KI 3840 VCSEL Source

The inexpensive KI 3840 handheld VCSEL laser source is a specialised source for testing multimode systems at 850 nm. Compared to a LED source, a VCSEL source may provide a better modal match to the operating conditions of a data system. However, all VCSEL sources give very poor measurement stability, and so should only be used if required. Measurement is usually possible to only about 0.1 dB resolution, so they may be suitable for measuring end to end system loss, but are probably unsuitable for measuring connector loss.
