Cable Distances and Types
Table 17 shows one example of cable media types and maximum distances that support reliable
transmission in accordance with international standards (except where noted). Refer to the Extreme
Optics website for descriptions of optics and cables, as well as a complete list of supported cable
lengths, and a list of the cable types that are compatible with your equipment.
