Hello there,
I am trying to use a Sercomm FSG202 GPON module on a Mikrotik hEX-S (RB760iGS).
I have installed OpenWRT Snapshot, as it is noted that fiber module does not work with 21.02 (https://openwrt.org/toh/mikrotik/rb760igs#sfp)
When I insert the module, I have those messages in dmesg:
[ 51.548295] sfp sfp1: EEPROM base structure checksum failure: 0xc1 != 0xff
[ 51.555156] sfp EE: 00000000: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................

The command ethtool -m sfp
is only able to show FF
s in values.
The module works fine in my RB3011:

In comparison, here are some tests with an Elfcamm copper module.
