FTTx is a access network technology that uses optical fiber directly from the central point to the Home. FTTx offers triple play services voice, video and data.
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 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…
Artificial Intelligence (AI) refers to the simulation of human intelligence in machines that are programmed to think and mimic human actions. It involves the development of computer systems capable of performing tasks that typically require human intelligence. AI systems are…
Bit vs Byte
Decibel (db) The decibel (dB) is a logarithmic ratio used to measure sound level. It is also widely used in electronics, signals and communication. The dB is a logarithmic way of describing a ratio. The ratio may be power, sound…
What is Bit rate What is baud rate Bit rate and baud rate Data encoding
The way in which data is transmitted from one device to another device is known as transmission mode.
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.
The effectiveness of a data communications system depends on some fundamental factors: delivery, accuracy, Timeliness, Jitter, Error detection & Correction.
Data communication is the exchange of information/data between two devices by using some transmission medium such as a cable or air.
Link power budget calculation is used to ensure that power reach at the receiver end is greater than average power required by the receiver.
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…
