ABSTRACT
Growing demand for high speed internet is the primary driver for the new access technologies which enable experiencing true broadband.single splitting is used to provide triple play services-voice, data, and video using single fiber.but it cannot satisfy the increasing customer demands.a new technology named double splitting with increased customer accessibility can be employed to meet the demands.
In this project, the link length and bandwidth optimization of GEPON fiber optic link is done with two bidirectional splitters, so as to enhance the band width demand arising out of various demand clusters. The design and optimization of this network is done using Passive optical splitters and BWDM technique, which result in increased number of bandwidth provisioning and link length enhancement.
There are mainly two combinations of 1x4 and 1x8 bidirectional splitters, ie., 1x4 to 1x8 splitter and 1x8 to 1x4 splitter combinations.our optimization link design gives the optimal distance of two combination and high bandwidth data transfer with less power loss and minimal error occurrence.this technology reduces the initial cost which enhance the growth of communication networks.
In this project we propose a highly efficient network that ensures a reliability and cost effectiveness. It also allows the service providers to provide increased number of triple play services, from a single point effectively, as there is huge bandwidth demand. The same thing can be expanded for future by implementing a combination of 1x16 and 1x32 splitters in short haul communication links.
FIBRE TO THE HOME
FTTH offers triple play services with data speeds ranging from 155 Mbps to 2.5Gbps Downstream (Network to User) and 155 Mbps to 1Gbps Up stream (User to Network) range of services due to high bandwidth and Though the field trials and technology development for fiber in the access loop started in late 1980s, real deployments did not happen as the deployment costs were very high at that time. In the last 20 years enormous progress is made in optical networking equipment and production of high quality optical fibers associated with falling prices are driving forces for fiber to the home(FTTH).
FTTH ARCHITECTURE
Active and passive are two commonly used FTTH architectures for FTTH deployment. Active Architecture is also called as Point 2 Point(P2P) and Passive Optical Network (PON) architecture is called Point to Multi Point(P2M). Choice of active or passive architectures for deployment depends on the type of services to be delivered, cost of the infrastructure, current infrastructure and future plans for migrating to new technology. ACTIVE Technology Active Ethernet also called Ethernet Switched Optical Network (ESON) or Point to Point(P2P) Network architecture provides a dedicated fiber to the side from the central office exchange.A P2P architecture is a very simple network design. Since the fiber is dedicated, Operation, administration and maintenance of the content and trouble shooting become easy. Active FTTH solutions are implemented in many different ways, through both standard and proprietary methods. Since the distances of the central node and remote sites are known, estimation of power budget, trouble shooting the faults in the network would be easier. Transmission in P2P configuration, is more secure, since all transmissions are physically separated by fiber. Only the end points will transmit and receive information, which is not mixed with that of any other customer.
