Program overview

FTTx (Fiber-to-the-x) "Fiber-to-the-x" is a general term for various optical fiber communication networks, where x represents the destination of the optical fiber line. It includes: FTTH fiber to the home, FTTP fiber to the premises, FTTC fiber to the premises Roadside/community, FTTN fiber to the node, FTTO fiber to the office, FTSA fiber to the service area, etc.


FTTx is the current new generation of optical fiber user access network, which is used to connect communication operators and end users. The FTTx network generally referred to at present is a passive optical fiber access network. The FTTx network structure can be either point-to-point (P2P) or point-to-multipoint (P2MP). At present, most FTTx networks use the P2MP structure.


Various technologies to realize FTTx


APON/BPON is an early standardized and commercial passive optical network technology, using ATM as the bearer protocol. It is basically no longer in use.



EPON is an effective combination of Ethernet technology and PON network structure. It uses Ethernet as the carrier, adopts a point-to-multipoint structure and passive optical fiber transmission.



GPON is a gigabit passive optical network or Gigabit passive optical network. GPON technology is the latest generation of broadband passive optical integrated access standards based on the ITU-TG.984.x standard (which can simultaneously carry ATM cells and ( Or) GEM frame), which has many advantages such as high bandwidth, high efficiency, large coverage area, and rich user interface.


FTTx deployment, inspection, maintenance

FTTx network planning is a necessary condition for the successful deployment of FTTx. Component testing, field welding and termination verification are still one of the most important factors for FTTx deployment. Improper splicing, contaminated connectors, or microbending of optical fibers can all cause optical loss and degradation of service quality. An effective installation verification plan helps reduce risks
