10:25 – 10:45 NG-PON2 Optics and Photonic Integration Approaches

Hal Roberts, System Engineer and Architect, Calix

The first wave of NG-PON2 optics have been based on conventional bulk free-space optical modules. Photonic Integrated Circuits have always been considered a promising method of producing lower cost NG-PON2 optics, however the upfront development costs and timeframe have prevented these from being realized during early optics development. Recently promising work has begun on PIC based NG-PON2 optics. This presentation will examine how PIC based NG-PON2 optics might accelerate the availability of standards compliant lower cost optics.

10:45 – 11:05NG-PON2 ONU w / pluggable CATV overlay solution

Ben Hur, Senior Managing Director, Lightron

Based on the experience of developing 10G / 10G NG-PON2 ONT, NG-PON2 technology can be evolved into various applications by introducing the development of NG-PON2 triplexer product with CATV overlay function/solution in the form of XFP Pluggable Optic. The NG-PON2 triplexer developed product of this announcement provides compatibility to various platforms of NG-PON2 and provides the best solution for various additional application fields.

11:25 – 11:45 Access finally has wavelength flexibility

António Teixeira,  Co-founder/prof, Picadvanced/UA

Next Generation Passive Optical Networks 2 (NG-PON2) has challenged the traditional way of treating access real state, the wavelength, by introducing high-resolution tunable devices with the tight, 100GHz, channel spacing. This ITU path brought an extra dimension to the access space allowing flexible management of the network, opening windows to smooth pay as you grow deployments, coexistence with all present and close future technologies, as DWDM. This seems great, however, it pushed the current optical technologies, like GPON, which had wavelength freedom of tens of nm to tenths of nm (100GHz); from fixed wavelength to tight control tunable wavelength, and from 2.5Gbit/s to 10Gbit/s x 4 (or more). To solve this, great technical challenges had to be overcome and even some compromises had (and have) to be made to foster broad market adoption to happen sooner than later. PICadvanced, in this work, will present the current status of its solutions and the results of its production units which, given the facts, that is based on DML and fast thermal control in both Tx and Rx, show great potential to open the road to broad adoption of the standard.

Kevin Bourg, Director, Optical Network Architect, Corning

The convergence of both wireless and wireline technologies is becoming widely accepted as the future-ready platform to meet all subscriber needs. With NG-PON2 technologies evolving the bandwidth capabilities of fiber networks, ensuring the right infrastructure is in place in the passive plant is paramount. The level of densification 5G networks demand will necessitate a fiber network so prolific

14:30 – 14:50 Driving access network convergence through next-generation PON and SD-Access

Ryan McCowan, Director, Product Management, Adtran

As operators push more and more fiber deeper into the network to support a range of residential, enterprise and x-haul services, the need for access network convergence is greater than ever. By combining leading access technologies like NGPON2 with SDN-based programmability, operators are now able to build highly programmable and scalable converged access networks. This presentation will cover the use cases driving convergence and the best practices for implementing these converged, SDN-controlled access networks. 

14:50 – 15:10 Challenges and Solutions for an NG-PON2-based Fronthaul

Luca Valcarenghi,   Scuola Superiore Sant’Anna, Pisa, Italy

The New Radio Access Architecture (New RAN), as defined by 3GPP in TR 38.801, features the disaggregation of the next generation node B (gNB) into a Distributed Unit (DU) and Central Unit (CU). The distribution of functionalities between CU and DU impacts the characteristic, in terms of capacity and latency, that the CU-DU connection (i.e., the fronthaul) shall guarantee. This presentation shades some lights on the suitability and on the attentions to be taken when an NG-PON2 is utilized to carry fronthaul traffic.

15:10 – 15:30 The Effect of Virtualization on PON Architectures and Hardware

Ed Boyd, CTO and Cofounder, Tibit Communications       

Today’s PON systems are massively integrated and application specific systems that, in addition to the PON functions, contain multiple layers of switching and traffic management. PON systems are becoming virtualized and the impact on system hardware is subtle, yet significant. In this presentation we will compare the integrated and virtualized architectures and explore the advantages of virtualized PON.
