What passive optical LAN is
Passive optical LAN (POL) uses the same PON technology as fibre-to-the-home inside a building or campus. An OLT in the main equipment room connects through passive optical splitters to ONUs near users, devices and access points.
Why owners like it
Fibre runs long distances without intermediate switches, so floor telecom rooms can shrink or disappear. Less active equipment means lower power, cooling and maintenance, and fibre's capacity is ready for future upgrades.
Where it fits
Hotels, hospitals, universities, residential towers and large offices with many floors or buildings benefit most. Copper switching still makes sense for dense equipment rooms and data centers.
Designing it well
Plan split ratios for the bandwidth each user needs, choose ONUs with PoE for cameras and access points, and keep a fibre protection path for critical areas.
Navijin and POL
The upcoming Navijin Optical Access family, together with Navijin Wi-Fi, switching and security, will let partners design fibre-first buildings end to end.
