FTTH is the abbreviation of "Fiber To The Home", is a transmission method for fiber optic communication, which is currently the best mode for full service, high bandwidth fiber optic access requirements.
FTTx is the abbreviation of “Fiber To The x”, a general term for all kinds of fiber optic communication networks, where x represents the destination of the fiber optic line,mainly include: FTTH, FTTP, FTTB, FTTC, FTTD, FTTN, FTTR, FTTA, FTTO, FTTSA, etc.
Data center usually refers to the centralized processing, storage, transmission, exchange and management of information in a physical space. The emergence of data centers has led to the understanding of people from the quantitative, structured world into the uncertain and unstructured world, which will gradually become a part of the infrastructure of modern society.
XG-PON (10 Gigabit Passive Optical Network) is a new generation of fiber optic access technology evolved from the existing GPON technology. It is an upgraded version of GPON aimed at providing higher transmission rates and longer transmission distances.
XGS-PON is an fiber access network technology that supports symmetric 10Gbit/s transmission speeds. XG-PON and XGS-PON both belong to the GPON series, and from the technical roadmap, XGS-PON is the technological evolution of XG-PON.
Optical Distribution Network (ODN) is an FTTH fiber optic network based on PON devices. It is the part of the optical access network that provides optical transmission from the optical line terminal (OLT) to the optical network unit (ONU) and in the opposite direction. It is used to allocate optical signal power and provide a physical channel for optical signal transmission.
EPON stands for Ethernet-based Passive Optical Network, it is a new hotspot for broadband access developed after ATM Passive Optical Network (APON), and one of the efficient access solutions to solve the bottleneck problem of broadband access.
GPON stands for Gigabit passive optical network, It is the latest generation of broadband passive optical integrated access standard based on the ITU-TG.984. x standard, which has many advantages such as high bandwidth, high efficiency, large coverage range, and rich user interfaces.
