A record-fast, 2 μs switching operation of an optical tunable dispersion compensator is demonstrated with a parametric tunable dispersion compensation scheme. We alternately switch two optical paths having different net dispersions with a microsecond guard interval of the compensator response and achieve successful transmissions of 43 Gbit/s non-return-to-zero on-off-keying optical signals. The error-free guard time for the switching of the two optical paths is 125 μs, limited mostly by the clock synchronization of the bit-error detector. The power penalty due to the switching of the compensator is less than 0.5 dB.
我们提出了一种参数可调色散补偿方案，演示了一种记录快速、2μs 的光可调色散补偿器开关操作。我们用微秒的补偿器响应保护间隔交替切换两条具有不同净色散的光路径，成功传输了 43Gbit/s 的非归零开关键控光信号。两条光路径切换的无差错保护时间为 125μs，主要受位误码检测器时钟同步的限制。补偿器切换引起的功率代价小于 0.5dB。
