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...

Fault Location for Wdm-pon Using a Multiple-longitudinal- Mode Laser Modulated by Chaotic Wave

We experimentally demonstrate a cost-effective method to locate faults in wavelength-division-multiplexing passive optical network (WDM-PON) utilizing a multiple-longitudinal-mode Fabry–Perot semiconductor laser directly modulated by chaotic wave from a Colpitts oscillator. Due to chaos modulation, every longitudinal mode of the laser has chaotic intensity waveform. Using a tunable optical filt...

Gbit-Class Transmission Using SOA Data Rewriter for WDM-PON

We describe the transmission characteristics of a wavelength independent wavelength division multiplexing passive optical network (WDM-PON) based on a wavelength channel data rewriter (WCDR). The WCDR is composed of a linear amplifier (LA) and a saturated semiconductor optical amplifier (SOA), and by using the WCDR in optical network units (ONUs), we can erase the downstream signal and modulate...
