Les câbles en fibre optique sont constitués d’une âme et d’une gaine. Quand on parle d’âme, on veut citer la matière qui se trouve au cœur du câble de fibre optique. Il a comme utilité d’assurer le transport du signal optique d’un point à un autre. La gaine quant à elle, a pour fonction d’assurer la couverture de l’âme.
Des revêtements pour la protection des câbles en fibre optique
L’âme qui se trouve au centre des cables fibre optique, peut être en verre ou en plastique. C’est sa taille qui justifie la quantité de lumière ou de données qu’elle est en mesure de transporter. Les types de fibres multimodes qui sont le plus souvent utilisés sont le 50 micromètres, le 62,5 micromètres et le 100 micromètres.
C’est la gaine qui se charge de contenir les ondes lumineuses. En plus d’assurer la couverture de l’âme, elle a aussi pour fonction de faire circuler les données le long du segment de la fibre par la réfraction. La gaine se charge aussi d’assurer la protection de l’âme contre d’éventuels chocs.
Les courbures du câble pouvant conduire à une réduction du signal ou simplement à son endommagement, la gaine se charge de la protection, car étant faite d’un revêtement en plastique qui mesure entre 250 et 900 micromètres d’épaisseur.
L’utilité des fibres de renfort dans un câble en fibre optique
Pour toujours assurer la protection de l’âme, des fibres de renfort sont également contenues dans un câble en fibre optique. En plus d’assurer la protection contre les chocs et les courbatures, les fibres de renfort ont aussi pour utilité de protéger l’âme contre tout écrasement lors de son installation.
Ces fibres peuvent se présenter sous forme de tubes qui sont remplis de gel. Elles peuvent aussi se présenter sous la forme de fibres … Read More

A website needs to have fast load times. In a study, Kissmetrics found that around 47 per cent of users want a web page to load within two seconds. Further, around forty per cent of the users don’t wait for the site to load if it takes more than three seconds. The load time of a web page also impacts the search engine rankings of the website. Hence, if your website is not fast enough, then you might have high abandon rates and lose prospective customers. While there are multiple factors that can affect the speed of your website like videos, images, database, etc., a web host can optimize your website for speed and ensure a supersonic load time.
Since all files required by a website are kept on a web server, a slow web host invariably leads to a slow-loading website. Today, we are going to look at Cloud Hosted websites and the reasons behind them having fast load times.
Cloud Hosting and Page Load Speed
In Cloud Hosting, the resources needed for running and maintaining a website are distributed across multiple servers which work together. The following features of Cloud hosting make Cloud Hosted websites work at supersonic speeds.
In Cloud Hosting, since a website is hosted on multiple servers and the resources such as RAM, CPU, etc. are distributed, the latency is kept at bay. If one server experiences excessive load, then other servers step-in and avoid delay in data transfer.
Most Cloud Hosting providers spread their network across different locations. When a visitor lands on a website, the server that is nearest to the user services the request leading to a quicker response time.
Some Cloud Hosting providers use storage architecture like Ceph which adds reliability … Read More
There are a lot of ways to get a web site off the ground. If you are good at figuring out technology there are a number of ways to ‘do-it-yourself’ and get a result that works for you. If nothing else you may gain a bit of respect for the time it takes a web designer to customize a site to your specifications. You can not go wrong to read some tips from LinkHelpers Phoenix Web Design Company
There are sites that can hook you up with web designers who work very inexpensively or you can find one in your area. Don’t forget the adage that you get what you pay for. Low price should not be your only consideration in finding a web designer. You’ll want to look at their portfolio, talk to them, see if they express an understanding of what you want and that you feel that you can speak with them easily.
Even if you like every site a designer has designed, this site is yours and should have your input and stamp on it. If you tell your designer to ‘be creative’ you need to accept that they will be creative in a way that they define creative which may not be the same as your definition. Look at this venture as a collaboration. They will have ideas to offer based on their experience that you should be open to. You should not hesitate to ask their opinion.
Before you meet with the designer, make sure you have spent time really thinking about the site, how you want it to look, and what you want from it. Look at other sites to get ideas and think about what you like and don’t like.
Think about color, navigation, images, and wording. Once you have an idea … Read More
