LS310 Series

Light Source

The LS310 Series of light sources is perfect for qualifying applications using fiber optics for the physical layer, including FTTx, CATV, PON, and long haul networks. These user-friendly instruments project a high-precision, semiconductor-grade laser for stable and accurate measurements.
LS310 Series units work in conjunction with a Visual Fault Locator (VFL) for detecting bends, splices, and faults in optical fiber.
Use the LS310A/B in conjunction with an AE210, 230, or 270 Optical Power
Meter to access new paired functions such as wavelength auto-ID. Dual-λ mode switches between two wavelengths rapidly, producing measurement data for both.


  • Multi-wavelength output: 1310 & 1550nm, or 1310 & 1490 & 1550nm
    (depending on model)
  • CW mode or modulated mode: 270Hz, 1kHz, 2kH
  • 40 hours’ working time
  • New features: pair with AE210 Series OPM to auto-verify wavelengths
    and run dual-λ testing
