What Is the Maximum Connection for between OLT to Splitter and to ONU/ONT

Hello, friend. 

It's nice to meet you in the community. 

We're working on your problem. Please be patient.

Hello, friend.

The number of optical splitters that can be connected to the OLT depends on the split ratio of the external port (SFP) of the board. The number of fiber cores from the OLT to the optical splitter depends on the number of SFP ports. The split ratio refers to the maximum number of ONTs that can be connected to the OLT. 

optical splitter is classified into the level-1 optical splitter, level-2 optical splitter, and level-3 optical splitter. 

The number of optical splitter to be connected depends on the plan. 

However, as the number of branch optical paths increases, the optical transmission distance is affected.

Thanks！

Hello, my friend! 

I didn't understand your question, 

But through the questions, you asked today, 

I suggest you learn the principles of GPON. 

How many optical splitter can be connected to the OLT? 

When you're learn done with GPON, you know that the question is not how many optical splitter you can connect to, but what you need. 

Level-1 optical splitter can be further divided by level-2 optical splitter, and level-2 optical splitter can be further divided by level-3 optical splitter.

Thanks！
