SAFETY WARNINGS Read First: Safety and Operational Information The international electrical symbols used on the instrument or in this manual are described below. Warning or Caution: Risk of damage or destruction to equipment or software. See explanation in the manual. Warning: Risk of electric shock. - Page 3 Class 1 and Class 2 Laser Products Under no circumstances should a user look directly into optical connectors. Some sources produce invisible radiation that can permanently damage your eyes. Under no circumstances should a user view the device’s optical connectors using magnification unless the device is detached from the SCT series tester.

Page 10: Cleaning Connectors And Adapters
Cleaning Patch Cord and Fiber Connector End Faces Megger recommends using a cartridge or pocket style dry cleaner to clean fiber optic cable connector end faces. Follow the cartridge or pocket style dry cleaner manufacturer’s directions. -
Page 11: Cleaning Sct-Mma/Sma Fiber Optic And Bulkhead Connectors
Cleaning SCT-MMA/SMA Fiber Optic and Bulkhead Connectors The best method for keeping the SCT-MMA/SMA and bulkhead connectors clean is to cover the connectors when not in use and only insert clean fiber optic patch cord connectors. Cleaning the SCT-MMA/SMA and bulkhead connectors should always be followed by inspection to determine results. -
Page 12: Test Management
TEST MANAGEMENT Managing the test environment of the SCT is all organized under the HOME page using the “Manage” functions. These functions allow the user to manage Projects, Cables, Test Limits and Stored Results. PROJECT FOLDERS The Project Folder contains all certification testing parameters, results and information about a specific test site. A project folder is created by selecting the required certification testing parameters and then saving the selections in a project folder. -
Page 13: Managing Project Folders
Fiber optic projects require the following test parameters: Field Description Project Determines the project name. Media The media type selection twisted pair, singlemode fiber or multimode fiber determines what test parameters are required and what adapter is expected. Test Limit The test limit selection determines what tests to perform and how to evaluate the results. - Page 14 Page 1 Select “Projects” from the “HOME” menu using the navigation keys and press [ENTER]. Select “Create Project” and press [ENTER]. Create a Project Name - Navigate to the project name field and press [ENTER]. Using the editor create a new project name. When complete navigate to the Save hyperlink and press [ENTER].

Page 15: Cables
Selecting bi-directional testing will measure and report loss on each fiber at two wavelengths in both directions. When selected the user will be asked to swap fibers on both adapters. Do not disconnect the reference cords from the adaptors, instead disconnect and swap the fibers under test at the first adapters. -
Page 16: Test Limits
Create Cable: Using the navigation keys select “Cables” from the “HOME” menu, under the “Manage” window and press [ENTER]. Select “Create Cable” and press [ENTER]. Select a cable media type and press [ENTER]. Enter the cable parameters then navigate to “Save Cable” and press [ENTER]. Delete Cable: Using the navigation keys select “Cables”... -
Page 17: Preparing To Test
Establish a fiber optic reference only after the SCT Primary and Secondary units and the SCT-MMA/SMA fiber optic adapters have been on for five minutes. Allow additional time for the adapter to reach ambient temperature if the adapters have been stored above or below ambient temperature. -
Page 18: Secondary Mode Reference Using Test Method B
Secondary Mode Reference Using Test Method B If setting a Method B reference using the Megger provided duplex reference cords use both cords to eliminate removing one cord from the adapter and invalidation the reference. If the fiber optic link uses non-SC style connectors refer to Appendix B for establishing a reference using the modified test method B setup. -
Page 19: Loopback Mode Reference Using Test Method B
Loopback Mode Reference Using Test Method B Setting a Method B reference using the Megger provided duplex reference cord. If the fiber optic link uses non-SC style connectors refer to Appendix B for establishing a reference using the modified test method B setup. -
Page 20: Certifying Fiber Optic Cabling
CERTIFYING FIBER OPTIC CABLING Certification requires that the appropriate project is selected and a reference is established prior to testing. The reference measurement is invalidated if the reference patch cord is disconnected from the SCT_MMA/SMA fiber optic adapter. Disconnecting and re-connecting a reference patch cord will alter the optical characteristics resulting in a different reference loss power. -

Certifying Duplex Cable Using Test Method B All necessary certification test information is displayed and all required certification tasks are available from the Autotest menu to maximize productivity. If the fiber optic link uses non-SC style connectors refer to Appendix B for certifying using the modified test method B setup. -

Page 26: Fiber Optic Certification Results
FIBER OPTIC CERTIFICATION RESULTS The SCT Autotest carries out all tests required by industry standards. If a test is not applicable to the selected test standard the test will be marked ‘informative’ and will not be evaluated for certification. RESULT SUMMARY The result summary showing all measurements in summary format is displayed first when viewing results. - Page 27 Length Length displays the calculated length of the fiber optic link under test. Simplex (loopback mode) length calculates the total fiber optic link delay from the referenced primary output to the referenced primary input fiber optic connections. Duplex (secondary mode) length calculates ½ of the total fiber optic link delay from the referenced primary output to the referenced secondary input fiber optic connections and the referenced secondary output to the referenced primary input fiber optic connections.

Page 28: Visual Fault Finder
VFL OPERATION The VFL is enabled on SCT-MMA or SCT_SMA fiber optic adapter by pressing the VFL enable button. The VFL output operates independently from the SCT and can be enabled or disabled at any time. The first press of the VFL enable button enables continuous VFL mode as indicated by a constant red VFL mode indication LED. -

Caution Establish a fiber optic reference only after the SCT Primary and Secondary units and the SCT-MMA/SMA fiber optic adapters have been on for five minutes. Allow additional time for the adapter to reach ambient temperature if the adapters have been stored above or below ambient temperature. -
Page 36: Figure 10 Alternate Method B Certification Testing
When the reference measurement is complete disconnect the center SC to SC fiber optic reference cord and add the two short duplex patch cords converting SC to the connector style used by the link under test which will produce Test Method B results. Alternate Test Method B will accommodate links with the same or different connectors at each end of the link under test. - Page 37 T +1 416 298 6770 F +1 416 298 0848 E casales@megger.com Megger products are distributed in 146 countries worldwide This instrument is manufactured in the United Kingdom.
