What is FTTH (Fiber To The Home)?

By Steve Rogers,
The term is used when the fiber is deployed from the optical connection node (where the operator's transmission equipment is located) to the subscriber. FTTH differs from ADSL, which uses copper networks combined with optical fiber.

 Much faster access to the Internet, possibility of watching HD television, multi-connection, etc. New uses linked to better quality of speed appear and the number of subscribers to an FTTH network has increased by 70% in one year (at 2nd quarter 2013)! For local authorities, having a broadband connection has even become an issue of attractiveness which can attract residents or increase the value of a property.
Optical fiber deployment: from operator to users
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

If we detect N photons from a coherent state of light for a measurement,

By Steve Rogers,
Short answer: A good order of magnitude rule of thumb for the maximum possible bandwidth of an optical fibre channel is about 1 petabit per second per optical mode. So a "single" mode fibre (fibre with one bound eigenfield) actually has in theory two such channels, one for each polarisation state of the bound eigenfield. I'll just concentrate on the theoretical capacity of a single, long-haul fibre; see roadrunner66's answer for discussion of the branching in an optical network. The fundamental limits always get down to a question of signal to noise in the measurement (i.e. demodulation by the receiver circuit). The one, fundamentally anavoidable, noise source on a fibre link is quantum shot noise, so I'll concentrate on that. Therefore, what follows will apply to a short fibre: other noise sources (such as Raman, amplified spontaneous emission from in-line optical amplifiers, Rayleigh scattering, Brillouin scattering) tend to become significant roughly in pro

ingle-mode fiber uses only one mode of light to propagate

By Steve Rogers,
Single-mode fiber uses only one mode of light to propagate through the fiber-optic core. In single-mode fiber-optic cabling, the core is considerably smaller (8 to 10 microns) in diameter. A 9/125 optical fiber indicates that the core fiber has a diameter of 9 microns and the surrounding cladding is 125 microns in diameter. The core in single-mode fiber is only approximately 10 times larger than the wavelength of the light it is carrying. This leaves very little room for the light to bounce around. As a result the data carrying light pulses in single-mode fiber are essentially transmitted in a straight line through the core. Typically single-mode uses a laser light source, which is more expensive to produce, requires higher levels of safety awareness, and can transmit data further than multimode. Single-mode (such as a 9/125) can carry data up to 3000 meters (9,840 ft.) according to the existing standard (note that the standard in this case may not reflect the physical limitation)

Copper, fiber or wireless network?

By Steve Rogers,
While for decades the debate about which one is better (copper, fiber or wireless network), increased interest in discussing wiring, it is now becoming irrelevant.  In communications technology and the end-user market, it seems, it has already been decided that, in general terms, the transmission media and many networks must combine all three.  Currently, for the designer of wiring networks, especially fiber optic networks, and for their clients, the task of deciding which means to use once the communication systems were chosen is very simple. Long-distance and external plant Almost all telephony system cables are fiber optic, except telecommunications systems that still use copper for the final connection to the home.  CATV companies use a high-performance coaxial cable inside homes, but it connects to a  fiber optic  backbone  network .  Backbone (  backbone  ) Internet consists of fiber in its entirety.  Most commercial buildings that are in heavily populated areas receive d
