摘要

Cabling choices are abundant; there are so many options these days that it is almost impossible to list them without leaving a few out. Throughout the years, the variations have continued to grow, and vendors even have their own "lines" of cable depending upon your preference. There are some things, however, that remain constant when it comes to choosing the right cable for the job. You can usually start by making the decision whether to install plenum or non-plenum cable. This choice is based on the jacket surrounding the cable, not the cable itself, which is a whole separate issue. So after you choose fiber or copper, Category 5 or Category 5e, you still have another decision to make. It may seem like a minor one, but it is important nonetheless since plenum and non-plenum are so different.
