光学链路用光 IC 主要用于短距离数字通信用途。这种用途主要使用 POF(塑料光纤)。滨松提供专为较高速度数据传输而设计的光 IC。对于使用 POF 的光学链路用 LED,其峰值发光波长为 650 nm(红色)。
选择光学链路用光 IC 时应参考所需的通信速度、通信距离和通信编码。此外还要考虑封装尺寸和环境坚固性,从而选择所需的光 IC。有关更多详细信息,请参见数据单。
POF 具有很多优秀的特点,包括不受电磁感应影响、不需要纤芯对齐、易于安装、成本低、重量轻等。POF 广泛用于短距离的高速通信。
光学链路用光 IC 附带一个小透镜。该透镜专为 POF 设计,具有非球面表面,因此能够有效地与 POF 配合。需要小心避免与镊子等尖锐物体接触,因为这可能会刮伤透镜,导致光纤耦合损耗。
请参阅数据单,查看绝对最大额定值。较小的电流可确保最大限度减小光纤输出光耦合随时间的损失,并延长使用寿命。
目前,它们只能搭配使用 POF。
光学链路用光 IC 在设计上假设它们会用于工厂自动化、办公室自动化、家庭网络和娱乐等用途。它们不适用于可能人命攸关的用途。如果您计划在可能人命攸关的用途中使用这些光 IC,请在使用前咨询我们的销售办公室。
