Q: We encountered long-distance network construction problems in the company, such as office buildings too long, and the internet access point on the other side of the building, to ensure that each floor has internet access and also fast, How to solve?
A: Balanced twisted pair support for data applications is 100 meters, which is defined by international standards. The transmission of network signals over a distance of more than 100 meters will depend on the performance allowance of the cabling system, the performance allowance of network equipment, the construction situation of the site and many other uncertainties, it is difficult to get a quantified index and the transmission distance can not be guaranteed. For your case, the standard approach is to set up two telecommunications rooms on a floor, the horizontal cable division area to the corresponding telecommunications room, to ensure that the horizontal link (from the patch panel to the information outlet) length is not surpassed 90 meters.
Of course, you can also use high-performance grade, good quality cable, and module to do a direct point-to-point connection (more than 100 meters), but this line of network application support is not guaranteed, that may support xDSL or 10BASE-T signals, but may not be able to support higher rates.
Wiring design standards need to follow, if the distance is too long, you can consider adding a relay in the middle, such as with a switch or hub to connect two lines. Do not risk exceeding long-distance transmission, which can cause uncertainty in network communications.
