| Wireless networks have become ubiquitous in the past few years in commercial as well as military applications. Inevitably scenarios arise where, because of geographic concerns or temporary deployment, optical transport can be utilized to back haul wireless traffic in its native RF format. Optical transport of this type presents its own engineering challenges and modeling can assist in predicting the performance as well as guiding the overall design of the system. Modeling of such systems should include fiber impairments, transceiver characteristics as well as interactions with other signals being transported in the same medium.
Modeling of the transport of CDMA, UMTS, WiMax, WiFi and Bluetooth in an optical network will be discussed. Examples of wireless transport approaches and problems that arise such as the degradation of Tx/Rx isolation due to Rayleigh scattering in bidirectional links will be presented. In this paper, the challenges in networks with multiple wavelengths (DWDM and CWDM) in addition to frequency division multiplexed approaches will be addressed. The value and techniques of system modeling in this type of transport will be presented along with a few illustrative examples
