  • Page 5: Introduction

    The Compact Photonic Tools are stackable, so you can assemble individual test sets. Common features The cOPM-A1 offers a new portfolio of point solutions for fiber optic test applications. The cOPM-A1 Optical Power Meter is optimized for a number of applications ranging from general lab use to test and process automation for passive optical components.

  • Page 6: Operating Manual Update

    NTRODUCTION Innovative features Auto dark current The cOPM-A1 removes the need for manual dark current measurements through innovative analogue circuit design. Typical power meters must be routinely and manually terminated to measure residual current from the photodiode. If this termination is not performed,or performed poorly, significant errors can result for low power measurements.
