FAQ

Questions about network diagram templates

What is an FTTH OLT distribution diagram?

It's a network diagram showing how an Optical Line Terminal (OLT) at the central office distributes fiber signals through splitters and distribution points to subscribers.

What are common splitter ratios in FTTH?

Typical ratios include 1:8, 1:16, 1:32, and 1:64, often cascaded in two stages to serve more users.

How do I choose between ODC and ODP?

ODC (Optical Distribution Cabinet) is used for outdoor aggregation, while ODP (Optical Distribution Point) is closer to the subscriber, usually at building or pole level.

Can I model dual-stage splitting?

Yes, these templates support cascading splitters, for example 1:4 then 1:8 to achieve 1:32 overall.

Is this tool free?

The generator is free to use for creating and downloading your own FTTH OLT distribution diagrams.
