Any suggestion will be highly appreciated
I have a setup:
- Internet Service Provider which use EPON technology (they use BDCOM P3600-08E on their end)
- On my side Mikrotik 5009 router
- With SFP module FoxGate ONU 1001XP-SFP
This setup is working, but I was not really happy with SFP module. It really overheats. Router shows that eeprom-checksum: bad so it does not shows any additional info from SFP module, etc.
I decided to switch it with one from FS.COM. I did tried to replace my SFP module with Generic Compatible EPON ONU SFP 1310nm-TX/1490nm-RX 1.25G-TX/1.25G-RX Class PX20+ 20km DDM SC SMF Optical Transceiver Module (Industrial).
But with no luck, unfortunately.
Router can perfectly see the module and read it’s info.


But connection is not established. ![]()


It just constantly generates Rx FCS Errors
and could not receive anything.
Would appreciate any ideas how to troubleshoot it.
