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
