The Synchronous optical network, commonly known as SONET, is a standard for communicating digital information using lasers or light emitting diodes (LEDs) over optical fiber as defined by GR-253-CORE from Telcordia. It was developed to replace the PDH system for transporting large amounts of telephone and data traffic and to allow for interoperability between equipment from different vendors.

The more recent Synchronous Digital Hierarchy (SDH) standard developed by ITU (G.707 and its extension G.708) is built on experience in the development ....etc

Abstract
This paper explains about SONET Synchronous Digital Network, that has been greeted with unparalleled enthusiasm throughout the world. It also explains how it came into existence and in which way it differs from others. What does synchronous mean? Bits from one telephone call are always in the same location inside a digital transmission frame .
This material is assumed to be comfortable to the reader as the basic concepts of a public telecommunications network, with its separate functions of transmiss ....etc

Optical Networking Technology


Who needs more bandwidth?
Increased bandwidth demand will arise from a proliferation of applications such as data and call centers, as well as by the bootstrapping effect of increased consumption resulting from lower rates. For example, if the STD charges are reduced to one tenth of what they are today, I still do not expect to see my phone bill go down because my wife s phone calls will just become ten times longer

1. Define a fiber optic system.
Fiber optic system consists of a fiber optic cable, a light source and a light detector. The
optic fiber is used to carry the light beam from one place to another.
2. What are the uses of optical fibers?
a) To transmit the information of telephone communication, computer data, etc.
which are in the form of coded light signals
b) To transmit the optical images (Example : Endoscopy)
c) To act as a light source at the inaccessible places.
d) To act as sensors to do mechanical, electrical and magnetic measure ....etc

optical code-division multiplexed (OCDM)-based photonic layer security (PLS) system for very high data rate systems, where electronic encryption becomes increasingly expensive and difficult.

Encryption OCDM-based PLS system, which is aimed at emerging 100 Gbps fiber networks, is accomplished by coding and scrambling the optical signal in such a way that the bits cannot be recovered nor be recorded for subsequent decryption. Telcordia has devised novel coding schemes and a compact, programmable coder, working with industry and university pa ....etc
