Mission Statement:

Excerpt

To define the requirements and data models for deploying Broadband Forum network architectures in fiber access technologies so as to accelerate deployments and ensuring interoperability.

Work Area Directors: Marta Seda, Calix; Samuel Chen , Broadcom

Business Impact:

This Work Area's focus along with the Physical Layer Transmission area is on both cost savings and acceleration of time to market. Standardized interoperability and certification create a trusted base of equipment and services without which significant investments in time and resources can cause years of delay and in-service failures that impact revenue and credibility. Interoperability provides invaluable intelligence as feedback to both developers and implementers of new products and services. As the move to virtualized devices with non-deterministic functions and performance becomes a reality, the need for interoperability testing, data models, and reference configurations will become critical.

Scope:

The FAN Work Area has the following main areas of responsibility:

  • Specification of PON related requirements.  These projects include:
    • Architecture & Technical Requirements for PON-based Mobile Backhaul networks
    • Multi-wavelength PON Inter-Channel-Termination Protocol Specification

    • Multi-service Broadband Network Architecture and Nodal Requirements in the context of PON 

  • Specification of PON NETCONF/YANG data models, test plans and certification for the defined YANG modules
  • Specification of PON test suites used to verify the interoperability of the fiber access specific portions of the network.  These projects include:
    • GPON & XG-PON1 ONU Conformance Test Plan
    • XGS-PON TC Layer Test Plan
    • NGPON2 Test Plan
    • PMD Layer Test Plan.

Interoperability and Test

Interoperability project stream is dedicated to PON system interoperability of telecom services over multi-vendor and multi-carrier inter-connections.  The Interoperability project stream has also added OLT NETCONF management interoperability between OLT NETCONF server interfaces and third-party NETCONF clients such as an SDN controller. 

 

Interoperability and test project is responsible for creating test cases documents for vendor certification and conformance.  Both vendors and operators benefit from these documents as they describe agreed-upon use cases to support.  Being able to exchange information between devices and management applications is crucial for the modern economy.

PON Abstraction Interface for Time-critical Applications

For flexible and agile service adaptation at a low cost in the next-generation optical access system, a new system architecture, which is based on SDN/NFV technologies, should be required. The most promising way to pursue the new architecture is disaggregating PON functions to functional modules with open interfaces.  The project propose a new work item to progress the architecture further by specifying a PON abstraction interface for time-critical processing functions, e.g. Dynamic Bandwidth Assignment (DBA), which is not covered existing BBF documents and on-going projects.

WT-423PMD Layer Test Plan

Operators that plan to use ITU-T XG(S)-PON (with or without XG-PON), and NG-PON2 requested the FSAN and BBF Groups to document a PMD (Physical Media Dependent) layer test plan for Conformance Events.  Executing these test cases as part of a multi-supplier test event will help OLT and ONU's implementation of the specifications operate as a functional system.

Multi-wavelength PON Inter-Channel-Termination Protocol (ICTP) Specification

NG-PON2, specified in ITU-T Recommendation series G.989, is a multi-wavelength PON system which includes in its scope an additional interoperability dimension in comparison with the earlier

PON systems: one that applies between the OLT channel terminations (CTs) within a single NGPON2 system. The NG-PON2 CTs must exchange information related, among other functionalities, to channel profile configuration and status sharing, ONU activation, ONU tuning, rogue ONU mitigation. OLT channel termination interoperability allows diversification of suppliers of the TWDM and PTP WDM NG-PON2 subsystem, as well as the suppliers of the TWDM CTs for business and residential applications. 

OLT channel termination interoperability is also instrumental in the case of co-operative multi-operator environments, where different operators share the same ODN each using only a subset of available NG-PON2 wavelength channel pairs. This technical report defines the requirements of the Inter-Channel-Termination Protocol (ICTP), which is used to exchange such information between CTs, enabling inter-vendor NG-PON2 interoperability

XG(S)-PON TC layer IOP Test Plan

WT-309 Issue 2 defines a set of test cases whose purpose is to verify interoperability between an XG-PON or XGS-PON  OLT and a BBF.247 certified ONU. These test cases address the Transmission Convergence (TC) sub-layer (G.987.3 [6], ITU-T G.9807.1 [8] Annex C). Executing these test cases as part of a multi-supplier test event will help OLT and ONU's implementation of the specifications operate as a functional system.
