Un peu de lecture!

…Ces fibres optiques noires sont parfois installées par des collectivités territoriales dans le cadre de Délégation de Service Public (DSP) pour encourager l’arrivée du haut débit sur leur territoire. Les collectivités peuvent en effet investir dans des réseaux de communications électroniques ouverts…

…A Paris, la fibre noire est déployée dans les égouts (plutôt qu’en chaussée) pour faciliter le déploiement. …

Quels en sont les avantages ?

L’avantage principal de la FON, c’est l’évolutivité : au fur et à mesure que les besoins augmentent, on peut passer de 1 Gbps à n * 10 Gbps, et le seul coût associé va être celui des équipements, mais il est marginal. Idem pour les services : si de nouveaux besoins se présentent, il suffit d’éclairer de nouvelles longueurs d’ondes.

L’émergence de la fibre noire et son histoire

Une grande partie du coût d’installation des câbles de fibre optique est lié au travail de génie civil requis. Cela inclut la planification et le routage, l’obtention d’autorisations, la création de canaux pour les câbles, et enfin l’installation et la connexion. Par exemple, pour l’installation du réseau de fibres optiques de la ville d’Amsterdam, environ 80% des coûts impliqués étaient ceux de la main d’œuvre. Il est donc judicieux de prévoir et d’installer beaucoup plus de fibres que ce qui est nécessaire pour la demande actuelle ; et ainsi de prévoir une expansion future du réseau fibre optique. Cela permet aussi de prévoir une redondance du réseau en cas de défaillance ; c’est ce que l’on appelle des spares.

What does The City have to do with dark fibre?

The City has been installing dark fibre for City use over the years and licenses out excess dark fibre to other organizations to encourage innovation, economic growth and competition within our community.

As The City continues to build out dark fibre infrastructure, developers and builders should begin to understand what they will need to provide long-term. Doing so will give you a competitive edge in your market place – to the benefit of investors, buyers and communities.

In Calgary, any organization can access existing municipal dark fibre network to achieve high levels of performance, a highly secure network and superfast speeds.

Don’t feel left out – we can help you get connected !  Start here to learn more about The City’s dark fibre program and the competitive edge it can bring to your projects

…Helping to ensure a strong economy, and acting as a catalyst for business, investments were made to upgrade infrastructure at Kelowna International Airport and we launched the city’s own dark fibre network to bolster our thriving technology sector.



…To make the case for investing in a government-owned fiber network, many communities define ROI more broadly and consider the “beyond the balance sheet” benefits that such a network would deliver. These benefits have nothing to do with traditional financial measures. Rather, they represent the return to the community in terms of such largely intangible societal benefits as enhancing health care quality, narrowing the digital divide, providing enhanced educational opportunities to schoolchildren, delivering job search and placement opportunities at public computer centers and helping isolated senior citizens make virtual social connections….

… A government fiber optic network that links all government facilities eliminates the jurisdiction’s ongoing cost of leasing circuits. This represents an easily quantifiable present value on the financial statement and is as close as possible to a guaranteed line item: Build the network and you will shave this amount from your accounts payable…

Dark or lit fiber to community anchors. A well-established revenue stream is derived from providing either dark fiber or lit services for nongovernment institutions. This model hews very closely to the service delivered to government operations – but instead of helping the government avoid its own costs, it creates a revenue stream for the operator. By providing reasonably priced fiber to qualified nonprofit and community organizations and facilities, the network operator also supports the needs of anchor institutions – which in turn support the citizens….

A project like this must mean tax hikes, right? Think again! There are examples in Canada where taxes didn’t need to be raised to pay for broadband infrastructure. In Olds, Alberta, the profits from O-Net are projected to completely pay off the community’s loans from the government within 10 years, due to the booming business the network has created for the municipality. If just one third of the population subscribes to O-Net, the project pays for itself.


With open access community-owned networks, telecom companies have the chance to profit from infrastructure that they didn’t pay to build. It widens the service area of existing ISPs and allows them to reach an expanded customer base. Not to mention, it gives all companies — including indie providers — an equal shot to get in on the market. That’s a great deal!


Municipal broadband networks exist all over the world, in both urban and rural communities. Examples in Olds, Alberta and Sandy, Oregon illustrate how community-owned networks in North America can do wonders for the livelihoods of those who live there. Similar projects are even springing up thousands of miles away, in places like the Netherlands and Singapore.




…And Huntsville isn’t borrowing money to do this. Instead, it plans to use the revenue that it gets from leasing this dark fiber to tenants to fund the expansion of its network. ..
