Check your answers: 1. The standard for testing fiber optic patchcords is __FOTP-171__. 2. This method can be used to troubleshoot cables by__reversing the cable to test each connector individually_. 3. The standard for testing installed cable plants is __OFSTP-14__. 4. If you do look into a fiber optic cable while the system is operating (against our advice), why won't you see anything? The light is infrared and not visible to the human eye. 5. Always _clean connectors_ before testing. 6. Reference cables must match the __fiber size and connector_ of the cable being tested. 7. The "0 dB" loss reference should be set with how many reference cables? Only 1- always! 8. What determines the measurement range of your source and power meter? The output power of the source and the minimum power measureable by the power meter. 9. What must you NOT do after setting the "0 dB" loss reference ? Remove the reference cable from the source. When attached again, the power level will probably have changed. 10. True or False: The FOTP-171 "single-ended" test measures the loss of both connectors on a patchcord. 11. When measuring loss with a power meter, the __more negative_ reading will be lower power and indicate a loss. 12. Mating adapters should have _metal_ or __ceramic__ alignment sleeves. 13. How do you know if your launch and receive reference cables are good? Test them against each other using the single-ended method. 14. True or False: The reference for double-ended tests is set the same way as for single-ended tests. 15. What kind of connector will not show up as bad on a single-ended test? A prepolished/splice connector, since the termination is made with a splice inside the connector, not a polishing of the end of the fiber. |
