In this paper, we investigate the performance of a spectrum shaping technique for the suppression of image-induced crosstalk during the heterodyne detection of wavelength-swept wavelength-division-multiplexed (WDM) signals. In particular, we focus on

We confirm the tolerance of our proposed wavelength-swept wavelength division multiplexing (WDM) access system to four-wave mixing (FWM) crosstalk induced during fiber transmission. Since wavelength-swept light is employed as the carrier in the propo

Radio On Fiber (ROF) is an optical analog technique for transmitting RF signals. With ROF systems, the base station conflguration is simple and independent of the modulation format and protocol. This advantage means that ROF is expected to become a u

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 satu

In order to economically realize a Gbit/s class downlink using 60-GHz millimeter waves, the authors have previously proposed an optical/electrical two-step heterodyne system, based on the Radio-On-Fiber (ROF) transmission technique, in which millimet

A wavelength-division-multiplexing (WDM) access system can be used in two basic ways: user multiplexing, which assigns a wavelength to each user, and service multiplexing, which assigns a wavelength to each service. In current designs for service mul

Recently, various architectures for future networks have been researched and discussed. In one of these approaches, we assume the deployment of an access network in which wavelength division multiplexing (WDM) and time division multiplexing (TDM) tec

We propose an in-line monitoring technique that uses 650 nm visible light for performing maintenance work on Fiber-to-the-home (FTTH) network quickly without the need for measuring skills or external devices. This technique is characterized by visibl
