Hello and welcome to this training course on Principles of Communications Cabling.
We live in the age of data. Big Data
What is Big Data?
Big data is the set of technologies created to store, analyse and manage the explosion of data available to us.
This explosion in available data is caused by the rapidly increasing number of devices (estimated to be over 20 million) now connecting to the internet.
These devices are in very diverse sectors such as medicine, agriculture, gambling, engineering and environmental protection.
Smart sensors in medical devices monitor patient vitals and provide important medical information.
Vehicles and appliances have increasing number of data sensors that can tie into automation or artificial intelligence for optimal control.
In agriculture, soil and weather monitoring can be used to identify the time to sow and harvest and predict the exact amount of fertiliser or pesticide application.
In Industry Information 4.0 and the Internet of things we now see more autonomous manufacture with a high degree of machine data interchange, robotic operation and data interchange among different computer systems.
The increase in demand for data and the need to use the data very quickly requires the transfer of data in communications cables at high speed.
“High-speed” is a relative term that has constantly evolved from a few hundred bits per second to communications channels that feature transfer rates over 100Gbits per second.
The communication signal must also ensure that the data transferred has a high degree of integrity with minimal signal loss and distortion.
This critical requirement to transfer large volumes of data in high- speed signals has led to the roll out of new high capacity communications cable networks.
In this course we will look at the principles of communications cable networks and how they work.
