Ports 1 to 16 on the AT-x550-18XSQ Switch and ports 9 to 16 on the
AT-x550-18XSPQm Switch support these 1/10Gbps transceivers:
 1Gbps SX/LX SFP transceivers

10Gbps SR/LR SFP+ fiber optic transceivers

10Gbps AT-SP10TW direct connect twinax cables with SFP+
transceiver-style connectors
These items provide additional information:

They do not support 100Mbps transceivers.

They support full-duplex mode only.
SFP and SFP+ transceivers must be purchased separately. For a list of
supported transceivers, refer to the product data sheet on the Allied
Telesis web site.
