    Handheld Three Wavelength Source (1310/1550/1625)

    Model TLS
    Price:   US$1,180.00

This model of three wavelength light source integrates three useful laser sources into one single handheld test instrument, catering to more convenient application demands for optical fiber network construction and maintenances. It provides light source at 1310, 1550, and 1625nm for single-mode fiber measurement. FP laser diodes are used, and the output power is no less than 0dBm for each wavelength. This instrument is especially useful in testing optical link with C and L band transmission, or WDM optical fiber networks that uses 1625nm as monitoring channel.



  • Locating fiber breaks, micro-bends even through jacketed fibers
  • End-to-end fiber identification
  • Stabilized output power (0dBm)
  • High reliability


  • Telecommunication networks
  • CATV networks
  • Cabling systems engineering
  • Research and educational usage

Standard Packages:

  • Laser source module
  • User manual
  • Protective holster
  • 8.4V Ni-Cd rechargeable battery


Three types of adapter accessories provided.
