FSO或自由空间光学是一个熟悉的名称，用于电信领域的广泛应用。由于FSO具有维护成本低、部署时间短等特点，大多数应用都将其作为适当替代光纤的替代方案。在这项工作中，我们设计了100 Gbps的FSO系统相结合的模分复用（MDM）和光码多址（OCDMA）方案。在8 km的FSO链路上，采用两个拉盖尔高斯模的MDM和随机对角码传输10个信道，每个信道承载10 Gbps的数据。此外，还研究了大气干扰下MDM-OCDMA-FSO系统的性能。
FSO or free space optics is a familiar name used in a wide array of applications in the area of telecommunications. Due to its features of low maintenance cost and deployment time, most of the applications consider FSO as the alternative solution for appropriately replacing fiber optics. In this work, we have designed 100 Gbps FSO system by combining mode division multiplexing (MDM) and optical code multiple access scheme (OCDMA). Ten channels, each carrying 10 Gbps data, are transported over 8 km FSO link by using MDM of two Laguerre Gaussian modes and random diagonal codes. Moreover, the performance of proposed MDM–OCDMA–FSO system is also investigated under atmospheric turbulences.
