One morning, you connect to the internet when you arrive at the office, and everything has changed. Heavy attachments that you put long minutes to send or receive are transferred in seconds, the videos you streak are in high definition, your videoconferencing sessions are fluid and not jerky … This upheaval is the fiber and its hundreds of Mbps of bandwidth that have reached your business. A connection that did not happen with a magic router. Depending on whether you choose a FTTH link (Fiber to the Home) or FTTO (Fiber to the Office), Bouygues Telecom Business technicians will have to perform a certain number of operations before reaching you.
Cabinets not so mysterious
In the case of an FTTH connection, everything starts from the pooling point (PM). You probably have already seen these cabinets installed on the sidewalks of your city, without knowing what they contained. They are the ones who will accommodate the couplers and dispatchers and make the link between the network of the commercial operator, who has already drawn his fiber up to the PM, and that of the operator of the building which, like its name 'indicates, at the expense of the network within the building (or a suburban area or even a municipality, depending on the density of the area). Once this connection is made, just stay at the last meters to the very premises of the company. A technician will go on site to define in consultation with the customer the best method to pass the fiber. The priority is to hide the cable as much as possible, using false ceilings or chutes for example, and take it to the optical connection point, to which the company can connect its own internal network. About half of the FTTH connections are made in less than 15 days; 95% are in less than 40 days.
One cable, 288 fibers
An FTTO fiber, on the other hand, is a dedicated fiber for the company, a point-to-point link between the operator and his customer. It does not pass through the PM, but starts from one of the network access points of the operator. In intramural bets, for example, Bouygues Telecom Entreprises has deployed between 20 and 30 access points to its core network. When a company wants an FTTO connection, the operator starts from the nearest access point and then determines the best path for passing a fiber specifically for it. In the majority of cases, this path passes through existing underground ducts and used until then for the copper network.
Several scenarios are then possible. If an optical cable has already been deployed in the sleeve, it is likely that the 288 fibers it contains are not all used for FTTH connections and some are free to create an FTTO link. If no fiber is available but the sleeve has enough space, the technicians are responsible for passing a new cable. Finally, if the sheath is complete, the operator searches for or creates another path. After this design phase, the various fibers that will compose the FTTO link are fused using an electric arc to obtain an optical continuity. In the company's premises, the procedure for determining the passage of the cable is similar to that of the FTTH. However, an additional pre-visit is organized because the offices are often located in larger buildings requiring more identification. A few weeks are enough for the link to be operational.
Shared or dedicated?
Apart from a few holes in its walls, the process of deploying FTTH and FTTO fibers therefore generates few constraints for the client company. It remains to be seen which of the two offers best suits his needs. If the creation of a direct link in FTTO is logically more expensive, it allows the operator to offer in particular a very high symmetrical and guaranteed high speed and a GTR (guarantee of recovery time) of 4 hours. More than the size of your organization, it is therefore the criticality that the fiber connection represents for your business that is to be considered. Once fixed, the lanes of the fiber are wide open to you.
