Transmission of multiple wireless standards over a radio-over-fiber network

This paper investigates the optical transmission characteristics of an optical signal as it is modulated by a RF signal in an electro-absorption modulator (EAM). The transmission characteristics of the radio-over-fiber (ROF) system were evaluated at cellular bands of 900MHz, 1.8GHz, 1.9GHz, 2.1GHz and the ISM bands of 2.4GHz and 5.8GHz for wireless local area network (WLAN) and intelligent transport systems (ITS) applications. Error vector magnitude (EVM) and packet error rate (PER) measurements were carried out to evaluate the performance.
