Calculating the Fiber-Optic Cable Power Budget for QFX Series Switches

Calculate the fiber-optic data link's power budget when planning fiber-optic cable layout and distances to

ensure that fiber-optic connections have sufficient power for correct operation. The power budget is the

maximum amount of power the link can transmit. When you calculate the power budget, you use a
