After ex- & inserting my SFP module I got the following in /var/log/messages
err sfpswitch.py[1830]: Shutting down interface eth1
err sfpswitch.py[1830]: Bringing up interface eth1
err sfpswitch.py[1830]: EEPROM read error: [Errno 6] No such device or address
err sfpswitch.py[1830]: Switching NIC mode to phy-sfp.
The message came from /usr/sbin/sfpswitch.py:
177 def decide_sfpmode(self):
178 ec = []
179 try:
180 ec = list(EEPROM(self.i2cbus).read_eeprom())
181 d("SFP EEPROM: %s" % str(ec))
182 except Exception as e:
183 l("EEPROM read error: " + str(e))
184 return 'phy-sfp'
Where could the problem be? Hardware fault or is the SFP module not compatible with Omnia?
The SFP module I inserted was this one:
1000BASE-BX BiDi SFP 1310nm-TX/1490nm-RX 20km Transceiver Module
(very cheap: $10)
The ISP send me this media converter: Zyxel PMG1005-T20B - GPON SFU with 1-port GbE LAN
Which is the one I would by-pass.
I have tried the two SFP modules in a HP switch. They are some kind working but HP will not talk with them as they identify them self as HP equipment. Here is the output from the serial console:
%Apr 26 12:01:00:423 2000 Net24833 OPTMOD/4/FIBER_SFPMODULE_NOWINVALID:
GigabitEthernet1/0/17: This is not a supported transceiver for this platform. HPE does not guarantee the normal operation or maint.
I have borrowed a SFP module Finisar FTRJ-8519-7D-2.5 2GB and it talks fine with Omnia although I can not use the wave length.
While power is on I inserted the module and /var/log/messages writes:

My conclusion is that SFP module from fs.com does not work with Omnia for some unknown reason. So I have to find another SFP SC TX-1310nm RX-1490nm 20km module.
