A passive optical LAN comprises centrally managed optical line terminals (OLTs) connecting to optical network terminals (ONTs) throughout an airport using single-mode fiber optic cable and passive optical splitters. Each ONT offers multiple network ports to connect and power devices. Airports have a lightweight, yet resilient fiber-based passive optical LAN (POL) that: The solution features a simple, flat. SITA Passive Optical LAN (PON) infrastructure with Tellabs unveiled for ultra-reliable, scalable and secure connectivity across airport campuses and other critical operational areas The increasing pressure to support data-intensive applications with real-time communication across sprawling airport.

Passive optical LAN technology offers solution to airport technology needs of today and tomorrow. With single-mode fiber from an OLT to ONTs via optical splitters, a passive optical LAN can span long airport distances to support a wide range of technologies without the need to deploy traditional IT. The SITA PON system offers a centralised, fibre-based network for connectivity in core airport areas and remote facilities. The new fibre-optic communication solution aims to meet the increasing demand for real-time, high-bandwidth connectivity in airports.
