Comparison of optical millimetre-wave system conceptswith regardto chromatic dispersion

An Analytical Solution for Fiber Optic Links with Photonic-Assisted Millimeter Wave Upconversion Due to MZM Nonlinearities

“…Plugging (16) in the wave equation and using the expanded phase factor β(ω), given by (15), first order perturbation theory leads to [15]:…”

“…This is null when argument is a π⁄2 odd multiple [16]. Therefore, when a signal with frequency is launched into a fiber optic link, the fundamental electric power component will ideally vanish at a first distance 1 = 2 0 2 2 and then at each distance interval Δ = 0 2 2 .…”

Transmission Performance of mm-Waves on Radio over Fiber Systems: Dispersion and Intermodulation Issues

“…The electrical mm-wave signal is filtered, amplified and directly delivered to the BS antenna. This approach has the advantage of a simplified BS design but it is susceptible to fiber chromatic dispersion that severely limits the transmission distance [4]. For this reason the architecture considered here employs OSSB modulation.…”

“…The scenario on the Wireless Wide Area Networks (WWAN) connections is even worst, with theoretical maximum speeds of 14. 4 Mbps with current High-Speed Packet Access (HSPA). The next generation technologies provide 42Mbps in HSPA+ and 100Mbps with Long Term Evolution (LTE).…”

Calculation of Receiver Sensitivities in (Orthogonal) Subcarrier Multiplexing Microwave-Optical Links

“…However, standard modulation of an optical carrier produces a double sideband (DSB) spectrum. Due to dispersion, associated subcarriers suffer a different delay in the upper and the lower sidebands, which translates into dispersive fading after photo-detection [8]. Consequently, optical single side band (SSB) modulation is preferred as it eliminates dispersive fading [9] and achieves the higher tolerance to dispersion expected from SCM.…”
