Viavi MTS 2000 Quick Card

E4100-series OTDR SMART TEST ASSISTANT This quick card describes how to connect to a fiber under test, configure SMART TEST OTDR settings, run tests, and analyze results with a VIAVI T-BERD/MTS-2000 and 4100-series OTDR module. Equipment Requirements: • T-BERD/MTS-2000 equipped with the following: o Fiber Optics Software Release V18.50 or greater o E4100 Series OTDR Module • Fiber optic cleaning and inspection tools • Launch Cable (minimum 20-meter Fiber optic patch cable) with connectors matching the OTDR port and Fiber Under Test • Optical Coupler to connect Launch Cable to Fiber Under Test Figure 1: Equipment Requirements The following information is required to complete the test: • Type of Fiber (Multimode or Single Mode) • Type of Connectors (SC UPC, SC APC, LC UPC, etc.) • Distance unit (feet, meters, miles, kilometers) Fiber Inspection Guidelines: • Use the VIAVI P5000i or FiberChek Probe microscope to inspect both sides of every connection being used (OTDR Port, Launch Cable, bulkhead connectors, patch cords, etc.) • Focus the fiber on the screen. If dirty, clean the connector. • If it appears clean, run inspection test. • If it fails, clean the fiber and re-run inspection test. Repeat until it passes. Figure 2: Inspect Before You Connect (IBYC) Connect Launch Cable to OTDR port: 1. Inspect the OTDR port on top of the test set. 2. Inspect the fiber end face of Launch Cable. 3. Connect Launch Cable to the OTDR port.

1. Press the Power button to start the test set. 2. Press the Home button to display the Home view with the SMART TEST icon. 3. Tap the SMART TEST icon until it is yellow and highlighted . 4. Select a configuration file: • Select the EXPRESS configuration file to setup the T-BERD for 5 second acquisitions to quickly confirm loss and distance. • Select the CERTIFICATION configuration file to setup for 20 second acquisitions to confirm loss and distance AND analyze all events (slices, connectors, etc.) • Tap to select a user configuration file stored in the /disk/fiber/config folder. 5. Tap to view the SMART TEST Setup screen. 6. Laser: Tap the desired wavelength(s) to test. Select 2 wavelengths to detect bends. 7. Distance Unit: Tap the desired unit of measure for the launch cable. 8. Launch Cable: a. Tap YES if you are using a Launch Cable. b. Tap the icon to enter or measure the Launch Cable length. c. If the launch cable length is known, tap to clear existing text, enter new value on the keypad and tap to return. d. To measure the launch cable length, tap Measure and tap Confirm. The measured value will auto-populate when measurement is finished. Note: The Launch Cable should not be connected to the Fiber Under Test during measurement. 9. Alarms: Choose User for Viavi recommended Pass/Fail limits. 10. Distance Unit: If you wish to use a different unit of measure for the test results, change the unit of measure to the desired value.

The Launch Cable may be connected to the FUT via an optical patch panel (OPP) or an optical coupler: 1. If the interface to the FUT is a patch cord, connect the patch cord to an optical coupler with the same connector type. 2. Inspect the FUT connected to the coupler or OPP. 3. Inspect the other fiber end face of the Launch Cable. 4. Connect the Launch Cable to the coupler or OPP. Run Test: 1. Tap to start the test. After auto- configuration, the OTDR will perform a connection check to ensure that the connection is Good. If the Connection is Bad, disconnect the launch cable, repeat steps 1 through 3 on page 1, and repeat steps 1 through 4 above on page 3, ensuring all fiber end faces are clean. 2. The T-BERD/MTS will perform acquisitions at the configured wavelengths. Overall test results (Pass or Fail) will be displayed in a pop-up window. Tap the window to close it. 3. Results can be viewed in 2 formats. Tap the softkey to toggle views. Figure 7: Connecting the Launch Cable to the FUT with a coupler Figure 8: Connecting the Launch Cable to an OPP Figure 9: Connection Check • SmartLink view: The FUT is displayed as a series of icons representing each event (connector, splice, bend, etc.). The center of the display (Link Table) shows summary results for the entire span. Acquisitions for which all events are acceptable are marked with a green check . Acquisitions with events that exceed pass/fail thresholds for loss or reflectance are marked with a red . The lower display (Alarms) shows each event that exceeds thresholds. Softkeys can be used to alter the display: • Tap any icon in the upper display to show detailed results for the event. • Detailed results are shown for all events. Figure 10: SmartLink View

Product specifications and descriptions in this document are subject to change without notice. • Trace view: Results for each wavelength are shown in different colors in the top of the display. Each event is listed in the lower display. Any events that violate pass/fail thresholds for loss or reflectance are RED. Use the right and left arrow keys to toggle between results for each wavelength. Tap the Zoom soft key to enable the following zoom controls: • Toggle between automatic zoom and full trace view • Expand and contract the trace. Figure 11: Trace View 4. Tap the Save softkey to view File Recording Information. 5. Enter Fiber Id, Fiber Number, Locations, and Job ID as follows: • Tap field to open keyboard • Tap to clear existing text. • Enter desired value. • Tap icon to return. Note: The Job ID field identifies the Job ID and creates a folder to save the result by the same name. The default save location is JOB folder under disk. 6. Tap to save the trace in .sor format. Tap to save the trace in .sor and .pdf format. One file is saved per wavelength. Figure 12: Recording Information 7. The T-BERD/MTS will return to the OTDR results screen. 8. Tap the Assistant soft key to return to the SMART TEST Setup menu. 9. Repeat all steps on pages 3 and 4 for all Fibers under test. Figure 13: SMART TEST Setup
