Are the SFP-1000T OSP1250-CU01NCR-ZYX and SFP-10G-T-ZYX SFPP-T-ZYX Compatible with the Zyxel Switch XGS1930-28? Or what are compatible SFP, SFP+ 1000Mbit and 10Gbit Modules? Thank you for your reply.
Hi,
We find this Zyxel Switch XGS1930-28 built in the below ports.
• 24 x GbE RJ-45 ports
• 4 x 10 GbE SFP+ slots
So they should support only 10G SFP+ modules such as SFP-10G-T-ZYX, 1000BASE-T SFP should not be supported.
I suggest you deploy 10GBASE-T SFP+ module over UTP cabling, or 10GBASE-SR/LR/ER/ZR SFP+ module over fiber cabling.
