Optical fiber: first funding networks "project bonds"
|2014/07/23 21:16:59||日常 | fiber optic lighting|
Europe's financial contribution to the high speed broadband infrastructure in France through a bond backed by the European Investment Bank.
EIB sign, July 23, 2013 at the headquarters of the Caisse des Dépôts, in the presence of Neelie Kroes, European Commissioner for the Digital Economy, the agreement related to this loan granted Axione Infrastructures.
It will be a priori the first funding "project bonds" type that will be used in France in the deployment of fiber optic networks.
These bonds differ from bank loans and government subsidy. They primarily intended to stimulate financing on capital markets, major infrastructure in energy, transport and telecom projects.
Offering the support of the EIB, these loans have a better quality of credit with more favorable financial terms for the borrower.
Free EIB financed in 2010 and 2012
The amount of the loan granted to Axione Infrastructure is of the order of € 191 million. This amount will be used for the deployment of very high speed networks in regions in which the company is involved.
Axione Infrastructure is a holding company owned 15% by companies Bouygues group, 30% by the Caisse des Dépôts and Groupe Caisse d'Epargne 55%. It operates through 14 public service delegation in equipment areas with broadband, on behalf of local authorities.
In fact this is not the first time the Bank is involved in high-speed networks in France. Free has already received 200 million euros granted by the EIB in 2012 for the deployment of next-generation fixed networks after an initial contract funding of EUR 150 million signed between the EIB and the Iliad in 2010. But it was not of bonds using the mechanism of "project bonds"

Brittany will receive € 140 million from the state to finance the deployment of its optical fiber network over its vast territory. The ceiling of the grant may be increased to € 152 million in case of need to build telecom networks collection.
This grant is funding the program of future investments, intended to help local authorities under the government plan France very high speed. Besides Brittany, Alsace and five departments were beneficiaries of these funds released by the Government on 17 July 2014.
This "manna" is good news for the joint association of territorial cooperation Mégalis Britain. It produces and manages the UK High Speed Broadband project, with the aim of deploying fiber to the entire region in 2030.
The region also placed on the European Regional Development Fund (ERDF) to complete this financing. The cost of implementation of the first phase of deployment of the regional infrastruture is estimated at 600 million euros.
The Joint Mégalis union officially launched in late 2013, the first tranche of work of Brittany Superfast Broadband program for nearly 100 million euros.
In this first phase, four medium-sized cities - Auray, Kergloff, Lamballe and Redon - and twenty more rural areas will be equipped with fiber optics.
Fiber arrives at campsites

At a time when seven new local authorities will benefit from funding under the plan France high throughput government, optical fiber sometimes where you least expect it sometimes. In campsites, for example. Yet it is these resorts as optical Internet arrives this summer 2014 in the French countryside. At least those where the chain of upmarket camping Yelloh! Village has installed its centers.
And who says upscale, said optical fiber. "We crossed the no install fiber optic and WiFi individually at each location, each mobile home and each property because it is the only way we satisfy customers 100%," says Bernard Sauvaire President direction Yelloh! Village. Thus, the provision of high speed broadband is now entering the selection criteria and holidaymakers becoming a competitive, so economic issue. "When I was 14-18 years old, not able to communicate on social networks or may not have a good internet connection, it arbitrator choosing a family. "Or how the dictatorship of the internet intends to impose its criteria of choice for both leisure and give birth to a whole generation of campers connected.
Home automation at the end of the fiber
To equip a "majority" of 64 campsites chain, Bernard Sauvaire uses Covage the infrastructure specialized in providing local communities through the deployment and operation of operator 23 so far, networks public initiative. Besides access to the Internet with broadband and distribution of television services, to deploy fiber services automation or "mobile home" server. Door opening, water temperature now controlled remotely. As stopping water heaters and other electrical appliances off automatically at the start of the holiday. Or how to leave with peace of mind... to better face the fall.
Glass fiber and composite materials in the communications industry shine
|2014/07/16 15:18:10||日常 | fiber optic lighting|
As the field of textile industry with the focus branches, glass fiber and composite materials, with its excellent performance and relatively low cost of a new energy sector, the construction sector, transportation, power engineering, marine engineering and environmental engineering and other fields of market development focus. Today, with the advent of "big data" era, glass fiber composites have gradually entered the field of communications, become the communications industry, "darling." British telecom giant Hull City KC company official said, glass fiber and composite materials into steel raw materials make up 70 percent of the defects, it also brings unforeseen development space for the communications industry, it will set off in the era of big data a "communications revolution."
Satellite receiving antenna is the key equipment of satellite ground station, which is directly related to the stability of the quality of reception of satellite signals and systems. Material requirements of the satellite antenna is light weight, strong wind resistance, aging resistance, high dimensional accuracy, no deformation, long life, corrosion resistance, can be designed reflective surface. Traditional production of steel and aluminum material is generally used stamping fabrication, thin thickness, corrosion intolerance, life is short, generally only 3 to 5 years, increasing the use of limitations. The use of glass fiber composite material, according to SMC molding process for the production, good dimensional stability, light weight, anti-aging, strong wind resistance, but also according to different requirements designed to improve the strength of the ribs, the useful life of more than 20 years, can be designed laying wire mesh and other materials to achieve satellite reception function, performance and technology to fully meet the requirements, the effect is very good, outdoor maintenance, good reception, prospects are very good.
Radome is a set of electrical performance, structural strength, stiffness, aerodynamic shape and other features required in one of the function structure, its main role is to improve the aerodynamic shape, the antenna system to protect against the effects of external environment, extend the life of the whole system, protection and position accuracy of the antenna surface. The traditional production of steel and aluminum materials generally, there are many disadvantages, such as the quality of larger impatience corrosion, single process, not overly complex shape molded products. Glass fiber material as a high performance material is particularly suitable for the production of new radar radome: conductivity can be completed by adding a conductive filler, structural strength requirements of the design according to the intensity and local changes in the thickness of the ribs to finish, shape available upon request made into different shapes, and corrosion resistance, aging resistance, light weight, can be hand lay-up, autoclave, RTM and other processes to complete, fully able to meet the performance requirements to ensure the radome and service life requirements.
In recent years, with the rapid development of mobile communications, the amount of mobile antennas dramatically increase the amount of protective outerwear radome as a mobile antenna also increased considerably. Mobile radome material must have wave permeability, outdoor anti-aging properties, wind load performance and batch consistency. In addition, its life must be long enough to install and maintain otherwise have brought greater inconvenience and increased costs. Before moving production to use more PVC radome material, but the material is resistant to aging, poor wind load capacity, short life, less quantity used. Glass fiber materials wave permeability good, strong anti-aging ability outdoor, good wind resistance, using pultrusion production batch production process consistency, the useful life of more than 20 years, in full compliance with the requirements of mobile radome, is gradually replacing PVC plastic, becoming the preferred mobile radome. Europe and other countries have banned the use of mobile radome PVC plastic radome, all using fiberglass radome.
Made of fiber-optic cable from the optical fiber is the future trend of development, and fiber materials are highly transparent glass fibers. An optical fiber made of glass fibers using the total reflection effect of the light, a refractive index smaller than the outer package has its outer layer of the bag. Thus, light can enter the core wire along the glass fiber occurs at the interface between the core and the outer layer of the bag is totally reflected snakes, not through the interface, if the sheath layer is tightly enclosed in the inner core. Compared to the previous ordinary cable, fiber optic cable has outstanding advantages. It's a staggering amount of information, the thickness of the hair fiber can pass tens Phone or 2000 circuit television. Fiber optic cable with a laser as a carrier, without external electromagnetic interference, high stability and confidentiality. In addition, low loss optical fiber cables, communication cables every few kilometers we should set up a relay station, and fiber-optic cables can transmit a continuous 30 to 70 kilometers, and therefore has a unique advantage in terms of long-distance transmission of information.
Car cloud computing
For building car cloud computing, on the one hand to meet future requirements of high-speed data transmission; other networks can also play a streamlined, reducing its costs. Therefore, the management of data flow and use of car users are also becoming increasingly important. While luxury cars has spent a lot of computer processors, but the advantage of multi-core technology that can reduce vehicle data nodes in the network, which means reducing the car handling and design complexity. The maximum value of the transmission rate up to a plastic optical fiber 1Gbit / s, compared to the coaxial 5Gbit / s, but with the increased data transfer rate, the system becomes complicated so that the respective costs continue to climb. The future application of glass fiber composite cable will solve the paradox rates and costs. After using a glass fiber composite material as the transmission media, the network bandwidth may be increased to 10Gbit / s, while fewer cable system to transmit the same amount of data needed, but it did not affect the durability of the network.
Signal to strengthen core
The traditional way to strengthen the signal made of glass fiber reinforced core materials, high performance vinyl ester resin as plastic material, but with the competition in the industry and to drive down the cost of continuing to pursue its vinyl ester resin has repeatedly lowered the quality requirements. Aramid fiber and glass fiber composite made to strengthen the impact of the emergence of a core of ordinary glass fiber reinforced core needs of the market. After the glass fiber and aramid fiber composites can be enhanced to strengthen the core strength of the signal, regardless of the strength or modulus are far more than steel and glass fiber reinforced fiber to strengthen the core; compound after the product not only has ultra-high tensile strength (≥ 1700Mpa ), and impact resistance, fracture, even in case of breakage still maintain the tensile strength 1300Mpa about; addition, the signal to strengthen the core soft texture, easy to bend, the minimum bend diameter of only 24 times the diameter can be achieved outdoors compact arrangement structure, appearance, its excellent bending properties, especially suitable for the layout of complex environments.
