Performance Test
7. Connect the output connector of the light source and the input
connector of the programmable optical attenuator, using a
single-mode optical fiber.
8. Connect the output connector of the programmable optical
attenuator and the optical power meter, using a single-mode
optical fiber.
9. Set the light source wavelength to 1310 nm.
10. Set the optical power meter wavelength to 1310 nm.
11. Set the light source output to On.
12. Adjust the programmable optical attenuation to set the optical
power meter display to around –9 dBm (0.126 mW).
13. Record the optical power meter display P (dBm).
14. Disconnect the optical fiber from the optical power meter and
connect it to the optical connector for
SMF
of
Ch B In
.
15. Click Scope to display only Ch B signals on the graph.
16. Click Sampling to set to Run.
17 Record the displayed Average Power (dBm).
18. Connect the output connector of the programmable optical
attenuator and the optical power meter, using a single-mode
optical fiber.
19. Set the light source wavelength to 1550 nm.
20. Set the optical power meter wavelength to 1550 nm.
21. Set the Input Connector (Wavelength) to SMF 1550 nm.
22. Repeat steps 11 to 17.
For the MP2110A-030 or MP2110A-040, run the performance test on Ch A,
Ch C and Ch D in the same way.
