Fiber-optic link signal loss budget
Every fiber-optic link has some signal loss (measured in decibels). Many
factors affect decibel loss, including:
Length of fiber-optic cable
•
Transmitter optical output power
•
Operating wavelength
•
• Fiber attenuation
• Fiber bandwidth
Receiver optical sensitivity
