FTTH & PON

FAT vs FDT is decided by where the feeder ends: the FDT breaks out and splits, the FAT makes the last drop connection, with sizing math and a checklist.

Splitter ratio is a budget decision: subtract worst-case splitter loss from your PON budget, then pick the largest ratio that still leaves a design margin.

FTTH network topology design is one ordered decision: density and take rate pick the topology, which then places the splitters and sets the split ratio.

An optical network terminal (ONT) turns fiber light into Ethernet at your premises. Here is how the OLT, ONU and the ODN that links them actually fit together.

AON uses powered switches and dedicated fiber; PON shares one feeder through passive splitters. Compare reach, optical budget, power and cost before you commit.

GPON vs EPON vs XGS-PON is three questions, not one. Choose by the ODN you already own, the split ratio it can carry and the upstream your services need.

FTTP vs FTTH vs FTTB vs FTTD compared: four fiber deployment models, four stopping points — how each one changes speed, upgrade path and install cost.

FTTB meaning explained: Fiber to the Building runs fiber to a building's telecom room, then copper or Ethernet to each unit — and why the cable build matters.

Active splitters require external power and amplify the signal; passive splitters need no power but introduce inherent loss. Learn which type fits your network.

From 1×2 to 1×64, from FBT to PLC, this guide covers every major type of optical fiber splitter — how each works, when to use it, and how to choose the right one for your network.

Every passive PLC splitter adds an unavoidable signal tax. Learn exactly how many dB each split ratio costs — from 1×2 (~3.1 dB) to 1×64 (~20 dB) — and how to fit it into your link budget.

FTTH runs fiber directly to individual homes; FTTP is the broader term covering fiber to any premises — homes, offices, apartments, or campuses. Learn which fits your use case.
