Use the information in this topic and the specifications for your optical interface to calculate the power
budget and power margin for fiber-optic cables.
TIP: You can use the
Hardware Compatibility Tool
transceivers supported on your Juniper Networks device.
To calculate the power budget and power margin, perform the following tasks:
How to Calculate Power Budget for Fiber-Optic Cables
To ensure that fiber-optic connections have sufficient power for correct operation, you need to calculate
the link's power budget, which is the maximum amount of power it can transmit. When you calculate
the power budget, you use a worst-case analysis to provide a margin of error, even though all the parts
