World’s fastest internet speed from a single optical chip

By on • ( Leave a comment )

A research team has recorded the world’s fastest internet speed from a single optical chip of 44.2 Terabits per second.This technology has the capacity to support the high-speed internet connections of 1.8 million households in Melbourne, Australia, at the same time, and billions across the world during peak periods.
Demonstrations of this magnitude are usually confined to a laboratory. But, for this study, researchers achieved these quick speeds using existing communications infrastructure where they were able to efficiently load-test the network.
 

Bandwidth and Data Rates

By on • ( Leave a comment )

The terms bandwidth and data rates are often used interchangeably, but they are in fact very different if you work in the cabling world. Your internet provider may advertise a bandwidth of 500 megabits per second (Mbps). In that case, they actually mean data rate. In the cabling world, bandwidth is a property of the cable – its ability to transmit a signal that’s intelligible at the far end. Any signal put on a copper or fiber link will degrade as it gets to the far end. This is a result of simple loss, but also more complex factors such as return loss (reflections), and in the case of copper, crosstalk. Vendors design their copper and fiber cabling to be able to deliver these raw signals (bandwidth) at higher rates.
