Standards Update on 5G Transport, Higher Speed PON, Latest OTN Technologies and Interoperable Optica

Tuesday, 10 March, 14:45 - 15:45

Theater III

Session organized by International Telecommunication Union (ITU)


Session Description

The international standards (ITU-T Recommendations) developed by Study Group 15 detail technical specifications giving shape to global communication infrastructure. The group’s standards define technologies and architectures of optical transport networks enabling long-haul global information exchange; fibre- or copper-based access networks through which subscribers connect; and home networks connecting in-premises devices and interfacing with the outside world.

This includes the development of standards for the optical transport network, access network, home network and power utility network infrastructures, systems, equipment, optical fibres and cables and the related installation, maintenance, management, test, instrumentation and measurement techniques, and control plane technologies to enable the evolution toward intelligent transport networks, including the support of smart-grid applications.

This session presents hot topics from the latest development of international standards (ITU-T Recommendations) within ITU-T SG15, in particular, standardization work related to transport network support of IMT-2020/5G mobile, higher speed PON (Passive Optical Network) including the use of wavelength division multiplexing, latest OTN (Optical Transport Network) and other transport technologies that are applicable to IMT-2020/5G mobile radio access. This session also discusses interoperable optical interfaces at 200 Gbit/s and 400 Gbit/s per wavelength, including the development of standardized interoperable interfaces using optical DP-16QAM modulation.

Optical Access Standardization in ITU-T SG15 Q2

Fiber continues to make major gains in the access market. This is enabled in part by the optical access systems being standardized in ITU-T Q2/15.  This talk will review these systems, including XG(S)-PON, 50G-PON, multichannel systems, and bidirectional optics.

Dr. Fabio Pittalà, Principal Engineer, Huawei
Optical Multi-Vendor Interoperable Specifications in ITU-T SG15/Q6

Optical multi-vendor interoperable specifications currently under development in ITU-T SG15/Q6 will be discussed.

Dr. Stephen J. Trowbridge, Consulting Director of Standardization / Chairman of ITU-T Study Group 15, Nokia
Transport Network Evolution

This presentation introduces recent developments in evolving optical transport networks (OTN) to higher transmission speeds (e.g., 400G), including related developments regarding FlexE, FlexO, and network technology in support of 5G mobile transport.



Dr. Frank J. Effenberger, Vice President Fixed Access Network Lab, Futurewei Technologies
Dr. Effenberger has worked in the optical access field at Bellcore, Quantum Bridge Communications (Motorola), and Futurewei Technologies, where he is now the Vice President of the fixed access network lab.  His team works on forward-looking fiber, copper, and coax access technologies, and has produced the world’s first prototypes of XG-PON, TWDM-PON, Few Mode PON,, and DOCSIS 3.1.  Frank is the rapporteur for ITU-T Q2/15, chair of IEEE 802.3cp, and is a Fellow of the OSA, the IEEE, and Huawei. He holds over 110 US patents.


Dr. Hiroshi Ota, Study Group Advisor, International Telecommunication Union (ITU), Switzerland

Dr. Hiroshi Ota is Advisor for ITU-T Study Group 15, which develops standards on networks, technologies and infrastructures for transport, access and home.  He supports ITU-T SG15 by providing secretariat services as a staff member of ITU.  He also coordinates the work on disaster relief and emergency communication within ITU and with related organizations.

Before joining the ITU in January 2009, he was with Nippon Telegraph and Telephone Corporation (NTT), Japan.  He actively participated in standardization activities from 1992 to 2008 including ITU-T SG13, SG15, IEEE 802 LAN/MAN Standards Committee and IETF taking several leadership positions.


Dr. Fabio Pittalà, Principal Engineer, Huawei
Fabio Pittalà received his Ph.D from the Technical University of Munich (TUM) and his M.Sc. in Telecommunication Engineering from the Technical University of Denmark (DTU).

He is currently working as a Principal Engineer on high-speed coherent transmission systems at the European Research Institute of Huawei in Munich, Germany. He authors 30+ conference/journal papers and 10+ patents.

He is also an active contributor to ITU-T SG15/Q6 mainly focusing on the specifications of interoperable coherent 100 Gbit/s, 200 Gbit/s and 400 Gbit/s optical interfaces for Recommendation ITU-T G.698.2.
