5. 关键技术特性(Key Technical Features)
5.1 FBC(Fused Biconic Coupler)熔融拉锥技术
F-tone Networks FT-13 系列 8dB 衰减器采用 FBC(Fused Biconic Coupler,熔融拉锥)技术,是一种经典的无源光器件制造工艺:
- 🚀 熔融拉锥原理:将两根(或多根)光纤在高温下熔融并同时拉伸,形成双锥形耦合区,通过控制拉伸长度和熔融温度来精确控制耦合比
- 🚀 低附加损耗:由于是物理熔融结构,光信号在耦合区几乎没有附加损耗
- 🚀 高方向性:≥50dB 方向性确保光信号单向传输,无后向反射
- 🚀 宽带宽:1500-1650nm 宽工作波长范围,覆盖 C+L 波段
