采用高速示波器法和电快脉冲取样法测试高速瞬态信号。
High-speed transient signal is tested with the testing methods of high-speed oscillograph and fast electronics pulse sampling.
结果表明，在FFH- OCDMA系统中，光纤色散导致解码自相关光脉冲峰值功率和光脉冲取样能量的降低，进而导致系统误码率（BER ）的增加。
The results of simulation show that dispersion seriously reduces the peak power and sample energy on the FFH OCDMA system. Hence, bit error rate(BER) of system is increased by dispersion.
