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.

Photonic integration specialist OneChip tackles PON

Briefing: PON

Part 1: Monolithic integrated transceivers

OneChip Photonics is moving to volume production of PON transceivers based on its photonic integrated circuit (PIC) design. The company believes that its transceivers can achieve a 20% price advantage.

"We will be able to sell [our integrated PON transceivers] at a 20% price differential when we reach high volumes"

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.)
