I am engaging a very large new smart campus (around 10 sqm, 20 large buildings, 2 train stations, multiple bus stations, and lots of audio visual devices) network design competition recently. Some system integrator proposed the Corning One GPON/XGPON as the network backbone to serve all business and applications there. I understand Cisco also has Catalyst PON product. However, I prefer our "3-tier" campus network architecture but I need your brain to help me fight back on the proposed XGPON solution.
Are there any good reasons that I may include those into my presentation to highlight the benefits and need of the 3-tier campus network architecture vs. the 2-tier GPON service model? Any comments or documents (I read the Lippis's study report before) are welcome.
