The SFP-10G-SR-S and its mates the -LR -ER and -ZR variants have the same 10 Gbps Ethernet transmit and receive optical thresholds as their non-S equivalents.
They do only operate from 0-70 C as they do not offer extended (-5 to 85 degrees) or industrial (-40 to 85 degrees) versions.
Finally, they will not operate over OTN (ITU G.709 framing) or WAN-PHY (OC-192 framing).
