SFP-10G-SR-x vs SFP-10G-SR

[HayamSalem79640]

What is the difference between SFP-10G-SR-x and SFP-10G-SR? 

Regarding the compatibility matrix, there are switches supported SFP-10G-SR-x and SFP-10G-SR & others support only SFP-10G-SR.

According to Cisco, it is 10GBASE-SR SFP+ Module supports multirate including 10GBASE-SR, 10GBASE-SW and OTU2/OTU2e for extended operating temperature range. Different from SFP-10G-SR,
SFP-10G-SR -X supports OTU2/OTU2e.

So, this confirms that this SFP (SFP-10G-SR-x) is not the same of (SFP-10G-SR), right?

yes. SFP-10G-SR-x have extended temperature capabilities.
