The key points from this module are:
If Germanium oxide phosphorus pentoxide or Flourine Boron Trioxide the refractive index decreases

There are two-loss mechanisms in a system Absorptive and Radiative.
Absorptive loss can be divided into Intrinsic and Extrinsic.
Radiative loss can be divided into Rayleigh Scattering and Waveguide imperfections.

In Constructive interference of the total internal reflection- wavefronts supported and discrete angles are supported.

Only specific discrete angles are allowed in fiber.
Transverse profiles need to be worked out. It does not change during propagation.

Solutions should be continuous at the core-cladding boundary.
There is only one guided mode in a single-mode fiber

Most optical communication systems use single-mode fibers.
