摘　　要：随着互联网行业的高速发展,数据中心光互连的扩展成为必然趋势,数据中心波长资源不足将成为限制数据中心发展的重要因素。提出了一种波长重用无源光互连方案,将2个信号调制在同一光载波上,通过光正交调制技术使信号实现无误码传输。同时,采用偏振复用技术,将数据中心光互连所需波长数目减少为原来的14,由此提高波长资源的利用率。With the rapid development of the internet industry,the expansion of data centers optical interconnection has become an inevitable trend.Insufficient wavelength resources in data centers will become an important factor restricting the development of data centers.this paper proposes a wavelength reuse passive optical interconnection scheme,two signals are modulated on the same optical carrier,and the optical orthogonal modulation technique is used to achieve error-free signal transmission.At the same time,polarization multiplexing technology is used to reduce the number of wavelengths required for data centers optical interconnection to 14,thereby improving the utilization of wavelength resources.
