TR-512.A.4 Point to multipoint update

Most recent updates are cleanup especially terminology..

Added mesh topology implemented with couplers.

Massive overlap of wavelengths demonstrating that using couplers to make a mesh is not practical.

Couplers to form a tree seems reasonable as the use of bandwidth is equivalent to filter application.

Partial trees where broadcast to add-drop sites is potentially reasonable. 

Could relay via add-drop site but probably better to use a direct wavelength.

So in summary:

  • Poor solution for a full mesh using couplers
  • Good solution for trees]
  • Somewhere between the solution degrades to a point where it is not practical.
