We propose and demonstrate a simple self-protecting architecture for WDM PON. The protection time was less than 10 ms, and the power penalty caused by the protection process was negligible.
We propose a short-period dispersion-managed fiber that consisted of conventional single-mode fiber (17 ps/km/nm) and negative dispersion fiber (-15 ps/km/nm). Thus, the average dispersion of the… (More)
We developed an analytical model for the statistics of polarization-dependent gain (PDG) in both copumped and counterpumped fiber Raman amplifiers (FRAs). The validity of this model was confirmed by… (More)
We proposed and demonstrated a bidirectional wavelength-division-multiplexing passive optical network by using spectrum-sliced light-emitting diodes (LEDs) with cyclic arrayed-waveguide gratings… (More)
We propose and demonstrate a simple and cost-effective technique to detect and localize the fiber failures in wavelength-division-multiplexed (WDM) passive optical networks. By reusing the downstream… (More)
We evaluate the effects of the downstream modulation formats (NRZ, IRZ, and Manchester) on the performance of the RSOA-based bidirectional WDM-PON. The results show that, by using Manchester format,… (More)
We demonstrate a WDM passive optical network using spectrum-sliced LED's. This network could accommodate more than 40 subscribers with 622-Mb/s downstream and 155-Mb/s upstream channels.
We propose and demonstrate a simple and cost-effective technique to detect and localize the fiber failures in WDM passive optical networks. By reusing the downstream lasers as WDM light sources for… (More)
We designed and fabricated a quasi single-mode fiber (QSMF) for the cost-effective implementation of broadband access networks. The core diameter of the fabricated QSMF was 20 mum. Using this fiber,… (More)
We investigated the effect of temperature variation on the performance of fiber-based optical phase conjugation (OPC). The efficiency and bandwidth of OPC were degraded significantly by temperature… (More)
