dBm Optics 2004 Passive CSA

The dBm Optics 2004 Component Spectrum Analyzer™ will characterize loss, polarization dependencyand return loss quickly, accurately and repeatable—all at an affordable cost. dBm Optics’ technology supports unprecedented optical repeatability, accuracy, and speed. A device can be characterized over a 100 nm spanat 1 pm resolution with 1 pm and 0.015 dB accuracy in less than 1 second.

Loss measurements usually require a reference measurement—then a measurement of the loss. The 2004 eliminates the need for the reference measurement entirely by using a proprietary real-time reference. The 2004 is constantly monitoringthe input power to the device and calculating the lossbased on the power out of the device. In addition to speeding the measurement and eliminating the reference errors, the 2004 also eliminates the effect of variation in the source power between the reference and the loss measurement. The result: the most accurate loss measurements available anywhere.
