Two different CS-SSB modulators based on Mach-Zehnder structure used in carrier-distributed long-reach passive optical networks are investigated and compared. The Rayleigh-backscattering beat noise tolerance and transmission performance are also discussed.
We demonstrate using single-sideband-carrier-suppressed (SSB-CS) signal to suppress the Rayleigh-Backscattering (RB) in a carrier-distributed PON. The SSB signal is generated by a dual-parallel Mach-Zehnder modulator (DP-MZM). The split-ratio and reach are also investigated and analyzed.
We demonstrate an optical wired and wireless access network using wavelength-splitting (WS) at remote-node. A pair of CW carriers is generated from each laser source for wired and wireless applications respectively for effective Rayleigh-backscattering mitigation.
We propose an all optical wavelength converter using a multi-longitudinal-mode Fabry-Perot laser diode without any external probe beam or external build-in cavity. The proposed converter apparatus is simple and cost-effective for WDM network applications.
In this letter, we propose and demonstrate a signal- remodulated wired/wireless network using reflective semiconductor optical amplifier as a colorless modulator in the optical networking unit/remote antenna unit. Dark return-to-zero and binary phase-shift-keying signals are used for the downstream wired and wireless broadcast, respectively. The downstream signal will be remodulated to produce the...
We demonstrate a bidirectional ROF system using a separate optical-clock distribution to mitigate signal-fading and code time-shifting. Error-free signal remodulation using downlink DPSK and uplink OOK was achieved in a 20-km reach ROF system.
This work characterizes how the bandwidths of transmitter, receiver and optical filter affecting the quality of optical dark-return-to-zero (DRZ) signal. Optimum filtering bandwidths at back-to-back (B2B) and 80 km single mode fiber transmission are analyzed.
