T568A or T568B? Shielded or unshielded? Will I choose the right Ethernet patch panel for my application? Will this choice work with future applications? Am I getting the best overall value? With all the choices you face as you design your network and select equipment, including avail- able Ethernet patch panels, it’s easy to become confused and frustrated. Ultimately your choice of Ethernet panels should fit the applications you plan to run. ADC wrote this short tutorial to guide you through these decisions, to make them as painless as possible and offer you the best solution for your network. First, let’s ask a few key questions. Your answers will help guide you in the decision process. Next, we will briefly discuss each of the most popular options available so you can draw conclusions based on your network needs. Discovery Questions • What applications are you or do you plan to run on this network? 10/100Base-T? 1000Base-T? • What type of network are you designing? Data center? Data backbone? LAN? • Is the project a new network installation or addition to existing network? white paper • Is the installation being built to expand existing capacity with current data capabilities or is it for new, faster data applications? Answers to these questions will guide you to a particular cable type, a particular data patch panel, and the means to terminate the cable into the patch panel — whether the terminations into the patch panel involve “punchdown” cable terminations, pre-made telco-type multi-pair cable ends, or standard RJ45 cable ends. The general guidelines for network transmission capabilities segment the data network; data cen- ter and data network backbone system applications require the highest level of transmission capa- bilities, while feeds to work areas generally require a bit less. However, all network connectivity should be designed with only the highest network .
