MAY131 Optical Light Source 1310/1490/1550nm with FC and SC Adapters and Lithium Battery, and Automatic Wavelength Recognition


SKU: N/A Category:

MAY131 Series Optical Light Source adopts novel and ergonomic desgin, which is durable. The ports of Optical Power Meter and Visual Fault Locator adopts embedded detector, which can be well protected.

It supports SM/MM light source output, wave ID and TWINS mode output. The output power is adjustable.


  • Output power is adjustable
  • Support modulated light
  • Support wavelength ID
  • Support 0.1dB/1dB step
  • Automatic wavelength recognition(TWINS mode output)

MAY131 Series Optical Light Source can transmit with a wavelength identification digital encrypted protocol, enabling MAY130 Series Optical Power Meter to automatically switch to the proper calibration wavelength. This feature reduces the need for communication between two technicians and decreases the possibility of making mistakes.
