POF Test Instruments

The FibKey 6803 power meter and 6903 light source are designed for performance testing in POF connector production and applications. A 4×4 mm large-area detector reads virtually all POF types. Interchangeable adapters fit Toslink or Versalink connectors. Runs over 500 hours on two AA batteries — ideal for long production shifts and field work.

Features:

High accuracy, excellent repeatability, stable readings
Full functions: absolute power (dBm/mW/µW/nW) and relative power (dB)
Fast response and dynamic display for connection-loss testing
Auto-ranging ensures full-scale accuracy
Set and store reference values for different wavelengths
Two-color molded housing: comfortable, compact, impact-protected
