NOTE:
•
BIDI GEPON OLT fiber transceiver module is a kind of Gigabit SFP module specially used for EPON OLT
end devices. The fiber signals transmitted through SFP-GE-PX10-D-SM1490-A module can be used for
only the ONU devices with a transmission distance of 10 km (6.2 miles).
• When testing the fiber power of EPON OLT and ONU ports, please use the fiber power meter dedicated
for EPON (the fiber power meter model used in H3C is JDSU OLP-57) to ensure the correctness of the
test result.
