Modulation and Demodulation
Modulation Modulation is the process of changing one or more properties of the carrier signal in proportion with the information signal. In modulation, some parameter of the carrier wave (such as amplitude, frequency or phase ) is varied in accordance with the modulating signal . This modulated signal is then transmitted by the transmitter Demodulation… -
SONET Synchronous Optical Network
SONET Synchronous Optical Network Multiplex electrical signals (Digital) from different sources and creates optical carrier (OC). USA, CANADA and JAPAN developed T1 Standard. ANSI develop SONET. The rest of the world uses a primary rate of E1. ITU-T develop SDH. Topics What is SONET? What is Synchronous Digital Hierarchy? What is SDH? What…

Transmission Modes
The way in which data is transmitted from one device to another device is known as transmission mode.
Telecom Standards
Standards are essential in creating and maintaining an open and competitive market for equipment manufacturers and in guaranteeing national and international interoperability of data and telecommunications technology and processes.
Characteristics Of Data Communication System
The effectiveness of a data communications system depends on some fundamental factors: delivery, accuracy, Timeliness, Jitter, Error detection & Correction.
Components of Data Communication
Data communication is the exchange of information/data between two devices by using some transmission medium such as a cable or air.
Optical power budget and Link loss
Link power budget calculation is used to ensure that power reach at the receiver end is greater than average power required by the receiver.
Optical fiber Losses
We have already discussed Optical fiber, Power meter and OTDR in our previous videos. Today we will focus on fiber losses only. Fiber Optic Comm Fiber optic cable is lighter, smaller and flexible than copper cable. It can transmit…
