技术领域Technical field
本公开实施例涉及通信设备技术领域但不限于通信设备技术领域，尤其涉及一种通信设备数据信号传输装置及通信设备。The embodiments of the present disclosure relate to the technical field of communication devices, but are not limited to the technical field of communication devices, and in particular, to a communication device data signal transmission device and a communication device.
背景技术Background technique
通信设备中，汇聚节点的设备或核心节点设备转发带宽需求越来越大，通信设备内部连接业务单板的高速总线速率越来越高(当前主流在研设备为56Gbps)，高速通道数量也越来越多。随着通道传输速率提高，通道单位长度***损耗越来越大，***高速通道长度越来越成为制约设备带宽容量的一个关键因素；单板功耗也因处理带宽增大和/或功能加强而越来越大，散热也已经成为***硬件总体设计的瓶颈。In the communication device, the forwarding bandwidth of the device or the core node device of the aggregation node is increasing, and the high-speed bus speed of the communication device is higher and higher (the current mainstream research equipment is 56 Gbps), and the number of high-speed channels is also higher. The more you come. As the channel transmission rate increases, the channel unit length insertion loss becomes larger and larger, and the system high-speed channel length becomes a key factor that restricts the device bandwidth capacity. The power consumption of the board is also increased due to processing bandwidth increase and/or function enhancement. The larger the heat, the more the heat has become the bottleneck of the overall design of the system hardware.
为了解决总线速率提升引入的通道***损耗增大，尤其是单通道支持到56Gbps速率的***，目前一个主要的解决方案是利用传输线的单位长度损耗较低特性，使用线缆背板的传输线缆互联***，如图1所示，该线缆互联***包括：线卡10、交换板20和线缆部件30，可以较好解决高速通道的插损过大的问题，但仍然存在线缆互联部件占用风道空间，影响***散热能力；为解决***散热，在***中对散热进行改进的线缆互联架构，如图2所示，该线缆互联架构包括：线卡40、交换板50和线缆部件60， 这种架构的线缆部件区域也可以安装风扇，线缆组件之间可以通风，散热能力较强，但同样存在线缆组件多、风阻大问题，线缆部件因线缆较多，还要满足一定的折弯半径，导致设备深度较深；另外，因为使用线缆，加工工艺复杂，线缆部件成本较高。In order to solve the increase in channel insertion loss introduced by bus speed increase, especially for a single channel supporting a system with a rate of 56 Gbps, a major solution at present is to utilize a transmission line with a low loss per unit length of the transmission line and a cable backplane. As shown in FIG. 1 , the cable interconnection system includes: a line card 10, a switch board 20, and a cable component 30, which can better solve the problem of excessive insertion loss of the high-speed channel, but there are still cable interconnection components. Occupying the air duct space, affecting the system's heat dissipation capability; to solve the system heat dissipation, the cable interconnection architecture for improving the heat dissipation in the system, as shown in Figure 2, the cable interconnection architecture includes: line card 40, switch board 50 and line The cable component 60, the cable component area of the structure can also be equipped with a fan, the cable components can be ventilated, and the heat dissipation capability is strong, but there are also many cable components and large wind resistance problems, and the cable components are more cables. It also needs to meet a certain bending radius, resulting in deeper equipment depth; in addition, because of the use of cables, the processing process is complicated, and the cost of the cable components is high.
