Data Center connectivity is provided by two broad types of cabling media—copper and fiber—and they in turn come in different configurations that offer various levels of performance.
This chapter focuses primarily on copper- and fiber-structured cabling that is initially installed in a server environment. Patch cords, which are smaller lengths of pre-terminated cable used to connect into these structured cabling systems, are discussed in Chapter 12, “Stocking and Standardizing.”
To assess the capabilities of each cable type and configuration and make an informed decision about what to install in your server environment, it is necessary to first understand how cable performance is measured.
The speed at which data can ...
