Dedicated GPON vs Hybrid GPON (With Switches)

Dear All,

The thing is creating a closed security network with multiple edge elements (4000+ - Camera/Access Control/Barrier), and this network deploying is GPON.

and the network is spread in one huge campus with multiple building and floors but confined in one area only.

So the basic question is what would be the Pros and Cons of deploying Dedicated GPON (With only OLT-Fiber-ONT/ONU-Cat6A-Edge Element) vs Hybrid GPON (With OLT-Fiber-ONT/ONU-Cat6A-Switch-Cat6A-Edge Element).

Both are possible as of now but what would be the better option or what would be thing that would be at stack. Which is better or have limitations In terms of manageability, redundancy, maintenance, scalability and things that should be also incorporated in.

If any other details are required than please let me know.

Server and other things would be same in both.

Thanks in advance.
