Sorry for my bad English.
I want to use Mikrotik S+85DLC03D SFP modules with Linksys LGS552-EU ethernet switches.
The recommended (by Linksys) SFP module for this switch is the Linksys LACXGSR.
I never used SFP modules and optical cable before this time.
I see some technical information the SFP modules datasheets. So I think the Mikrotik S+85DLC03D SFP modules will working with Linksys LGS552-EU switches. Or this is not so simple?
The Mikrotik SFP module: http://routerboard.com/Splus85DLC03D
The Linksys SFP module: http://www.linksys.com/eg/p/P-LACXGSR/
They are thoretically compatible, difficult to know if they will work without actually testing, as linksys may lock SFPs to their own brand, or another issues may arise.
I have two Linksys LGS552-EU 48 ports ethernet switches. I bought two Mikrotik 85DLC03D SFP modules and the optical link is working good with 10GB speed between this switches!
