耦合器、分束器及合束器
此类器件基于光波导倏逝场耦合效应，核心功能是实现光信号在两根或多根光纤之间的精确功率分配与组合，且不改变信号频谱成分。我们的产品工艺成熟，具备插入损耗低（<0.8 dB）、回波损耗高（>50 dB）及方向性好（>55 dB）等关键优势，广泛应用于无源光网络（PON）、光纤CATV、高功率光纤激光器合束及数据中心互联。产品阵容涵盖等比例或非等比例的单模/多模标准耦合器、双/三窗口宽带耦合器、微型耦合器、熔融拉锥型WDM以及用于信号精确监测的Tap耦合器；此外，还提供适用于高通道分配的PLC波导分路器、偏振合束/分束器（PBC/PBS）及机械可调分束/合束器，满足多样化的光功率分配和偏振管理需求。
