Abstract

Traditional LANs use L2 switches, L3 routers, and xEthernet-based connections using UTP 5 copper cable. At the same time, it becomes increasingly difficult to meet the emerging requirements for increasing network bandwidth to meet the traffic requirements of new high-speed applications, reduce costs for the installation and maintenance of cable infrastructure, to reduce the power consumption of the equipment and the space occupied. To solve these problems, it is proposed to use passive optical local networks POL (Passive Optical LAN) based on PON technology. POL will not only bring great benefits to customers and does not require changes in service scheduling and network connections of user terminals, but also supports all the functions provided in a traditional LAN. POL is one of the practical approaches to implement the FTTE (Fibre to the Everywhere and Everything) concept proposed by ETSI. The article presents a draft POL design for a hotel. A feature of the POL architecture is a single fiber optic infrastructure for all services required on hotel. One fiber optic gateway is used, and ONUs with built-in router and Wi-Fi access point are located in each guestroom, providing all services (LAN, Internet access, Wi-Fi, IP-telephony, video surveillance and IPTV). In addition, special ONUs are located throughout the common areas with additional services such as emergency hotlines and IP cameras for video surveillance.
