一种保护光纤通道测试系统
摘要：
本申请提供了一种保护光纤通道测试系统中，第一单/双极性转换器和第二单/双极性转换器分别位于保护光纤通道测试系统的输入端和输出端；FPGA的第一端与第一单/双极性转换器相连接，FPGA的第二端与第二单/双极性转换器相连接，FPGA进行输入信号的延时、中断；FPGA的第三端与微处理器相连接，FPGA在微处理器的控制下对输入信号进行误码的叠加；LCD显示器和键盘分别与微处理器相连接，LCD显示器和键盘均由微处理器驱动。利用此测试系统进行测试，采用FPGA和微处理器，既能满足信号处理的要求，也能实现对LCD显示器的驱动，能够保证光纤传输系统的可靠、稳定的运行。
摘要（英）：

The invention provides a fiber protecting channel testing system. A first single/double polarity converter and a second single/double polarity converter are located at the input end and the output end of the fiber protecting channel testing system respectively. The first end of an FPGA is connected with the first single/double polarity converter. The second end of the FPGA is connected with the second single/double polarity converter. The FPGA carries out input signal delay and interruption. The third end of the FPGA is connected with a microprocessor. The FPGA carries out error code superposition on input signals under the control of the microprocessor. An LCD and a keyboard are connected with the microprocessor and driven by the microprocessor. Due to the facts that the fiber protecting channel testing system is utilized for testing, and the FPGA and the microprocessor are adopted, the signal processing requirement can be met, drive to the LCD can be achieved, and reliable and stable running of a fiber transmission system can be ensured.
