Telecom’s Growth Drives

fiber-optic-installation-1VINCI Energies, through its Axians brand, has deployed optical fiber on behalf of large national operators in many regions, such as the Moselle and French agglomerations such as Lille, Toulouse, Bordeaux, the Paris suburbs, as well as abroad as in Poland and Germany. Axians also offers a specific offer to operators to connect small and medium-sized businesses to these very high speed networks. VINCI Energies is therefore helping to reduce the digital divide and promoting access to very high With all these options of external plant installations, how do you start? With a good map. Not just a street map or a topographic map; A system of satellite images obtained along the streets is much better, like the one provided by “Google Maps”. Creating a street map is the first step, and you must identify the other public services on the map, along the entire route, and verify it with the groups that report on existing public services to prevent contractors from damag

Launched six and a half years ago, the deployment of very high speed networks is advancing quickly. According to the Observatory of High and Very Haud Debit of Arcep , the total number of homes eligible for very high speed offers as of March 29, 2019 20.8 million homes and 14.5 million in Broadband. In addition, there is an increase in eligible housing on end-to-end fiber optic networks (FTTH). There are now 5.3 million FTTH subscriptions in the first quarter of 2019 and 9.5 million Very High Speed ​​subscribers (all technologies combined with a connection of more than 30 Mbit / s). However, the UFC association made a point of emphasizing in a report of March 21, 2019 , the inequalities of quality of Internet connection which continue to exist according to the French communes. Thus, if  34.8% of the population have a connection of more than 100 Mbps (optical fiber), 17.4% between 30 and 100 Mbps (VDSL, 4G, ...) and 28.6% between 8 and 30 Mbps (ADSL), there are still 9% between 3 a

Fiber optics follows an articulated path in two stages: the deployment "horizontal" is the fact of all operators, which will lay cables in urban areas - essentially - like rural, the "vertical" deployment is performed by an operator, chosen by the condominium, of connecting the fiber drawn to the bottom of a building to each of the apartments. Why is it often said that ADSL is the “ancestor” of fiber? As its name suggests - for most English speakers among us at least - ADSL provides an asymmetric speed. That is to say that the data flow carried is more substantial in one direction than in the other. Here, the upstream data rate of an ADSL communication (upload) is much lower than the downstream rate (download). The maximum available speed in the downward direction varies in particular according to the attenuation undergone by the signals during their journey on the subscriber's line, the length and the diameter of the line… but rarely exceeds 20 Mbit / s

Fiber optics provide ultra-fast Internet access, even for long distances. New services are therefore gradually appearing alongside the development of telecom networks.  Examples include real-time, high definition video streaming from mobiles to other mobile or fixed equipment.  But more generally the announced revolution concerns the generalization of communication with all kinds of objects with a chip from anywhere ... even between the objects themselves (example: receiving an SMS or a message on TV because his boiler is having a problem or a gate has opened in such a place). The deployment of optical fiber to the subscriber (FTTH) is therefore one of the major projects in the coming years.  It is accelerating in France and represents a significant job creation potential, but it also requires the development of new skills. These skills are mainly grouped in two areas: The implementation of an FTTH network (or operator) and the measures to estimate the quality of this implementation w

It is prudent to install indoor fiber optic cables inside "corrugated subducts" oranges to facilitate cable installation and protect it from future damage. The bright orange corrugated subducts will allow any worker in the future to identify the fiber optic cable and avoid possible damage. The additional initial cost of the corrugated subducts is offset by the simplification of the installation, which saves working time.  Use of cable ties Fiber optic cables, like all telecommunications cables, are sensitive to compression loads. The cable ties used with many cables, especially when fitted with an installation tool, damage the fiber optic cables, weakening the cable and making it possible to break the fibers. When cable ties are used, they should be adjusted by hand, but not so much, allowing the cable tie to be moved along the cable by hand. Then the excess cable tie should be cut to avoid being adjusted in the future. Velcro cable ties are preferred for fiber optic ca

Most precision cutters that are used to splice or terminate pre-polished splice connectors hold the fiber after passing through it, so the only problem is getting rid of it. We recommend using a disposable container such as those used for soups in take-out restaurants. Use it for all fiber debris and then seal it and dispose of it properly.  You can also organize your workplace to avoid problems. Use black plastic cloth for the work surface. It will be easier to see the fibers with which you are working with the black background and you can handle them more carefully. Any fiber that falls on the mat will be easier to find to be discarded.    Some technicians prefer to adhere a piece of double tape or black insulating tape on the mat and that the fibers stick to the adhesive surface and then discard the tape when finished.  I prefer to simply use a disposable container and put each remaining fiber in the container, instead of leaving them exposed on the work surface. Other s

What should be kept in mind of the test equipment is that you should know how to use them and you should always verify them before taking them to the work area. The batteries should be changed or charged, test the reference cables and, most importantly, the user should take a few minutes to refresh his memory on how the instrument is used. The work area is not the place to discover that the equipment is not ready for use.  Training and security Fiber optic training The number one rule of fiber optic installation is never to try to install a new type of component or start a new application without proper training. Not having the knowledge or faculties related to that component or that application makes it impossible to ensure the success of the work and the jobs can be very expensive. In FOA we know many examples of facilities that went wrong and had unfortunate consequences. No one can know everything or take all possible training courses to cover all aspects of fibe

Elimination of abandoned cables Unless indicated by the owner or another agency that unused cables are reserved for future use and the cables are marked accordingly, it is necessary to remove abandoned fiber optic cables (cable ending with a connector and not on other equipment, and that has no identification with a label for future use) as required by the National Electricity Code (NEC) or local codes. At the choice of the owner of the place, the contractor will also be asked to remove other cables (for example copper or electricity communications). Cable removal consumes more time than installation since each cable must be carefully identified and removed so as not to damage other cables. No cable must be cut to be removed unless it has been properly identified as the cable to be removed.  All cables must be recycled properly. Most communications cables have value as scrap, not only for copper conductors but also for other metallic elements, including some plastics. Also Rea

Contact with local authorities In the case of facilities in an external plant that is carried out in public spaces, it may be necessary for local authorities to send supervisory personnel, police forces or transit agents. For this reason, they must also be involved in the organization. If project inspections are required, they should be coordinated in a way that minimizes work interruptions. Personnel in charge of supervision are responsible for safety in the workplace so they must have appropriate contact information, including public services such as police, fire, and ambulance service. Daily meetings are recommended in the case of projects lasting several days to review the progress of each day. At these meetings, at least the construction site supervisor and a network user representative in charge of the project must be present. While everything is in order, these meetings should not be very extensive. In the case of larger projects, workplaces must be guarded by night sec
