Researchers break fibre optic throughput record

Researchers break fibre optic throughput record

Japanese researchers at NIICT have succeeded in transferring data at a rate of 319 terabits per second over more than 3 km. More importantly, their technology is compatible with modern fibre optic networks.

 

However, this performance is not dependent on a revolutionary new material; it is based on the same fibre optic technology already present in our infrastructure. Instead of using a single fibre channel, the research team relied on a technique called wavelength-division multiplexing, or WMD.

The idea is based on a combination of several fibre optic 'cores'. This means that the signal can be distributed to different bands at the same time. This avoids having a single fibre carry the entire load, which in particular generates interference.

 

To achieve this record speed, the Japanese researchers used an optical fibre with four 'cores', and made use of a third 'highway' for the signal; in addition to the two usually used in this type of application, they also used the S-band. They also subjected the signal to two new types of amplification, before undergoing the normal amplification process.

 

What makes this work so disturbing is its practical feasibility. The outer diameter of the team's proposed fibres is exactly the same as that of a standard fibre optic cable. This has a major implication. In order to switch from current networks to this type of technology, there would be no need to replace the entire infrastructure; the new one is already compatible with the old one.

 

Of course, there are technologies that can go much higher, but this technology is only usable in niche cases. The NIICT technology, on the other hand, is directly applicable to the current network.

For the researchers, this very important feature "demonstrates the potential of standard compatibility fibres in the short-term implementation of very high speed fibre networks". Incredible as it may seem, the speeds to which we have access today may seem ridiculous much sooner than we think!

Operators: French complaints increased in 2020

Operators: French complaints increased in 2020

With more than 33,000 consumer alerts via the "J alerte l'Arcep" platform in 2020, the telecoms regulator reveals a 37.5% increase in complaints compared to 2019.

 

Among the 4 operators (Orange, SFR, Bouygues Telecom and Free), the worst performer was Free, generating the most negative requests from the French. It thus takes the place of SFR. In detail, Bouygues Telecom had 19 alerts per 100,000 customers. This compares to 25 for Orange, 26 for SFR and 29 for Free.

 

The French have used the Internet much more in 2020, with the various confinements, and have noticed many problems. "This year again, the most frequent complaints received concern the quality of service, including after-sales service. Next comes dissatisfaction with network developments (fibre rollout, insufficient mobile coverage, etc.), in particular fibre rollout, followed by operators' commercial practices and difficulties encountered when changing operators", explains Arcep.

 

Generally speaking, French people's satisfaction has fallen. If the average for operators was 7.65/10 in 2019, it was 7.5/10 in 2020.

The biggest differences are in fixed-line services. SFR customers give SFR a satisfaction rating of 6.8/10 compared to 7.5/10 for Orange.

For mobile, the scores range from 7.4 for SFR to 7.8 for Orange and Free.

While the operators' customer services are generally poorly rated. Free does well with a 2.6/5, while SFR closes the bench with a pitiful 1.8/5.

Free challenges Orange with an offer for professionals

Free challenges Orange with an offer for professionals

On March 23th, Free announced its commercial offers for businesses: Free Pro. This offer is aimed at very small businesses, SMEs, but also local authorities and individual entrepreneurs who do not have the resources to buy services from competitors.

 

Free Pro will provide professionals with a 100% fiber-optic 10 EPON Freebox, featuring tri-band WiFi combined with a repeater. In order to guarantee an Internet connection even in the event of a power cut, this box has an external 4G modem and is based on both Free's fiber network and that of Jaguar Network. It also has a NAS function that allows you to save up to 200 GB of data in the cloud, WiFi 5 and standard WPA3 protection.

 

Free hopes to make a difference thanks to the supposed reliability of its hardware: the box is equipped with a dedicated OS that is capable of self-diagnosis thanks to AI. The operator also pledges to provide online assistance within eight hours with dedicated support based in France. The offer includes two fixed lines, with unlimited calls to mobiles in France and in more than 100 destinations around the world, as well as an unlimited 4G/5G mobile package.

 

The operator is also taking the opportunity to launch a mobile offer for professionals, which is not really different from its general public offer. For €19.99/month, you get 150 GB of 4G/5G data, 25 GB of roaming from more than 70 destinations and unlimited calls to mobiles and landlines to more than 100 international destinations. The subtlety is its customer service dedicated to professionals, accessible 7 days a week from 7am to 8pm, with a commitment to obtain a response within eight hours.

A toll for Internet giants

on Wednesday, 29 May 2019 Posted in Archives Rezopole, Archives GrenoblIX, Archives LyonIX

A toll for Internet giants

France's leading Internet service providers ranked it as one of the largest consumers of bandwidth a year ago. These groups, such as Google, Netflix, Akamai, Facebook, take advantage of the tips of French operators without paying their fair share.

The French Telecoms Federation (FFT) and its president are therefore calling for "more equity". In an interview with Le Figaro, Arthur Dreyfuss explains that "80% of the taxes paid in France by digital players are paid by French telecom operators. At certain times of the day, 80% of telecom network traffic is due to YouTube, Netflix, Amazon and Facebook".

Under these conditions, the FFT proposes to introduce a toll, i.e. to charge for access to the networks of French operators. As these pipes are extremely profitable for American giants, access providers are wondering when they will participate in financing the infrastructure. Indeed, ISPs must constantly invest in expanding and improving their networks. These are therefore heavy financing for which the Internet giants participate little or not at all.

This proposal does not come about by chance since the government wants to introduce a tax on the advertising activities of the largest digital companies. It should be implemented very quickly since it has just been voted by the Senate.
