Cable Distances
Table 10 shows cable media types and maximum distances that support reliable transmission in
accordance with international standards, except where noted.
* Proprietary to Extreme Networks. Connections between two Extreme Networks 1000BASE-LX interfaces that use 10/125 μm
single-mode fiber can use a maximum distance of 10,000 meters.
