BAIJIAN - Third party testing organization
The PDS (Premises Distribution System) is a set of cabling systems specially designed to meet development needs. For modern buildings、 it is like the nerves inside the body. It uses a series of high-quality standard materials and integrates voice、 data、 image、 and some control signal systems in a modular combination using a unified transmission medium. After unified planning and design、 it is integrated into a standard wiring system. With the rapid development of demand for optical fiber、 fiber optic cabling systems will become the direction of development. Distance limitation is an inevitable choice for floor connections and interconnections within the park using optical fibers. In the construction of the park network、 it is generally required that optical fibers be connected to the community and to the building. At the same time、 the cost of fiber optic cabling is significantly decreasing、 making both multimode and single-mode fibers highly cost-effective. The computer network adopts a fiber optic hub、 and only 2 fibers are required for every 48 data information sockets. So、 a 4-core optical cable can be connected to 96 data information sockets through a hub. As is well known、 the horizontal wiring length of UTP should not exceed 90 meters. After removing the termination allowance and upper and lower wiring、 the effective length is only about 70 meters. That is to say、 using a 4-core optical cable on the backbone side (input port) of the hub can cover 96 data points within a 70 meter horizontal range、 with an average of at least 1.3 data points per meter. With such a high distribution density、 there should be no need to install copper cables
