Light Source

lightHandheld Light Source optical light source

is one of the latest self developed test instrument.It can provide 1 to 4 wavelength output according to the specific requirements including the 650nm red source,1310/1550nm wavelength for the single mode fiber and 850/1300nm wavelength for the multimode fiber or other wavelengths according to customer needs. Together with optical power meter, it acts as a perfect solution for the fiber optic network work.



  • Providing 1~4 wavelengths output and wavelengths can be optional

according to customers’ needs

  • CW, 2Hz modulation output at 650nm, and CW, 270Hz,1KHz,2KHz

modulation output at other wavelengths.

  • High stability of the output power
  • Stable output wavelength
  • Compact size and decent appearance
  • Large LCD, easy operation



  • Telecommunication networks
  • CATV networks
  • Cabling systems engineering
  • Research and education
