Optical fiber: know everything about the high-speed
FTTH-FTTB: different modes of connection
While Orange, SFR and Free engage in the battle of the optical fiber, it is important to distinguish between different types of connection for individuals.They can be classified into four categories.
FTTH dedicated (point to point or P2P) allows each subscriber to have its own fiber to the home node optical connection (NRO) fitted by the provider.Technically, this is the most scalable solution, since the ISP can further control the flow and if necessary increase the bandwidth.By cons, FTTH costs more dedicated and administrative barriers (Trustee building, building ...) can adversely affect its deployment.
FTTH shared (Point to multipoint or GPON) is a different device.Optical fiber between the subscriber and the NRA is shared through a splitter additional installed upstream.In short, the fiber from the NRO is then divided so that each subscriber gets very high speed.This solution is less expensive to implement but it does not easily adjust the flow.
FTTB connects the building to the NRO through the optical fiber.However, the foot of the building to the subscriber, it is VDSL2 (xDSL technology outperforms ADSL) is used. So these are the fiber optic and copper pair that are used to facilitate the deployment, but at the expense of speed of bandwidth that will be limited to 50 or 100 Mbit / s for the lucky ones.
The FTTLA is used by the cable operator Numerically. Fiber to the last amplifier is gradually replacing the old cable network .In FTTLA, optical fiber connects the operator's network to a "hub" that feeds the optical nodes then installed at the foot of the buildings. With this architecture, only the terminal part of the network consists of coaxial cables on the last meters to the subscriber.
