RF Overlay

Video in GPON & Active Ethernet Networks


The days of good old linear TV are far from being numbered. On the contrary, over the last years TV viewing time in private households has even further increased from an already high level. However, how and especially where viewers use their TV is changing. Due to Video-on-Demand, multiscreen, SmartTV, and HbbTV, viewing habits and needs change from generation to generation.

As a rule, TV becomes more interactive and mobile the younger the viewer is. At the same time there is a trend towards HD technology, and as a consequence, bandwidth requirements are rapidly increasing. Telecommunications service providers and city carriers have to take this development into account when expanding their existing network infrastructure.


The Optopus Platform

Economically efficient expansion strategies are needed. For mere distribution services, such as TV, a point-to-multiple-point solution such as RF Overlay is advisable. In this solution, all analog and digital TV channels are transmitted to the customer via an additional wavelength (1550nm) or through a dedicated fibre. With its high-capacity optical platform Optopus, WISI offers system operators a technically mature solution for the realisation of optical TV distribution in FTTx networks. The platform includes a wide range of 1550 nm transmitters, as well as powerful EDFAs whose capacity vary with the dimension and topology of the respective network - thereby providing system operators with an ideal solution which is equally efficient and sustainable.
