Optical power budgets in PON
In PON networks, transceivers and receivers in the OLT and ONT use optics with classes defined by PON standards. For each optical class, there is a minimum and maximum value, defining the
Optimizing Your PON Optical Link Budget.
Together, the total loss (attenuation) of each of these elements must be within the optical power budget (max delta between transmitter output and receiver input levels) of the PON system.

Cisco Routed Passive Optical Network Deployment Guide, Release
You have the option to utilize a scalable model based on your bandwidth requirements, choosing between PON pluggable optics or Ethernet optics for your requirements. This solution
Optical Splitters: Split Ratios, Splitting Architectures & PON Network
Choosing the right split ratio depends on three interrelated factors: distance, bandwidth demand, and cost. Optical signals lose power (attenuation) as they travel through fiber—typically
Introduction to Passive Optical Network Splitter Architectures
For every 2X increase in split ratio, power is reduced by roughly 3 dB. In most cases, the power out of each leg is equal, but we''ll discuss a version where the power coming out is unequal amongst legs.
How Many ONUs Can an OLT PON Port Support?
An OLT PON port can theoretically support up to 64 ONUs in EPON and up to 128 ONUs in GPON. However, the ideal split ratio depends on multiple real-world factors including bandwidth
