Exfo IQS-9310 Channel Selector

The EXFO IQS-9310 Channel Selector is a tunable optical filter module engineered to isolate and select individual optical channels within DWDM and CWDM systems. Operating as a dedicated component of the IQS-600 Integrated Qualification System, it enables precise wavelength characterization, amplifier performance validation, and bit-error-rate testing on specific channels in long-haul and metro optical networks. The flat-top filter design delivers low insertion loss and high channel isolation, ensuring measurement integrity across protocol and DWDM applications.
