FHO1000 Handheld OTDR Optical Time Domain Reflectometer with VFL OLS OPM RJ45 Sequence 1310/1550nm 28/26dB


SKU: N/A Category:

FHO1000 Handheld OTDR is the latest smart OTDR of Grandway. Although it is a handheld OTDR, it can measure the length of optical fiber over 100km. In short distance optical fiber testing, with the excellent 1m/4m deadzone performance, all kinds of continuous connectors, attenuation loss and other events can be clearly distinguished. FHO1000 is equipped with 1310nm and 1550nm dual wavelength OTDR, optical power meter, stable laser source, 10mw VFL, RJ45 line sequence measurement and other functions. At the same time, it has bluetooth wireless connection and supports pairing with mobile phones.


  1. 5 inch color LCD, portable design and easy to carry.
  2. Multi function integration, support 10mw VFL, stable laser source, optical power meter, RJ45 line sequence test and other functions.
  3. High precision, short deadzone OTDR can accurately test all kinds of continuous connectors and attenuation points in the line.
  4. 28dB dynamic support over 100km optical fiber measurement.
  5. Simple mode and expert mode are convenient for application in different scenarios.
  6. Bluetooth connection of mobile phone supports fast transmission of test files to mobile phone.
  7. Mobile phone remote control, control OTDR test and curve view analysis through the mobile phone app.
  8. Support remote online upgrade
