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.
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.
