10 Gigabit Ethernet passive optical network

Ethernet in the connection area is characterized by Ethernet in the First Mile( EFM) and Ethernet Passive Optical Network( EPON), the passive optical Ethernet. In order to meet the increasing demand for high bandwidth for multiple TV channels, Internet and voice communication, the IEEE working group802.3av deals with the topic: 10 Gigabit in the connection area. This technology represents an extension to EPON.

In terms of connection technology, 10 Gigabit EPON( 10GEPON) specifies a distribution network between a central exchange and the home network that supplies up to 32 households with 10 Gbit/s via FTTH. The fact that just 32 households are supplied via one node was determined by means of a demand analysis, according to which each household should have a bandwidth of 300 Mbit/s in the future (2010). This analysis was based on the assumption that a medium-size household would have four different HDTV television programs or Large Screen Digital Imagery( LSDI) running at the same time, requiring up to 150 Mbit/s, as well as online games, Internet and voice communications.

10GEPON has two different data rates for downstream and upstream of 10 Gbit/s and 1 Gbit/s respectively, which are now transmitted on different wavelengths. In the upstream, the subscriber data is separated using TDMA.
