Calculating Power Margin for Fiber-Optic Cable for M Series, MX Series, and T Series Routers

After calculating a link's power budget you can calculate the power margin (

P

M

), which

represents the amount of power available after subtracting attenuation or link loss (

LL

)

from the power budget (

P

B

). A worst-case estimate of

P

M

assumes maximum

LL

:

P

M

= P

B

– LL

A

P

M

greater than zero indicates that the power budget is sufficient to operate the receiver.

Factors that can cause link loss include higher-order mode losses (HOL), modal and
chromatic dispersion, connectors, splices, and fiber attenuation. Table 31 on page 286 lists
an estimated amount of loss for the factors used in the following sample calculations.
For information about the actual amount of signal loss caused by equipment and other
factors, refer to vendor documentation.
