Cable Distances and Types
Table 73 on page 173 shows one example of cable media types and maximum distances that support
reliable transmission in accordance with international standards (except where noted). Refer to Extreme
Networks Pluggable Transceivers Installation Guide for descriptions of optics and cables, as well as a
complete list of supported cable lengths.
Refer to Extreme Hardware/Software Compatibility and Recommendation Matrices for a list of the cable
types that are compatible with your equipment.
