协议原文:
The operating ranges for 10GBASE-S are defined in Table 52–6. A 10GBASE-S compliant PMD supports
multimode fiber media types listed in Table 52–6 according to the specifications defined in 52.14. A PMD
that exceeds the operational range requirement while meeting all other optical specifications is considered
compliant (e.g., a 400 MHz km 50 μm solution operating at 80 m meets the operating range requirement of
2 to 66 m).

The operating range for 10GBASE-L PMDs is defined in Table 52–11. A 10GBASE-L compliant PMD
supports Types B1.1 and B1.3 single mode fibers according to the specifications defined in 52.14. A PMD
which exceeds the operational range requirement while meeting all other optical specifications is considered
compliant (e.g., operating at 12.5 km meets the minimum range requirement of 2 m to 10 km).
