Hello, thanks for contacting FS.COM. Yes, confirmed that the S3900-24F4S's 4 x 10G Uplinks ports can support 10G SFP+, 10G BIDI SFP+, 10G CWDM SFP+, 10G DWDM SFP+ modules, and the S3900-24F4S has another 4 x Combo SFP ports which can support 1G SFP, 1G BIDI SFP, 1G CWDM SFP, 1G DWDM SFP, 1GBASE-T modules or RJ45 cables. About the 4 x Combo ports: The Combo interface is also called an optical multiplex interface. It consists of two Ethernet ports (one optical port and one electrical port). The Combo electrical port and its corresponding optical port are logically optically multiplexed. You can select one of them according to the actual networking situation, but the two cannot work at the same time. Hope above explanation will be helpful to you, any further assistance, you can feel free to email your Account Manager, thank you. Por FS en 23 en. 2019
