Next-Gen PON: An interview with BT

An interview with Peter Bell, Access Platform Director, BT Innovate & Design on next generation passive optical networks (PONs). These include 10 Gigabit Ethernet PON (EPON) and Gigabit PON (GPON) and wavelength division multiplexing PON (WDM-PON).

Peter Bell, Access Platform Director, BT Innovate & Design

Q: The status of 10 Gigabit PON – 10G EPON and 10G GPON (XG-PON): Applications, where it will be likely be used, and why is it needed?

PB: IEEE 10G EPON: BT not directly involved but we have been tracking it and believe the standard is close to completion  (gazettabyte: The standard was ratified in September 2009.)
