光能计算工具
对一套光纤的发射和接收设备来说, 系统设计者最关心的问题是最大可连接的长度.
To use the Optical Power Budget Calculator select a launch power and receiver sensitivity, then enter values for other required information (Link Length, Number of Patch Points, etc.)
可以尝试用光纤设备选择指南来帮助选择.
- 衰减计算是在 Corning SMF 28 单模光缆
- 预留的敏感度最好大于 3dB. 然而, 每个系统工程师可以根据不同情况来决定是否接受更小的安全系数.
How do I find... ?
A transmitter's Optical Output Power appears under the Optical Output heading on the product's spec sheet and web page.
A receiver's Optical Sensitivity appears under the Optical Input heading on the product's spec sheet and web page.
