3. 3 drivers for LAN upgrade
Convergence
High capacity
Mobility
Legacy LAN typically need parallel sub- systems (equipment, cabling and management) to deliver voice, data, video, CCTV, security, WiFi, public announcements…
Remove the bottlenecks with a Gigabit network to increase the efficiency and communication between employees, suppliers and customers
New WiFi technologies require refresh of all LAN switches with N- BASE-T and replacement of cables.
802.11ac Wave 1 - require 1Gb/s
802.11ac Wave 2 – require 3.6Gb/s
802.11ax – require 10Gb/s
Reduce costs with one network to deliver all services
Improve the business performance
Efficient WiFi backhaul today and in the future
Being smart with your investment means investing the same amount of money in new technology that will help you answer the challenges

10. POL Benefits Operations Traditional LAN POL Equipment management
Distributed network needs more personnel to manage all switches across multiple locations: keep SW up to date, monitor, handle alarms, troubleshoot, replace devices etc
Centralized intelligence to manage the entire network:
OLT is the only device that needs maintenance
End-point (ONT) is a thin-client device, managed centrally
Cable management
Bulky cables: more difficult
to maintain, repair, replace
Cabling infrastructure is simple and more reliable:
fiber is more flexible than copper, less likely to be damaged during installation
fiber is more resistant to water and temperature
Another operational inefficiency of these legacy copper-based networks is their local management at each Ethernet switch. Skilled IT pros are forced to execute moves/adds/changes (MACs) by interfacing directly with all these switches spread across multiple physical locations, a process that increases the chances of human error and adds to the expense of everyday LAN operations.
The Optical LAN is characterized by a shared point-to-multipoint architecture, a passive optical distribution infrastructure and near-futureproof single-mode fiber connectivity. Similar to cloud-based networks, the OLAN architecture shifts network intelligence to the core and centralizes the management of all far-reaching endpoints. Just as cloud-based computing centrally locates resources for sharing by many users to save energy, space, capital costs, and operational costs, OLAN does precisely the same
Optical LAN, with its central management, lays the foundation for software-defined networking (SDN), thereby allowing the global automation of:
n Fault (alarms, diagnostics, and troubleshooting)
n Configuration (provisioning and upgrades)
n Automation (OSS, backups, and restorations)
n Performance (reporting)
n Security (user roles and access controls)
n Inventory Management
The intelligence required to manage all endpoints and services resides in the central management system and OLT, an approach which accelerates moves, adds, and changes while reducing human error. The combination of more machine-to-machine communications and fewer human touches improves network availability. Large businesses lose about 4% of annual revenue because of network downtime, and the human factor is responsible
for 50%–80% of all network outages.
Because an ONT is a thin-client device, it does not store user and provisioning information; only the OLT stores all user policies. IT professionals can install ONTs behind lockable covers or inside walls, with faceplate screws alarmed through the intelligent, centrally located management system. On an ONT, the default state for all Ethernet ports is “disabled,” which means that attackers cannot penetrate them. Finally, because there is no access at ONTs, they are unmanaged and have no local user interface, making them very secure
