    Hi @Username_is_reserved,

    Yes, please be assured to purchase the equipment as GS2220 do support SFP-LX-10-D and 50m fiber cable is in the support range.

    Thanks maybe I heard in the years ago that Modules who are intend for long range communication like SFP-ZX-80-D using high power LED, Laser when use with a "short" Cable like 50m, 100m destroy the other end do to the hight power output?

    Another stupid question I bought a Server who have a Network Card who only Transceivers can put in. How do I know if the are compatible with other on the Glas Fiber side?

    It depends on every SFP module transmit power and receive power range specification.
    If the "transmit power" > "receive power range", you will need to add a fiber attenuator for short fiber cable 50m/100m to avoid SFP module destroyed.
    Reminder: Only SFP module has a chance to be destroyed, fiber cable is not affected.

    Another stupid question I bought a Server who have a Network Card who only Transceivers can put in. How do I know if the are compatible with other on the Glas Fiber side?
    In brief, glass fiber cable have two types; SMF/MMF, SMF only supports single-mode fiber cable. 

    Hope it clear.
