CRS210 which SFP 1.25Gbps RJ45 will work?

The CRS210 has 8 ports with 1Gbps. But I need an additional port with 1Gpps. So I thought to use one of the 2 SFP+ ports and plug in a 1.25Gbps SFP module with RJ45 copper port. But the only one product from Mikrotik for this purpose will not work with the CRS210.
Has anyone experience with this switch and could propose me one type which will be working?
Thank you in advance
