Selecting Cable; Cable Distances; Rj-45 Connector Jackets - Extreme Networks BlackDiamond 8806 Hardware Installation Manual

Selecting Cable

This section provides information that is helpful when you must select the cables to be used with the
BlackDiamond 8800 series switch.

Cable Distances

Table 17 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.

RJ-45 Connector Jackets

Use RJ-45 cable with connector jackets that are flush with the connector or that have connectors with a
no-snag feature.
Using cable with jackets that are wider than the connectors can cause:
Connectors that are not properly aligned with the port.
●
Crowded cable installation, which can cause connectors to pop out of the port.
●
Figure 40 shows examples of connector jacket types that are not recommended, as well as those that are
recommended.
