Application Comparison
Although, driven by the demand for higher bandwidth in data centers, fiber optics with its higher transmission rate, greater bandwidth and other advantages make its deployment in data centers occupy a larger share, especially the backbone application network; but in fact, copper cable will still be an indispensable part of the data center, and in applications such as voice transmission, power supply and other special environments, copper cable is a cable that can not be replaced by fiber optics.
Second, the unique advantages of copper cable
In the integrated horizontal cabling within one hundred meters, optical fiber is not as good as copper cable in terms of maintenance, cost and cabling. Fiber optic core is a special type of glass fiber, compared to copper in the copper cable is more fragile, in wiring and post-maintenance, fiber if not more attention will be easily broken, making its cost increase; and the current market situation, although the price of optical fiber has been reduced, but overall is higher than the price of copper; therefore, compared to fiber, copper cabling and maintenance more convenient and The cost is lower.
In the transmission of voice signals and wireless access, POE power supply systems and other power supply applications, optical fiber can not replace copper cable.
First, because copper cable is different from optical fiber is the transmission of data through electrical impulses, can support voice signals, therefore, copper cable can be used for voice transmission, but not optical fiber.
Second, because the glass fiber used in optical fiber cannot conduct electricity, while the copper in copper cable can conduct electricity, therefore, copper cable can supply electricity while making data connections, and thus is widely used in wireless access, POE power supply systems, LED-based power systems, etc.
In addition, the TIA-568.2-D standard has approved the modular plug termination link (MPTL) as an option for connecting devices, a move that will promote the growth of RJ45 copper applications, especially in the use of IP cameras in surveillance systems. At the same time, the appendix of this specification also added 28AWG specification network patch cable, and smaller specifications of copper cable will help air circulation and space utilization, so that it can be developed in high-density applications.
