Quickly understand FTTx / FTTC / FTTB / FTTH
What is FTTx?
FTTx is "Fiber To The x", which is a general term for various fiber-optic
communication networks. X based on the location of the fiber's
termination point. Such as x = H (Fiber to the Home), x = O (Fiber to the
Office) , x = B (Fiber to the Building). The FTTx technology ranges from
the central office equipment to the user terminal equipment, including
OLT (Optical Line Terminal), ONU (Optical Network Unit), ONT (Optical
Network Terminal).
Depending on the install location of the ONU at the user end of the
optical network unit, there are many types of FTTx, which can be divided
into fiber to Cabinet (FTTCab), fiber to curb (FTTC), fiber to building
(FTTB), fiber to the home (FTTH), fiber to the office (FTTO) and other
service forms. US operator Verizon refers to FTTB and FTTH as
fiber-to-the-station (FTTP).
FTTCab (Fiber To The Cabinet)
The traditional electric cable is replaced by optical fiber. The ONU is
placed at the cabinet. The ONU below uses copper wire or other media
to connect to the user.
FTTC (Fiber To The Curb)
Optical cables will be used from the central office to roadsides within a
thousand feet of home or offices. Generally, a potential broadband
transmission link that is very close to the user is laid first. Once there is a
need for broadband services, the fiber can be quickly led to the user and
the fiber can be brought home.
FTTB (Fiber To The Building)
It is a broadband access method based on optimized optical fiber
network technology, which uses fiber to the building and network cable
to the home to achieve the user's broadband access. Generally,
dedicated line access is adopted, which is easy to install and can provide
a maximum upstream and downstream rate of 10Mbps (exclusive).
FTTH (Fiber To The Home)
FTTH is a type of optical access network application that is closest to the
user except the FTTD(Fiber to the Desktop) by installing the ONU in
home or business users. PON technology has become a hotspot of
global broadband operators, and is considered to be one of the best
technical solutions to achieve FTTH.
FTTP (Fiber To The Premise)
FTTP is a North American term. It includes FTTB, FTTC, and FTTH in a
narrow sense, and extends optical fiber cables to homes or enterprises.
