The 155M-2.5G PORT #1 can be used for optical Transport test
applications.
Supported rates:
OC-1/STM-0, OC-3/STM-1, OC-12/STM-4, OC-48/STM-16.
Plug the SFP module into the 8.5G-11.3G PORT #1 slot on the module.
Note: Use only EXFO supported transceivers. Refer to the SFP SONET/SDH and
OTN Optical Interfaces on page 508 for the list of supported transceivers.
Using non-supported transceivers can affect the performance and accuracy
of the test.
Note: Do not replace a SFP while the test is running to avoid distorting statistics.
First stop the test case, replace the SFP and then restart the test.
