Passive Optical LAN (POL) Kurosh Bozorgebrahimi, UNINETT

Background: PON OLT ONU ONT “Passive Optical Network” is a point to multi-point optical system with following features: Shared medium (fiber) Common control point: All traffic terminates at OLT which controls communication from/to all CPE devices No active device is located between the control point and CPEs (ONU/ONT-OLT) OLT ONT ONU Optical Line Termination (OLT): An OLT provides the network-side interface of the OAN, and is connected to one or more ODNs. Optical Network Unit (ONU): An ONU provides (directly or remotely) the user-side interface of the OAN, and is connected to the ODN. Optical Network Termination (ONT): An ONT is an ONU used for FTTH that includes the User Port function. Kilde: G984.1

Passive Optical LAN Bringing the PON FTTx concept to the LAN. It flattens and simplifies the LAN It is not limited by distance and bandwidth constrains of twisted pair networks It is secure by design, based on optical fiber and built-in encryption (ASE) Can eliminate wiring closets. Eliminate the need for midspan electronics, power and cooling OPEX saving Source: Motorola December 4, 2018

Summary POL gives an alternative way to build the LAN Should I deploy it in my network? There are a number of issues which should be taken in account before you go for this Pros and cons evaluation based on your need and requirements 4. desember 2018
