Appendix C

Visual Guide to

Connectors

Throughout this book, you learned about several different cabling and connector options that may be used on networks. Some, such as RJ-45, are very common, whereas others, such as Fiber LC connectors, are used only on newer high-speed networks. So that you can compare such connectors and ensure that you understand their differences, this Appendix compiles drawings of the connectors and a brief summary of their application in a simple table.You must be familiar with the most popular types of connectors to qualify for Network+ certification.You can find more detail about these connectors and the networks on which they are used in Chapters 3 and 5.
