Fiber to the x
From Wikipedia, the free encyclopedia
Fiber to the x (FTTX) is a generic term for any network architecture that uses optical fiber to replace all or part of the usual copper loop used for telecommunications. The four technologies, in order of an increasingly longer fiber loop are:
- Fiber to the node / neighborhood (FTTN) / Fiber to the cabinet (FTTCab)
- Fiber to the curb (FTTC) / Fibre to the kerb (FTTK)[1]
- Fiber to the building (FTTB)
- Fiber to the home (FTTH)
In the actual deployments, the difference between FTTN and FTTC is quite subtle and is mostly that the latter is nearer the customer than the former.
The poorly-defined term fiber to the premises (FTTP) is sometimes used to describe FTTH and/or FTTB.[2]
[edit] Technologies
The two main technologies used for these architectures are VDSL2 (used in FTTN, FTTC and in some FTTB deployments) and PON (the one used in FTTH/FTTP and in some FTTB deployments)
