Hi, thanks @all for help and offers.
I was thinking of changing the polarity but the cable which I got from my provider lacks that possibility. It looks like it is glued together. Well, it WAS glued together - I broke it and plugged the LC connectors into the SFP. Now guess what: the darn thing is up and running! Am I too naive to expect a E2E test done by provider is reliable? Do I have to expect to break the connector and switch the polarity so that I can use that thing?
