To predict the performance characteristics of single mode fibers, the following are needed:

a. Geometric distribution of light in a propagating mode: This refers to how light is distributed within the fiber. In single mode fibers, light travels in a straight line down the center of the fiber. Understanding this distribution is crucial for predicting performance characteristics.

b. Fractional power flow in the cladding of fiber: This refers to the amount of light power that is lost to the cladding, the outer layer of the fiber. The less power lost to the cladding, the more efficient the fiber.

c. Normalized frequency: This is a dimensionless quantity used in fiber optics to determine the number of modes in an optical fiber. For single mode fibers, the normalized frequency should be less than 2.405.

d. The intermodal delay effect: This is a phenomenon where different modes of light travel at different speeds within the fiber, causing a delay in signal transmission. However, in single mode fibers, this effect is negligible as there is only one mode of light propagation.

By understanding and analyzing these factors, one can predict the performance characteristics of single mode fibers.

d. The intermodal delay effect: This is a phenomenon where different modes of light in a fiber arrive at different times. However, in single mode fibers, this effect is not present because there is only one mode of light.

Therefore, all of these factors are important in predicting the performance characteristics of single mode fibers.
