900D Optical Fiber Tester OTDR Optical Time Domain Reflectometer 800NM-1700NM 500M-60KM With OPM VFL

Features:
- 9 functions: OTDR, event mapping, optical power meter, LED light, stable light source, network cable sequence test, VLF red light source, RJ45 line tracking, network cable length test
- Universal FC/SC interfaces: Can be replaced with different connectors. Simple and clear to operate (with SC and FC connectors, no need to purchase separately)
- 3M short blind zone, 500M~60KM test distance
- Four types of events: Reflective event, non-reflective event, fiber splitter, fiber end (Attention: please not perform live fiber test for this function)
- OPM high-precision optical power meter can identify and measure the frequency of 4 kinds of frequency optical signals. Frequencies are 270Hz, 330Hz, 1KHz, and 2KHz
- Wavelength range is 800nm-1700nm. Power range -50 to +26dBm

Details of Functions:
- VFL visual fault locator
- Stable laser light source with five working modes: CW, 270Hz, 330Hz, 1KHz, and 2KHz
- RJ45 pairing function. Hidden design RJ45 remote
- RJ45 wire track/length measurement: After the wire tracking function is activated, it is used to hunt the remote cable under test. When you hear a continuous DiDiDiDi sound, it is the cable being searched
- LED light for illumination at night
- Internal 4000ma lithium battery, ordinary USB interface
