The was specifically designed for applications where for measuring, monitoring and logging of insertion loss or power fluctuations are needed. The OP510 is a small (4"x2"x1.25") module designed such that minimal movement and bending of the reference- and test cables is necessary. This results in stable, accurate and repeatable measurements.

A unique feature of the OP510 is the that displays the user the approximate power absolute or relative power level. The button on the module allows the user to the reference function or to trigger a computer based measurement. The OP510 is offered with various detectors with the commonly used or fixed optical interfaces. These options cover wide variety of applications.
