Are you tired of messy network? As the world embraces the increasingly faster data-rate network, IT managers felt great stress over the inability to organize and create a neat rack mounted environment. Patch panels allows the easy management of patch cables and link the cabling distribution areas, which paves the way for a refreshing new approach to a neat optical network. Patch panels are usually installed on enclosures or racks to provide an easy way to organize connections. Patch panels are available in many different variations. Key design variations include: Jack module typePatch panel material typeUnshielded patch panels vs. shielded patch panelsFlat patch panels vs. angled patch panelsStandard patch panels vs. high-density patch panelsPort labeling Patch panels also allow several cable connectors to be used (LC for fiber and RJ45 for copper). Today’s article will be concentrated on the illustration of the copper patch panels, especially cat5e patch panels and cat6 patch panels.
