measurements and operation. Always clean all test jumpers before conducting tests. Turn on OPM (optical power meter). 1. Select the appropriate fiber optic test jumper. The fiber type of this jumper must 2. be the same as the fiber type normally connected to the output being measured. Mount the appropriate adapter cap on the OPM port. This adapter cap must match 3. the connector on the end of the test jumper you will connect to the OPM. Connect one end of the test jumper to the OPM adapter cap and the other end to 4. the optical output to be measured. Press [ 5. λ] to select wavelength that matches the nominal wavelength of the source being measured. Press 6. [dB/dBm/µW] to display power in [dBm] or press and hold to display power in [µW]. OPM5 only: 7. Press [Store] to save the displayed measurement in the next available memory location.

Step I - Set the Reference (One Jumper Method) Turn on the OPM and OLS. Allow OLS to stabilize (minimum of 2 minutes). 1. If not using WAVE ID feature, set both instruments to the desired wavelength. 2. Select transmit and receive jumpers (fiber type must match link to be tested). 3. MM: 4. Wrap and secure transmit jumper five times around mandrel. SM (TIA testing only): Make and secure 30mm loop in a transmit jumper. Clean both ends of the transmit jumper! Connect the transmit jumper to the OLS output port (MM or SM respectively). 5. Mount adapter cap on the OPM (must match free connector on transmit jumper). 6. Connect transmit jumper (free end) to the OPM. Display optical power in [dBm]. 7. If measured power is outside of the normal range (specified by manufacturer), 8. clean all fiber connections or replace the transmit jumper. Repeat steps 4 - 7. Set reference level: on OPM, press and hold [Ref/Set] until [HELD SET] is 9. displayed to store currently measured level as the new reference level. Once set, OPM switches to [dB] mode. OPM should display [0 dB] ± 0.05 dB. OLS OPM 0 dB Transmit jumper Mandrel wrap - MM (shown), or 30 mm loop - SM 4 5 7 6

Step II - Verify Test Jumpers Disconnect the transmit jumper from the OPM. 10. Do not disturb the transmit jumper at the OLS end! If needed, change OPM adapter cap to match receive jumper connector. 11. Clean both ends of the receive jumper! Connect the receive jumper to the OPM. 12. Mate free ends of transmit and receive jumpers using the appropriate adapter. 13. Verify that the insertion loss of this mated connector pair is under 0.75 dB - 14. maximum allowed by TIA (Noyes recommends 0.4 - 0.5 dB typical): Observe the displayed value - insertion loss of the test jumpers in [dB]. –– If value is not acceptable, disconnect transmit and receive jumpers at the –– adapter, clean free ends of both test jumpers and repeat steps 13 & 14. If value is still not acceptable, replace test jumpers and repeat steps 1-14. –– If loss value is acceptable, disconnect transmit and receive jumpers at the adapter. 15. Move the OPM and OLS to opposite ends of the link to be tested. 16. OLS OPM Mandrel wrap - MM (shown), or 30 mm loop - SM Transmit jumper Do NOT disturb this connection Adapter Receive jumper 13 12 11 0.4 dB

Step III - Measure Multimode Link Insertion Loss Connect free ends of transmit and receive jumpers to the link under test. 17. Clean jumper end that connects to patch panel prior to every test! OPM will measure and display the insertion loss of the link under test. 18. Perform one of the following: 19. If using OPM4: Record link insertion loss at the current test wavelength. If using OPM5: Press the [Store] key on the OPM5 to save the displayed measurement in the next available memory location. Repeat steps 17-19 for all links to be tested at the current wavelength. 20. © 2010 AFL Telecommunications, all rights reserved.
