clean during use. When the instrument fails to test the normal curve, or the test result is inaccurate, first consider cleaning the connector.When cleaning, be sure to do so with both the OTDR and visual red light fault location functions turned off. Unscrew the output connector and wipe the connection surface with a special dust free paper towel or cotton swab moistened with alcohol. At the same time, please put the dust cover on after the instrument is used, and must also keep the dust clean.2. Screen Cleaning.The display of the optical time domain reflectometer is a 4.3inch TFT full view color LCD with capacitive touch screen, do not use incisive objects to click on the LCD screen, otherwise it may leading to damage to the LCD screen, when cleaning, use a soft paper wipe to clean the LCD screen. Do not use organic solvents to wipe the LCD, otherwise it may leading to damage to the LCD.
