Please don't hesitate to contact us! Contact Us The Telecommunications Industry Association's Telecommunications Infrastructure Standard for Data Centers specifies the minimum requirements for telecommunications infrastructure of data centers and computer rooms, including single-tenant enterprise data centers and multi-tenant Internet hosting data centers. A data center occupies a room, one or more floors, or even an entire building. Most devices are often placed in a 19-inches rack, which includes network connectors, patch panels, switches, etc. For dealing with vast data transmission, network transmission performance is the most crucial part of a data center. They usually set up with the Category 6 or even Category 8 transmission performance to ensure the transmission without disruption. It's a massive challenge for technicians to build a data center with hundreds or thousands of network points and patch cords. As a result, they usually use an intelligent cabling system to ensure connection correction.
