How to Design a Highly Reliable Fiber Optic Network

What would happen if a fiber optic or cable is cut in a large Hubbing place is destroyed in a fibre optic network? If the entire system put in?
This is the subject of this article: the survivability of a well networked in fiberglass.

modern fiber optic transport systems have enormous capacity for voice applications, video - and data traffic. At the same time, the fibre network should be designed to take full advantage of these economies of scale during minimize maintenance costs. The main design objective is to take advantage interoffice expensive (between buildings) to maximize the number of circuits remains intact after a Worst-Case failure while reducing maintenance costs underway, with this survivability.

Conventional (existing) Networks of architecture and design methods and future technologies can also be used to achieve this goal, to some degree to another.
The principles of designing a network of fiber optic survive. In other words, the basic principle behind the design of effective management of networks Fibre optic is the "demand aggregation." Use demand aggregation investment Hubbing Facility hierarchies and optimize network investment.

What is Facility Hubbing?

Facility Hubbing depends on the fact that the fiber optic equipment makes most of the costs in a fiber optic network. A network of fiber-optic total cost is not very sensitive on the network. At the same time, fiber is capable of many buildings for building traffic. Accordingly, it is concluded that traffic routing of each building in a building selected, given that its "hub" is the most efficient network design.

In this way, traffic aggregate Bundle possible use of technology fiberglass.
On the course, all traffic is sorted and attributed to their destination. Digital Cross-Connect (DCS) is used for the hub to reorganize the declining rate of traffic in a higher rate of traffic. Thus, all traffic is concentrated at high capacity for a central location, where applications are sorted according to their destination.

What Facility hierarchy?
Facilty hierarchy is the extension of the installation Hubbing. The concept of the installation Hubbing placed a little further.
In this concept, the buildings are in "clusters", where each cluster, a hub of the building. This concept considers such factors as the Community interest and geographic area.

Clusters can be grouped into "sectors", with each segment of a "bridge". The bridge is actually a race called upon to manage buildings Inter-cluster transport demand. A bridge can then total demand cluster from several hubs in a great need to be routed to another bridge in the same way that aggregate demand is at a hub or a building.

Indeed, the notion of hierarchy of the structure may be extended by any number of levels.

Conclusion

fiber optic current technology trends have forced a radical change in the structure of networks and the nature and the way networks are designed. The vast capacity of fiber optic systems have led to what powerful networks with large concentrations request in a few facilities.
properly designed network architecture can increase the costs of network easy, but the increase network capacity very survival.
