The technique of Dense Wavelength Division Multiplexing is well established and adopted worldwide as a means of increasing the traffic carrying capacity of a fiber. Optical cross connects, wavelength routing and translation, now make a typical network far more complex in construction. Identification of an individual channel and verification of the data passing over it during installation, commissioning and routine maintenance as part of a Service Level Agreement (SLA) is becoming more critical. The MN9320A Optical Channel Drop Unit is a test instrument that scans the DWDM optical signal and displays all those channels present in the form of a bar graph. Any individual channel can be selected from this display and fed to its output port which can then be connected to a protocol analyzer such as the Anritsu MP1570A for data validation and testing. Wherever the integrity of a DWDM signal must be verified, the MN9320A can be used.
Independent DWDM signal access for channels of 50 GHz spacing or higher up to data rates of 10 Gbps.
