Four evolutionary stage of optical network

Future trends optical networking should be further enhanced by network intelligence and automation to ensure a more accurate resource data, fault location more quickly and reduce the costs of maintenance personnel, thus achieving the purpose of reducing OPEX. Based on the current technical studies of the evolution of the optical fiber network should go through four stages.

Port intelligent. Automated data acquisition via fiber ports visualization and data to achieve more accurate optical network resources, the process is more optimized. Including electronic work order closed-loop operation, the port information is automatically collected and guidance of field operations and so on. This technique has started from 2011, it is also already gradually applied in the bearer network and access network outside of the fiber.

Link intelligent. Through centralized remote fiber test and performance data analysis, to achieve fast fault location, in order to protect the normal operation of fiber optic networks. Including analysis and other online OTDR monitoring to establish the link test, optical performance and network fault early warning mechanism for content, this technology research from 2014, there are some small-scale applications.

Node intelligent. The concept of intelligent peripherals to expand optical wiring nodes, thus completing the process from the point to the surface, and process optimization intelligent fiber optic network as a whole. Including environmental monitoring passive node has permission to manage passive electronic lock, you can trace the route covers the management of fiber optic lighting and fiber content on the route. This technology is expected to start in 2016.

Reconfigurable networks. The ultimate status of the fiber-based network should be an unmaintained network, automation technology will be fully applied in the fiber-based networks. Including user resources automatically assigned, remote device Automatic defibrillators, automatic routing failure repair. Fiber-based value-added features while sensing characteristics will emerge, such as energy, oil pipeline monitoring, electronic security fence program, based on optical fiber vibration of ammunition safety monitoring. At this time the fiber has not limited communication capabilities, but provides more room for imagination as other industry applications. This technology is expected to gradually start from 2018.
