Troubleshooting PON networks effectively with carrier-grade ethernet and WDM-PON

WDM-PON for FTTx

Figure 1 illustrates the general FTTx (Fiber-to-the-x) architecture using a WDM-PON (Wavelength Division Multiplexed Passive Optical Network). As can be seen in the figure, this general-purpose architecture can serve multiple applications for both the business and residential customer. This functionality is possible since each end point is connected to the central office through a dedicated bid...

Design and Implementation of WDM-PON Solutions

Review on Next Generation WDM-PON Technologies

We presented review on current advancement in WDM-PON technologies to standarized economical system implementation, and also discuss cost-effective solutions and potential areas of application. Key-Words: WDM-PON, OFDM, OCDMA, RSOA.

MIMO-OFDM WDM PON with DM-VCSEL for femtocells application.

We report on experimental demonstration of 2x2 MIMO-OFDM 5.6-GHz radio over fiber signaling over 20 km WDM-PON with directly modulated (DM) VCSELs for femtocells application. MIMO-OFDM algorithms effectively compensate for impairments in the wireless link. Error-free signal demodulation of 64 subcarrier 4-QAM signals modulated at 198.5 Mb/s net data rate is achieved after fiber and 2 m indoor w...

Simple carrier-phase estimator for high-speed RSOA-based coherent WDM PON.

It has been recently reported that reflective semiconductor optical amplifiers (RSOAs) can be used as phase modulators for the cost-effective implementation of the high-speed wavelength-division-multiplexed passive optical networks (WDM PONs). For the detection of the phase-shift-keying (PSK) signal generated by using an RSOA, we should be able to estimate its carrier phase accurately at the di...
