Use the informaon in this topic and the specicaons for your opcal interface to calculate the power
budget and power margin for ber-opc cables.
TIP: You can use the Hardware Compability Tool to nd informaon about the pluggable
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-Opc Cables
To ensure that ber-opc connecons have sucient power for correct operaon, 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
