Abstract
A Gigabit Ethernet passive optical network (GE-PON)
The GE-PON includes an optical line terminal (OLT), a plurality of optical couplers, and a plurality of optical network units (ONUs). The OLT sets up an active page link and a standby page link in response to a registration request message received over an optical cable. Each of the ONUs is doubly connected with the OLT via the optical cable and is adapted to transmit the registration request message to the OLT, form the active page link with the OLT via the optical cable if it re ....etc

Ethernet passive optical networks (EPON) are an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (CO) and a customer site. EPONs build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PONs (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.
The communications industry is on the cusp of a revolut ....etc

1.1 THE MOTIVATION FOR PON
One of the most critical decisions for any business involves the purchase of capital equipment. The two important factors which influences this decision are equipment cost and the resulting revenue potential. Service providers face this decision when upgrading existing access networks, and they want to minimize the cost and maximizing the revenue potential. Thus, the most important decision the service provider makes when purchasing network equipment ....etc

Fundamentals of Passive Optical Network – Components & its Variants


Passive Optical Network
•Passive optical elements (splitter, coupler, …) based optical distribution network
•Special form of FTTC or FTTH
•Physical star, but logical bus
•Cost effective technology for distribution services
•No powering of remote electronics
•Eliminates need for conditioned enclosures
•Transparent to signal formats
•Simplifies future upgrades

greenfield PON networks was deployed to minimize the costs. This technique uses an efficient heuristic called the Recursive Association and Relocation Algorithm (RARA) to solve the optimization problem. This algorithm can significantly reduce the PON network deployment costs compared to an
intuitive random-cut sectoring approach. The method of cable conduit sharing is proposed to extend to RARA. The studies and analysis shows that there are saturating trends for the PON deployment costs. three system parameters are used viz. optical spli ....etc

ARE NATURAL FIBER COMPOSITES ENVIRONMENTALLY SUPERIOR TO GLASS FIBER REINFORCED COMPOSITES?
INTRODUCTION:-
• Natural fibers have been used to reinforce materials for
over 3,000 years.
• Many types of natural fibers have been investigated for
use in plastics .including , Flax, hemp, jute, straw,
wood fiber, rice husks,wheat,barley,oats .
• Natural fibers have the advantage that they are
renewable resources and have marketing appeal.
• Natural fibers are increasingly used in automotive a ....etc

Abstract:
A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters utilizing Brewster's angle principles are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) near end users. A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architec ....etc
