Set-Up: Full Auto Mode Settings Definitions Core Settings Full Auto Mode settings are common for all OTDR Test Modes and will be referred to as Core Settings. Launch Cable (Launch Cord) A test cable used to connect the OTDR to the near end of the link under test that is long enough to allow the OTDR to measure the loss of the first connection.
Set-Up: Live Mode Settings In addition to Core Settings, the Live mode allows you to set the Wavelength and Range parameters. Choose a wavelength for your test port selected Press the Left / Right arrow key to display the desired value Set-up: Expert Mode Settings In addition to Core Settings (Full Auto Mode settings), the Expert test mode allows you to set the Wavelength, Range, Pulse Width, Averaging Time, Filter parameters.
Set-up: Expert - Manual Setup Note: The Range, Pulse Width, and Averaging Time parameters are user-selectable if the [Setup] parameter is set to [Manual]. Range The [Range] parameter determines the distance range of the full (unzoomed) trace. It also determines [Resolution] - the distance between data points in the trace: the longer the range, the wider the data point spacing. We recommend selecting the shortest distance range that is longer than the fiber under test.
File Manager File Manager is accessed from the File tab > [Folder...] parameter in Main Menu settings, or from the Home page by using the [Files] soft key. Use to change folders and go between CF, USB, and Internal storage. Use Tools within the File Manager to create, delete, copy and move files and folders.

Transferring Files From M200 via USB Function port to PC To transfer files from your M200 to a PC using a USB cable, perform the following: 1 Connect your M200 to a PC using a type A to Mini USB B cable. If your PC requests new USB drivers, install the CD-ROM that comes with your M200, which should contain the needed drivers. This step only needs to be performed the first time you connect your M200 and PC together.

Recommended Accessories You will need fiber optic test jumpers to connect your M200 to the fiber under test. Test jumpers must have the same core and cladding size as the fiber under test. The connector at one end of the test cable must mate with the appropriate optical port on the M200. The connector on the other end must mate with the fiber optic link under test.
Cleaning Tips Clean Test Cables and FUT Connector end faces must be kept free from dirt or other contaminates to ensure accurate measurements and operation. It is important to keep connectors on the launch and receive cables and those on the Fiber Under Test (FUT) clean. Follow your company’s approved cleaning procedures. Cleaning the Optical Ports CAUTION! Before conducting the following procedures be sure to have the M200 turned OFF.
FAQs Can I save traces for viewing later? Yes. There is a dedicated Save key. In the Main Menu “File Tab”, set up the location/ folder (Internal, CF, or USB) to save the file, the file naming format and fiber number. The fiber number will increment after each trace is saved. Tips Expert OTDR Setup RANGE: Length • Too Short: you will not capture the entire fiber length • Too Long: trace will be squashed to left side of Screen • Good Range: 1.
Recharging Batteries Repair and Calibration You may charge the batteries while the M200 is switched on or off by attaching an AC power adapter. Unauthorized repair of the Noyes test equipment will void the warranty. • Plug the AC adapter/charger into a standard wall outlet. • Connect the AC adapter/charger to the Power port located on the M200 side panel. • The [AC/Charger] indicator on the side panel will turn on- Red • Charge batteries until the [AC/Charger] indicator turns Green.
