Generally, which of the following is not a split ratio of an optical splitter in...

Optical Splitter Overview :

Optical splitters are passive devices used in PON (Passive Optical Network) systems to divide the optical signal from the OLT into multiple paths for ONUs.

Standard Split Ratios :

Common split ratios include:

1:4 : Divides the signal into 4 paths.

1:8 : Divides the signal into 8 paths.

1:16 : Divides the signal into 16 paths.

1:32 : Divides the signal into 32 paths.

1:64 : Divides the signal into 64 paths.

Non-standard split ratios like 1:14 or 1:18 are not supported because they do not align with the design principles of PON systems.

Why B, C?

1:14 and 1:18 are not standard split ratios and are not used in PON systems.

Thus, the correct answers are B, C .
