利用光纤非线性环路镜成功地将２．５Ｇｂｉｔ／ｓ的归零码光脉冲变换了２０ｎｍ的距离。在最佳波长变换处对变换信号进行了１小时的误码测量，采用２２３－１伪随机码序列，误码为１．３×１０－１４。信号光和探测光脉冲宽度分别为２８ｐｓ和３７ｐｓ，中心波长分别为１５３３ｎｍ和１５５３ｎｍ。
The 2.5Gbit / s return-to-zero optical pulse is successfully converted to a distance of 20nm by using a fiber nonlinear loop mirror. In the best wavelength conversion at the conversion signal for 1 hour error measurement, the use of 223-1 pseudo-random code sequence, the error code is 1.3 × 10-14. Signal and probe pulse width were 28ps and 37ps, the center wavelength was 1533nm and 1553nm.
