金吾财讯 | 中金公司发研报指，OCS无需光电转化，相较于电交换机具有低功耗、低延迟、高兼容等优势。OCS是直接实现光信号在光纤端口间切换的交换设备，其原理是直接对光信号进行物理路径的重构，从而在输入/输出端口之间建立专用光路。无需光电转换的特性带来低时延、低功耗、协议与数据无关的透明性和兼容性、可靠性等性能增益，但其技术原理也导致光路切换时间长、通道灵活性差的局限性，较难满足高并发、多对一、随机性强的通信负载。现阶段，OCS的技术路径尚未完全收敛，包括MEMS（微机电系统）、数字液晶、压电陶瓷直接光束偏转等方案，目前OCS参与者中采用基于3D MEMS技术的厂商较多。海外光通信公司COHR、LITE在2Q25财报中均提到已获得OCS（Optical Circuit Switch，光路交换机）初期收入，且预期相关收入将持续增长。Coherent认为OCS存有20亿美元的潜在增量市场空间。我们建议投资人关注OCS产业趋势、及该产业链中的在位厂商和潜在进入厂商。
