Europe gets its first TWDM-PON field trial

Vodafone is conducting what is claimed to be the first European field trial of a multi-wavelength passive optical networking system using access equipment from Alcatel-Lucent.

The time- and wavelength-division multiplexed passive optical network (TWDM-PON) technology being used is a next-generation access scheme that follows on from 10 gigabit GPON (XG-PON1) and 10 gigabit EPON. 

“There appears to be much more 'real' interest in TWDM-PON than in 10G GPON,” says Julie Kunstler, principal analyst, components at Ovum.

FSAN adds WDM for next-generation PON standard

The Full Service Access Network (FSAN) group has chosen wavelength division multiplexing (WDM) to complement PON's traditional time-sharing scheme for the NG-PON2 next-generation standard. 

"The technology choice allows us to have a single platform supporting both business and residential services"

FSAN close to choosing the next generation of PON

Briefing: Next-gen PON

Part 1: NG-PON2

The next-generation passive optical network (PON) will mark a departure from existing PON technologies. Some operators want systems based on the emerging standard for deployment by 2015. 

“One of the goals in FSAN is to converge on one solution that can serve all the markets"

Derek Nesset, co-chair of FSAN's NGPON task group

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.)
