Abstract

This paper presents state-of-the-art trial equipment in a fiber-oriented wireless access system. This equipment can deal with a maximum of seven traffic channels in a cell using two carriers with a four-channel TDMA access format. Signal extraction and frequency arrangement (SEFA) technology is highlighted to show that it facilitates optical link non-linearity and increases the CNR. This results in improving the input dynamic range. The overall system performance is also presented in a worst case scenario with an optical loss of 15 dB. It is shown that the receiver sensitivity of 10 dBμV and the receiver intermodulation performance of 47 dB are obtained using a π/4-QPSK signal with a transmission rate of 384 kb/s. The use of SEFA will make possible cost effective FP-LD implementation into a fiber-oriented wireless access systems
