Abstract

We demonstrate 2.56 Tbit/s/port dual-polarization DWDM/DQPSK variable-length optical packet (20 Gbit/s × 64 wavelengths × 2 polarizations) switching and buffering by using a 2×2 optical packet switch (OPS) system. The optical data plane of the OPS system was constructed of multi-connected electro-optical switches and fiber delay lines. The accumulated polarization dependent loss of each optical path in the data plane was less than 5 dB. This low-polarization-dependence OPS system enabled us to handle DWDM/DQPSK optical packets (1.28 Tbit/s/port) with time-varying polarization after transmission through 100 km fiber in the field.

摘要

我们通过使用一个2×2光分组交换机（OPS）系统展示了2.56 Tbit/s/端口的双偏振密集波分复用/差分四相相移键控（DWDM/DQPSK）可变长度光分组（20 Gbit/s×64波长×2偏振）交换和缓存。该OPS系统的光数据平面由多连接电光开关和光纤延迟线构成。数据平面中每个光路的累积偏振相关损耗小于5 dB。这种低偏振相关性的OPS系统使我们能够在现场通过100 km光纤传输后处理具有随时间变化偏振的DWDM/DQPSK光分组（1.28 Tbit/s/端口）。
