I have a problem with creating optical connection between CSS610 and RB2011UiAS-2HnD. Link is flapping and it is not usable.
SFP+1 Mikrotik S-31DLC20D SG31231403368 13-04-26 1310nm single-mode fiber 39C 3.205V 19mA -5.327dBm -24.815dBm
Connection with same SFP module between RB2011UiAS-2HnD and RB2011UiAS-2HnD is working correctly:
name: sfp1
status: link-ok
auto-negotiation: done

full-duplex: yes
tx-flow-control: no
rx-flow-control: no

I tried everything changing link to manual negotiation on both sides, but without success. Do you have any idea why same module acts differently in different device?
