                   Detailed Product Description 
                   Optical Light Source (NF-902) 
  
Summarize 
Handheld Light Source optical light source is one of the latest self developed test instrument. It can provide 1310/1550nm wavelength for the single mode fiber.  Together with optical power meter, it acts as a perfect solution for the fiber optic network work.  
  
Product features 
◆ Providing 1~4 wavelengths output and wavelengths can be optional according to  
    customers needs 
◆ CW, 0HZ modulation output at 650nm , and CW, 270Hz, 1KHz,2KHz modulation output at    
    other wavelengths 
◆ High stability of the output power 
◆ FC/PC or other type connectors can be required 
◆ Compact size and decent appearance 
◆ Large LCD, easy operation 
  
Main applications 
 
◆ Measurement of the power of optical sender (dBm and W) 
◆ Loss test of optical fiber link 
◆ Insertion loss test of optical device 
◆ Installation and maintenance of fiber fibre link
