一、模块化连接硬件的兼容性 目前标准研究组织,正在开始起草制定下一代布线系统规范的发展方向(如6类和7类),与现存的布线类和级的兼容性就无法得到保证。结果是,向后兼容性就变成了电信通讯工业中棘手的议题。 国际标准化组织同意,对于新的平衡布线信道,其频率上限将扩展到至少能使衰减和功率相加(多干扰)近端串扰相交的频点。“6类”和“E级”规范将支持用于信息插座的标准8芯模块化接口,并且能保证在200MHz的频率下,衰减和功率相加串扰之间的差为正。“7类”和“F级”
First, the compatibility of the modular connection hardware The current standard research organization is beginning to draft the development direction of the next-generation wiring system specification (such as 6 and 7), and the compatibility with the existing wiring and class cannot be guaranteed. As a result, backward compatibility has become a thorny issue in the telecommunications industry. The International Standards Organization agrees that for a new balanced wiring channel, the upper frequency limit will be extended to at least the frequency at which the attenuation and power add (multi-interference) near-end crosstalk intersects. The “Class 6” and “Class E” specifications will support a standard 8-core modular interface for information outlets, and will ensure that the difference between attenuation and power-added crosstalk is positive at 200 MHz. “Class 7” and “Class F”
