What is GPON&EPON?

What is Gpon?

GPON (Gigabit-Capable PON) technology is the latest generation of broadband passive optical integrated access technology based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Most operators regard it as an ideal technology to realize broadband and comprehensive transformation of access network services. GPON was first proposed by the Full-Service Access Network (FSAN) organization in September 2002. On this basis, ITU-T completed the formulation of ITU-TG.984.1 and G.984.2 in March 2003. , The standardization of G.984.3 was completed in February and June 2004, thus forming the standard family of GPON.

What is Epon?

EPON (Ethernet Passive Optical Network), as the name suggests, is an Ethernet-based PON technology. It adopts point-to-multipoint structure, passive optical fiber transmission, and provides a variety of services on the Ethernet. EPON technology is standardized by the IEEE802.3 EFM working group. In June 2004, the IEEE802.3EFM working group released the EPON standard – IEEE802.3ah (incorporated into the IEEE802.3-2005 standard in 2005). In this standard, the Ethernet and PON technologies are combined, the PON technology is used in the physical layer, the Ethernet protocol is used in the data link layer, and the Ethernet access is realized by using the PON topology. Therefore, it combines the advantages of PON technology and Ethernet technology: low cost, high bandwidth, strong scalability, compatibility with existing Ethernet, and easy management.
