This EPON configuration will require as much fiber as in point-to-point
all-fiber (AF) networks, but it will still require only one transceiver in the OLT. This
allows much higher equipment densities, which is typically important in COs. In this
scenario, moving ONUs from one PON to another to balance traffic loads is a simple
matter of reconfiguring the access network at the fiber patch panel.
Initial Stages of Development of 10G EPONs
The effective data rate of 1 Gbps supported by the legacy IEEE 802.3ah compliant
EPONs is already not considered sufficiently future proof to assure revenue growth

within the next few years, mainly due to increased customer demand for bandwidth
intensive applications and explosive utilization of HD-TV and online gaming, once
available in the coverage area. Thus, development of higher capacity EPON systems
was advocated in 2006 during one of the IEEE plenary meetings [18], resulting in
the initial establishment of the 10G EPON Study Group. This Study Group quickly
identified the market potential and evaluated the technical feasibility of the future
10G EPON systems, resulting in submission of the project authorization request (PAR)
and its subsequent approval at the subsequent IEEE Plenary meeting.
