The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
This is a list of countries by Internet connection speed for average and median data transfer rates for Internet access by end-users. The difference between average and median speeds is the way individual measurements are aggregated.

Cable assembly containing one or more optical fibers that are used to carry light A TOSLINK optical fiber cable with a clear jacket. These cables are used mainly for digital audio connections between devices. A fiber-optic cable, also known as an optical-fiber cable, is an assembly ...
Based on OpenSignal in November 2016, there were only 58.8% of internet users in Indonesia who received 4G LTE signal, and received only HSPA+ signal or lower the rest of the time, ranking Indonesia 51st in the world. The download speed using 4G LTE in Indonesia was only an average of 8.79 Mbit/s (ranked 74th in the world). [3] Based on the ...
In a hybrid fiber-coaxial cable system, television channels are sent from the cable system's distribution facility, the headend, to local communities through optical fiber subscriber lines. At the local community, an optical node translates the signal from a light beam to radio frequency (RF), and sends it over coaxial cable lines for ...
If you're using broadband (cable) internet and you can't connect, try the following troubleshooting steps in the order listed until you get up and running again. 1. Check if you can visit other sites with a different browser - If you can go to another site, the problem may be associated the browser you're using.
Ethernet over fiber is a networking technology that delivers Ethernet bandwidth ranging up to 400 Gbit/s using optical fiber lines. Such wired transmission methods extend connectivity over long distances up to 200 km, support higher bitrates and provide far greater immunity from electromagnetic interference (EMI) than electrical connections.
A terrestrial cable is a communications cable which crosses land, rather than water. Terrestrial cable may be subterranean (buried) or aerial (suspended from poles ), and may be fiber or copper . [ 1 ] [ 2 ] The term "terrestrial cable" is principally used to distinguish it from submarine cable , [ 3 ] although some overlap exists between the two.
