Instrument sa 4 metode mjerenja:
- OTDR mjerenje i ispitivanje trase
- OPM mjerenje nivoa aktivnog signala (optical power meter)
- Izvor aktivnog signala (signal source) za OPM mjerenje
- Laser za svjetlosnu VFL detekciju vlakna
The OTDR NK2800 mini optical time domain reflectometer is compact and easy to carry; itadopts a 3.5-inch high-definition touch screen, supports multi-touch and smooth operation.Internal integration of OTDR, event map, optical power, red light, flashlight and othe rfunctions in one, to meet various test needs in diferent occasions. Among them, the OTDRfunction adopts 1550nm wavelength and built-in high-efficiency wavelength isolator. lt can perform optical test on 1490nm and 1577nm links. lt supports up to about +10dBm with optical test capability, and the maximum measurement range is 80km.
The SFT2800 is used to measure the length, loss, connection quality and other parametersof the optical fiber. lt can easily test the breakpoint, bend, and loss point of the optical fiber link. lt is suitable for line maintenance and emergency repair testing by installation and main-tenance personnel.
