There are a number of 10GbE implementations. Of these standards, 10BaseSR is designed for LAN or MAN implementations, with a maximum distance of 300 meters using 50 micron multimode fiber-optic cabling. 10BaseSR can also be implemented with 62.5 micron multimode fiber, but is limited to 33 meters in this configuration.
10GBaseLR and 10GBaseER are designed for use in MAN and WAN implementations, and are implemented using single mode fiber-optic cabling. 10GBaseLR has a maximum distance of 10km, whereas 10GBaseER has a maximum distance of 40km. Table 6.
