Growth in the use of devices with Internet access and migration of telecommunications to IP technology have made the bandwidth demanded by users appear for the first time in a long time a limited resource. Optical fiber is demonstrating to be the solution to this issue based on the capability to provide enough bandwidth to manage large volumes of data at high speed featuring low loss transmission. Passive optical networks PON are presented as an alternative with respect to conventional copper-based access networks due to the use of distribution passive elements, which have a lower maintenance cost as compared to its active counterpart.

Topics include a discussion of the noise sources in the system, dynamic range, and a characterization of the distributed feedback fiber laser source noise. We show the crosstalk levels in the experimental arrangement to be between and dB depending on the mechanism involved.
Printable Version. TDM combines multiple digital signals into a single serial digital bit stream. A specialized circuit, called a serializer, allocates parallel input streams into time slots in the serial output. In a fiber optic system, the serial bit stream is transmitted as a single wavelength down a fiber optic cable. On the far end of the channel, a deserializer reconstructs the original parallel signal from the serial bit stream as shown in Figure 1. The serial data rate must be sufficiently fast to ensure no data is lost. Fiber optic transmitters and receivers for high resolution AV signals typically operate at a 4 to 6 Gbps data rate.

So in order to analyze the system performance based on various parameters i. BER and Eye pattern. The proposed dual scheduler will also be used in the same optical networks. We extend the existing MCDRR scheduling algorithm for n channels to the case of considering two schedulers for the same n channels.
An ultra-high bit-rate fiber optic hybrid system is proposed in this work. The proposed system utilizes the advantages of both wavelength division and time division multiplexing techniques. MDRZ format is proved to be the best among all. The proposed system performance has been investigated at various bit rate of 10Gbps, 40Gbps and Gbps, for over the selected transmission lengths of Km, Km, Km respectively. Unable to display preview.
Show all documents The main objective of the multi-channel scheduling is to schedule the transmissions of the data over multiple channels to the users. The important measures in choosing a scheduling algorithm are throughput, latency, fairness, and complexity. The main objective of this paper is to. FTTH provide many services such as peer to peer transmission, video file swapping, internet protocol, video on demand. To fulfill all these demands passive optical networks are required using increase reach, high bandwidth, greater density, security etc. The PON delivers the services by means of different multiplexing techniques.
