WiMAX is a standard based on wireless technology that provides high throughput broadband connections over long distance. This technology can be used for a number of applications, including “last mile” broadband connections, hotspots and high-speed connectivity for business customers. The objective of this article is to propose an approach to design a network on the latest standard of WiMAX namely...
The use of multi-tone signaling can avoid the high loss of FR4 traces beyond 10 GHz while confining the task of equalization to 2.5-GHz-wide subchannels. This paper presents multi-tone transceiver design issues and derives performance requirements such as linearity, sensitivity, quadrature mismatches, and phase noise. Possible transmitter and receiver implementations are described and a critical interference...
Cross gain modulation between two different optical signals, inserted through separate ports to an active MMI, has been experimentally measured. The observed trend of modulation reduction by increase of modulated signal power matches previous simulation results. An associated XPM is expected and could be optimized to enable using the active MMI in all-optical switching.
