About the DLS 350 Dual LED Light Source 850nm 1300nm

Handheld Dual LED Light Source

Compact device utilising a DLS 350 dual LED source for accurate measurements.

Product Description

The DLS 350 dual LED source allows stabilized power levels for accurate loss measurements on multi mode systems. Technicians can utilize each of the wavelengths included in this light source to reference and test with RP 4XX series optical power meters and gather measurements to meet international standards.

The DLS 350 provides a 2 kHz tone output which is recognized by the RP 4XX series power meters; the incoming 2 kHz signal is identified and an audible alert is provided by the power meter. This 2kHz signal will also allow fiber identification when used with non-invasive fiber identifier devices, such as the LFI 110.

The dual LED source comes with a female SC adapter to allow connection to test jumpers and fiber under test. Easy removal of the adapter means that the light source ferrule can be cleaned to prevent contamination of test jumpers. Additional adapters are available.
