KI 7419 eLED Light Source

The KI 7419 is a true optically stabilised 1310 / 1550 nm LED source for high precision testing of single mode fiber. If used with an Kingfisher InGaAs power meter,  and a suitable reference lead, we have proven that loss testing repeatability of the order of 0.01 dB can be readily achieved. This level of accuracy is required when, for example, acceptance testing PC and APC optical connectors with an average loss of around 0.1 dB. Also suitable for chromatic dispersion measurement applications.
