Fiber chromatic dispersion effects on multichannel digital millimeter-wave transmission

Abstract
The 28-GHz local multipoint distribution service (LMDS) band will be used to deliver broadband wireless services to many users. Millimeter-wave fiber links provide a low-loss method of distributing the multiple QAM channels to remote antennas from a central control station. Through simulation, this paper examines the effects of chromatic dispersion of standard single-mode fiber on multichannel millimeter-wave transmission at 1550 nm. It is shown that with proper planning broadband multichannel QAM transmission with acceptable CIR levels is possible over distances up to 80 km.
