Given an optical transmitter and receiver set, the most important question
concerning a system designer or integrator is the maximum implementable link
length.
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.)
- Attenuation over Corning SMF 28 Single Mode Fiber
- Reserve sensitivity should ideally be > 3dB. Less conservative safety factors may be acceptable as per the system engineer.
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.
