abstract: The colorless technology has been offered as a solution to decrease the cost in wavelength division multiplexed passive optical network (WDM PON) The self seeded reflective semiconductor optical amplifier (SS RSOA) based on WDM PON has been proved to be a promising solution among colorless operations. In this paper, the principles, transmission limitations, and recent research of SS RSOA based on the WDM PON technology are reviewed. This paper aims to provide a broad perspective on the status of the SS RSOA technology to researchers and application engineers who work with solutions in colorless operations. A list of more than 60 research publications on the subject has also been appended for a quick reference.

abstract: The continuously increasing bandwidth demand of information and communication technology (ICT) is leading a rapid evolution towards next generation passive optical networks (NG PON) However, the power consumed at the access network is experiencing a tremendous growth due to the employment of the Optical Network Units (ONU) For energy conservation in this PON, watchful sleep mode is the newest standardized mechanism that simplifies the features of both cyclic sleep and doze modes to provide higher energy savings. To exploits its functionality, this sleep mode with a dynamic bandwidth assignment (DBA) scheme is a promising solution. Therefore, this study presents the performance of watchful sleep mode in a 10 GB capable PON (XG PON) network employing the Immediate Allocation with Colorless Grant (IACG) DBA. This study firstly review the current progress of the power saving techniques in XG PON. Our simulation results show a better performances compared to the standard in term of upstream (US) and downstream (DS) delays. We also achieve 41 of energy savings at 0.47 network load.

abstract: single fiber WDM PONs based on reflective semiconductor optical amplifier(RSOA)has become widely accepted In the schemes of colorless WDM PONs,but its performance have larger decline because of the Rayleigh scatting efficiency when along the optical fiber teansmission.The paper discusses how to eliminate the effects of Rayleigh scattering in WDM PON.First,the colorless WDM PON is introduced,and a description of the mechanism of the Rayleigh scattering is given.The paper then makes a review of methods of eliminating Rayleigh scattering effect,and describes three schemes of them in details.Finally,software Optisystem is used to demonstrate how to emulate the Rayleigh scattering effect in a new ring structure of WDM PON.

abstract: We review our recent research activities on the applications and technical issues of WDM passive optical networks (WDM PONs) First, we describe our focus on two candidate applications of WDM PON: one is a long reach WDM PON based on wavelength routing for metro access integration, and the other is a short reach WDM PON for coexistence with current PON systems. We identify that the realization of colorless optical network units (ONUs) is an important technical issue for both applications, and an effective protection function is another important issue, especially for the long reach WDM PON. We compare several colorless ONU approaches as well as introduce our recent research results to resolve the issues raised by some colorless ONU approaches. We also describe two demonstrations: one is the long reach WDM PON with a wavelength shifted protection scheme as well as loop back type colorless ONUs, and the other is a WDM PON coexisting with a current PON system with tunable type colorless ONUs.

abstract: We review space division multiplexing passive optical networks (SDM PONs) based on multi core fibers (MCFs) and few mode fibers (FMFs) We compare and analyze the characteristics in terms of MCFs and FMFs used in PONs. A scheme of MCF based SDM PON with colorless ONUs without any signal processing technology is demonstrated, thereby achieving a low cost and making the system design much easier.

abstract: Wavelength division multiplexed passive optical network (WDM PON) has long been considered as an ultimate solution for the future optical access network capable of providing practically unlimited bandwidth to each subscriber. On the other hand, it is still considered to be too expensive for the massive deployment. To solve this problem and meet the ever increasing demand for bandwidth, there have been numerous efforts to improve the competitiveness of WDM PON. This chapter reviews the current status and future direction of these WDM PON technologies. We first review various colorless light sources, which are critical for the cost effective implementation of the optical network units (ONUs) and several representative network architectures proposed for WDM PONs. We then review the recent research activities for the realization of high speed >10 Gb/s) and long reach WDM PONs. Various fault monitoring and protection techniques are also reviewed as they can be increasingly important in the future high capacity WDM PONs.

abstract: The self seeding of reflective semiconductor optical amplifiers (RSOAs) was proposed to achieve colorless operation in optical network units (ONUs) of wavelength division multiplexed passive optical networks (WDM PONs) With the self seeding technique, the use of external optical seeding sources and temperature tracking to maintain wavelength alignment, are not required in the seeding of these devices. This paper provides a review of the self seeding technique, outlining the benefits and drawbacks in the context of WDM PON deployment. A review of recent experimental WDM PON demonstrations based on self seeded RSOAs as colorless ONUs, is also presented. The use of additional techniques and components in these demonstrations to alleviate some of the drawbacks of the self seeding technique, is highlighted.

abstract: In this paper we review our recent works on low cost lasers and remote modulators for Optical Network Unit in access network. Our work is carried out in the context of an FTTH PON migration scenario towards 10Gbit/s base rate as well as towards more capacity and flexibility using WDM technology. All components are based on the attractive thermal, gain and absorption properties of AlGaInAs/InP material system. As a first step to the speed increase we propose a new uncooled 10Gb/s laser based on a self thermal compensation principle. As a next step, new WDM PON architectures will require wavelength agnostic component for ONU. For this purpose, we demonstrate new colorless concepts on 10Gb/s remote amplified electro absorption modulators. We show low cost FTTH components may also be attractive for emerging access metro WDM technology introducing colorless principle in reconfigurable add and drop multiplexers
