Maximizing Optical Power Throughput in Long Fiber Optic Links

A Quick Pre-Deployment Fibre Optic Link Design Methodology based on Q-factor in a Digital Eye

Fibre optic cables have become the main driving force behind high data throughput infrastructure. In modern wideband communication systems, they are deployed as backbone cables in many long haul links as well as links to clients (Fibre to home). Several Gigabits per second data rates have become common. Field engineers need to have a thorough knowledge of physics behind any physical component u...

High-stability transfer of an optical frequency over long fiber-optic links

We present theoretical predictions and experimental measurements for the achievable phase noise, timing jitter, and frequency stability in the coherent transport of an optical frequency over a fiber-optic link. Both technical and fundamental limitations to the coherent transfer are discussed. Measurements of the coherent transfer of an optical carrier over links ranging from 38 to 251 km demons...

Backhaul-Aware Decoupled Uplink and Downlink User Association, Subcarrier Allocation, and Power Control in FiWi HetNets

Decoupling the uplink and downlink user association improves the throughput of heterogeneous networks (HetNets) and balances the traffic load of macro- and small- base stations. Recently, fiber-wireless HetNets (FiWi-HetNets) have been considered as viable solutions for access networks. To improve the accuracy of user association and resource allocation algorithms in FiWi-HetNets, the capacity ...

Terrestrial Coherent Free-Space Optical Communication Systems

In the past three decades, the demand for high-speed communications has increased dramatically, while fiber optical communications has been applied in the majority of data transmission networks. Optical fiber has advantages over existing copper wire in long distance and high demand applications. The ever increasing need for higher bandwidth and higher speed optical data and communications trans...
