What is SFP-10G-SR?
SR represents the transmission distance of optical transceiver, SR, LR, ER and ZR are more common in 10G IEEE standard. They represent the transmission distance from short to long, you can check from below table.

We need to consider compatibility and cost when select the optical transceiver.
There are many third party manufacturers produce optical transceivers compatible with CISCO SFP-10G-SR on the market, but not all compatibility is good. So when purchase optical transceivers, we must first ensure that it is compatible with the switch.
Next is the cost, many users will choose the original optical transceiver,of course is the best if under sufficient funds. ETU-Link provides SFP-10G-SR compatible module with cost-effective, good quality and reasonable price, become the choice of more and more people.
