We have all been working to replace the old 62.5 fiber cable(OM1) to achieve speeds 1GPBS+. The debate is now why not just use single mode for all short distance fiber runs? The cable itself is much cheaper than 0M4. The LC connectors cost slightly more and the optics can be more expensive. There is no minimum distance for Cisco SFP-10G-LR-S so it works good with 1 meter connections or 10KM connections. Single Mode fiber will support 100gbps currently whereas OM4 will only do 10gbps 1540ft.
