BN 2331/12 Fig. 1 OCC-4056C module The OCC-4056C is VIAVI’s new generation of DWDM analyzer modules. It scans the full C-band wavelength range between 1528 and 1568 nm for commissioning, upgrade, and trouble shooting of DWDM networks. The OCC-4056C offers the functionality and speed of an optical spectrum analyzer in a handheld form at a fraction of the price of an OSA.
Chapter 1 Optical Spectrum Measurement Safety information SFP slots The OCC-4056C offers 2 integrated SFP slots for mounting up to 2 SFP transceiver modules or tunable lasers (to be ordered separately). These SFP+ modules can be used as a DWDM stimulus to check DWDM networks together with the DWDM analyzer.

Chapter 1 Optical Spectrum Measurement Acquisition Acquisition To start a measurement press the key. TART The OCC-4056C will scan over the entire wavelength range and the measurement result will be displayed in graphical and tabular format. Trace display By pressing the button the results window is displayed.
