DLS 650

Dual Multimode LED Source

  • 850nm and 1300nm wavelengths
  • Automated Wave-ID mode compatible with RP 560 power meter
  • 2kHz, 1kHz, and 270Hz tone modulation

Product Description

The DLS 650 optical LED source provides multiple wavelength options to meet modern fiber optic testing needs. The base model outputs 850 and 1300nm wavelengths in either single or dual mode.

When combined with the RP 560 model optical power meter, this LED source can greatly reduce the time needed to test fiber cables with its automated wavelength switching feature. The unit periodically switches between available wavelengths, and the power meter recognizes each time the switch occurs, allowing multiple loss tests to be completed simultaneously.

Easy removal of the included SC adapter allows the light source ferrule to be cleaned, preventing contamination of test jumpers. Additional adapters are available.

This device maintains full compliance with all FDA and CFR standards for light-emitting products.
