The 20th-century LAN was decentralized and hardware-centric. It was designed for “best effort” services and applications with 80% local traffic. CIOs and IT professionals prioritized their IT spend on racks and stacks of switches and cabling that filled their local data center rooms (MDFs) and communication rooms (IDFs). Technicians ran around to far-reaching end-points managing and troubleshooting networks. Security was of little concern behind the enterprise’s locked front door and wireless connectivity did not even exist yet.
Passive Optical LAN is a better architecture for the modern 21st-century LAN that never sleeps. Its fundamental architecture has centralized intelligence and management which perfectly aligns with today’s wireless (both Wi-Fi and cellular DAS), cloud, hosted/managed services, Internet of Things (IoT) and Software Defined Networking (SDN). Tellabs Optical LAN is the best choice for the modern, high-performance 21st-century LAN.
Optical Line Terminal, or OLT, is typically located in a main data center and provides aggregation and distribution of the enterprise network connectivity. It is the OLT that is connected to the Wide Area Network (WAN), High-Speed Internet and all corporate resource servers through the core router.
Single Mode Fiber, or SMF, is the optical cabling that runs throughout the building’s risers and pathways. It is the SMF that physically connects the OLT, splitters and ONTs.
Passive Optical Splitters provide the point-to-multipoint connectivity between the OLT and the ONTs. The splitters offer flexible mounting in telecom closets, wall enclosures or ceiling enclosures. They are unmanaged and highly reliable.
Optical Network Terminal, or ONT, enables optical to electrical conversion and Ethernet connectivity for voice, video, data, Wi-Fi and all other digital enterprise services and devices. ONTs are PoE enabled and subtend other powered devices (e.g. phones, cameras, wireless access points). ONT mounting can be located above the desk, below the desk or can be nearly flush-mounted in the wall. They can also be mounted in zone boxes, with optional plenum brackets and in raised floors.
Passive Optical Network Manager, or PON Manager, is the centralized intelligence and management of the passive optical network and subtended powered devices. The PON Manager provides the one console and one screen control to orchestrate consistent, repeatable, error-free IT policies and procedures.
