BIDIRECTIONAL, RAMAN EXTENDED GPON WITH 50 KM REACH AND 1:64 SPLIT USING WAVELENGTH STABILISED PUMPS
Derek Nesset1, Kristan Farrow1, Paul Wright1; 1BT, United Kingdom.
We present an experimental demonstration of GPON reach extension to 50 km with a 1:64 PON split using Raman amplification of the upstream signal with wavelength stabilised pump lasers and class C+ transceivers.

A ring+tree PON is demonstrated from a 78 km reach rural to an urban 1:128 split configuration with field-deployed fibers at >31 dB budget and RSOA or SOA/REAM at the ONU.
 
Th.12.C.4 • 12:00
REACH EXTENDERS BASED ON OPTICAL AMPLIFICATION FOR XGPON1 OPTICAL ACCESS NETWORKS
Fabienne Saliou1, Rui Xia1, Quang Trung Le1, Philippe Chanclou1, Ari Tervonen2,3, Marco Mattila2,3, Tuomo von Lerber2,4, Werner Weiershausen2, Seppo Honkanen3, Franko Küppers4; 1Orange Labs, France; 2Luxdyne Ltd, Finland; 3School of Electrical Engineering, Aalto University, Finland; 4Institute of Microwave Engineering and Photonics, Germany.
 Reach Extenders based on Semiconductor Optical Amplifiers are experimented on a commercial prototype XGPON1 system. Bidirectional performances are evaluated and improved using a novel SOA operation. Up to 50dB of optical budget is obtained
 
Th.12.C.5 • 12:15
AN UPSTREAM REACH-EXTENDER FOR 10GB/S PON APPLICATIONS BASED ON AN OPTIMISED SEMICONDUCTOR AMPLIFIER CASCADE
Stefano Porto1, Cleitus Antony2, Peter Ossieur2, Paul D. Townsend2; 1Electrical and Electronic Engineering, Tyndall National Institute, University College Cork, Ireland; 2Physics, Tyndall National Institute, University College Cork, Ireland.
We present a reach-extender based on a semiconductor amplifier cascade which achieves 12dB compression of the input dynamic range whilst also limiting patterning. A 70km reach is demonstrated over a 32-split 10Gb/s passive optical network
 
Th.12.C.6 • 12:30 (Invited)
NETWORK OPERATOR PERSPECTIVE ON WDM-PON SYSTEMS AND APPLICATIONS
Derek Nesset1; 1BT, United Kingdom.
An overview of WDM-PON technology is presented and potential applications in telecommunication operator networks are reviewed. Operational issues concerning WDM-PON technologies are highlighted.
