Optical Matrix: Measuring Methods & Facts Bidirectional Measurement without Disconnecting
Each Test Point can individually act as: Sender, Receiver, Monitor Receiver and Receiver for Reflection Measurement
Insertion Loss and Return Loss can be measured separately
Mixed Configuration is possible (Wavelength, Fiber, Launching Methods, etc.)
Measurement Time between 200ms and 500ms depending on specified repeatability
Optical Output Connector: FC
