Which Ethernet naming defines 10 Gigabit Ethernet over single-mode up to 40 kilometers?

Understanding Ethernet naming and reach: the suffix in 10GBASE-ER stands for Extended Reach, indicating 10 Gigabit Ethernet over single-mode fiber with the ability to span up to about 40 kilometers. This makes it the option that fits “single-mode up to 40 kilometers.” Other designs use different media and distances: SR is short-range over multimode fiber (short distance), LX uses long-wavelength single-mode fiber with moderate reach, and T runs over copper twisted pair (not fiber).
