Panel I: Next Generation Access Network

Wednesday, 11 March
11:15 - 12:45
Expo Theater I

Moderator: Julie Kunstler, Principal Analyst, Network Infrastructure and Software, Ovum, USA

Panel Description:

Access networks are continuing to evolve to support more bandwidth and lower-latency applications. Several operators are moving towards a "universal" access network, combining different traffic types onto a single access network. Other operators follow more traditional paths for wireline access network upgrades, such as next-gen TDM-based GPON and EPON. Some cable operators have plans to deploy HFC-based Full Duplex DOCSIS, while others are looking for alternatives to the node + 0 architecture required with Full Duplex. Still other operators are looking at 5G as a competitive solution to fixed/wireline broadband access. 

This panel will present and discuss case studies of next-gen access deployments covering telco operators, cable operators and mobile network operators.

Integrated ODN and Broadband Anyhaul Transport for All Customer Segments by Universal Next Generation PON

As Telkom Indonesia (TI) deploys the transport infrastructure for all customer segments (residential, enterprise and mobile Xhaul), we are facing the challenge of ROI by optimizing cost of FO deployment and faster network monetization. On the other hand, in technical aspects, we also have big homework to fulfill future requirement services for all segments such as high performance 5G technology readiness, higher speed symmetrical bandwidth broadband, and access service convergence. To anticipate this, Telkom Indonesia have introduced network strategy deployment of integrated optical distribution network (i-ODN) and broadband anyhaul transport to address such challenges in order to optimize rolling out future proof converged fiber network. We are fully exploiting the capability of universal Next Generation PON from several PON technology owners by doing some trials and specifying the specific requirement for key future network requirement such as latency, bandwidth, slicing capability and time synchronization clock. The whole presentation will address comprehensively about these issues.
