1. Mission Statement:

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 Director: Marta Seda, Calix

2. 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.

3. 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 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:
    • G-PON & XG-PON & XGS-PON ONU Conformance Test Plan
    • XGS-PON TC Layer Test Plan
    • NGPON2 Test Plan
    • PMD Layer Test Plan.

Project Stream

 Description

PS Leadership

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.

GPON Interoperability Test Plan

WT-255 Issue 2 is a BBF GPON/XGS/XG Interoperability test plan that describes a series of test cases that may be used to verify the interoperability of an OLT and ONU pairing according to the functional requirements of BBF TR-156, TR-280, and ITU-T G.988.  It is intended that these test cases be used with an ONU already awarded the BBF.247 GPON ONU Certification and an OLT known to use standardized OMCI managed entities to implement the configuration under test.
