We demonstrate experimentally 4 × 10 Gbps wavelength division multiplexing repeaterless transmission system using non-return-to-zero differential phase-shift keying modulation format over 300-km standard single-mode fiber. The channels used were 1546.9, 1547.7, 1548.51 and 1549.2 nm with 100 GHz spacing. In this system design, a dispersion compensation module is used; multi-channel-chirped fiber Bragg...

We present analysis of different modulation formats using actual Polarization Mode Dispersion (PMD) data of deployed fiber links in the metro area in Kuala Lumpur, Malaysia. Simulations have been conducted for comparing the performance of Non-Return-to-Zero (NRZ), Return-to-Zero (RZ), Carrier-Suppressed Return-to-Zero (CSRZ), Phase Shaped Binary Transmission (PSBT) and Differential Quadrature Phase...
We investigated experimentally the performance difference between using Multi-Channel Chirped Fiber Bragg Grating (MC-CFBG) as dispersion compensators in the pre-compensation and post-compensation configuration for a long-span optical transmission system. The transmission medium consists exclusively of a single type of fiber, the standard single mode fiber (SSMF), G.652. The experiment was conducted...

This paper presents current implementation of Fiber-To-The-School (FTTSchool) solution as the last mile access technology to the schools. The deployment of FTTSchool at 25 schools in Putrajaya and Cyberjaya area remarks the beginning of a high-speed broadband service to the school. This paper covers the migration of the access network medium from copper to fiber optic based networks, which is an emerging...

This paper presents a dynamic Routing and Wavelength Assignment (RWA) for a Dense Wavelength Division Multiplexed (DWDM) network under the wavelenght continuity constraint using ant colony optimization (ACO). Simulations are run to compare the performance of ACO-based dynamic RWA (ADR) with the common static RWA on a mesh network.
This paper presents wavelength conversion based-on degenerate four-wave mixing (DFWM) assisted by Raman ring laser (RRL) in the distance of 3 km of highly nonlinear fiber (HNLF). By using a single external lightsource which functioning as a signal source, the effect of wavelength conversion at different FBG in RRL can be seen.
In this paper, authors compared the performance of the MPOS routing algorithm against conventional packet schemes using multimedia traffic. The MPOS routing segregates the different types of multimedia traffic into dedicated classes/priorities and assigns a light path for each of them. Improved network performance has been observed by the MPOS technique at high traffic load.
This work presents a novel routing protocol based MPOS (B.H.L. Lee et al., 2006), which is used in the construction of the multiprotocol switch for multimedia traffic. The MPOS routing segregates the different types of multimedia traffic into dedicated classes/priorities and assigns a light path for each of them. Experimental results of the MPOS routing optimize cost of the maximum end-to-end delay...
We presents an incoherent optical spectral CDMA (OS-CDMA) multiple-access system that uses in-fibre Bragg gratings for encoding/decoding. Our measurements verify that this technique suffers from severe chromatic dispersion. Nevertheless with appropriate dispersion compensation, the system is able to achieve a span of 100km.
This paper instigate a design for optical packet switching using all optical wavelength conversion using cross gain modulation (XGM) in DWDM network. It integrate an arrayed waveguide grating (AWG) as its core switching matrix to manage packet switch traffic within the optical network. The packet switch has the capability to switch optical packet traffic through the AWG at a 10 Gbps with multicasting...
