摘要
针对解决同步数字体系(SDH)骨干网传输系统中通信节点的规模问题,提出了一种高集成度接入SDH骨干网的方法,该方法基于“单FPGA+多个光电转换模块”结构,在单片FPGA上可以实现多达20个通道STM-16速率等级信号的无缝接入,与已有方法相比,具有集成度高、低功耗、可靠性好和功能灵活配置等优点,该方法已成功应用在某型主干网通信系统中,应用结果表明,该方法可以实现完全符合SONET/SDH标准的并-串-光的发送和光-串-并的接收功能,大大降低了通信节点的规模,具有重要的实际意义和应用价值。
A high integration access method for SDH backbone network is presented. Based on the architecture of " single FPGA + multiple optical: electric devices", it can realize the seamless access to twenty optical fiber lines of STM-16 level. Compared with the traditional methods, It possesses the characters of high-integration, low--power, good reliability and flexibility. This method has been successfully illustrated in the backbone network communication system, implementing the functions of parallel--to--serial--to optical transport and optical transport to--serial--parallel, fully compliant with the SONET/SDH standard. It is of much great practical significance and applicational value in solving the scale problem of the communication nodes in the backbone network communication systems.
