EXFO Inc. (Canada) introduces the new FTB-5230S-OCA Optical Spectrum and Optical Channel Analyzer module, which adds the test capabilities of an inexpensive and efficient channel analyzer to the traditional optical spectrum analyzer functions (power and center wavelength measurements), including measurements of high power levels up to +23 dBm. It is a powerful, yet easy-to-use, intuitive instrument that can be upgraded from a simple channel analyzer to a full-fledged spectrum analyzer by simply installing a software key.
