All-optical network (AON)

6/2/15  |  Technical Article

In a light-based multiplexing existing communication network, each node in the network to complete the light - electricity - light conversion, still signal processing speed of information exchange, and one of the electronic components in adaptation high-speed, large-capacity needs, problems such as bandwidth limitations, clock skew, crosstalk serious, high-power and other shortcomings, thereby generating a communication network "electronic bottleneck" phenomenon. To solve this problem, it put forward the concept of all-optical network (AON) is. The so-called all-optical network, refers to the entire process of data transmission between the exchange from the source node to the end-user nodes in the optical domain, namely a complete end to end optical path with no electrical intervention.
