4 Overview
Industrial networks are designed to connect and control devices, systems, machines, and other assets within the
industrial environment. With digital transformation, remote control machinery and sensors are deployed to automate
production, monitoring, and management. Industrial networks are incorporate facilities related to the Industrial business
including R&D centres, warehouses, administrative offices and customer service branches.
Industrial PON, is inheriting a mature PON technology from the residential access network, and enhancing it to include
functions required by the industrial customers. Industrial PON shall support high quality connectivity for
communication between sensors, devices, machines, and people within the industrial parks.
NOTE: For more detailed description of PON based industrial network see ETSI GR F5G 001 [i.1], ETSI
GS F5G 013 [1], ETSI GR F5G 007 [i.2] and ETSI GR F5G 021 [i.6].
The present document describes the typical industrial PON deployment scenarios, encompassing the architecture, the
key industrial functions and the interfaces of the industrial PON system. The PON based industrial network architecture
includes the management system, the OLTs, and ONUs used in industrial scenarios. PON based industrial network shall
comply with the industrial environmental recommendations.
In the present document, the network architecture, the functional requirements, the performance requirements, the
management and provisioning specifications for PON based industrial networks are specified.
5 Industrial scenarios and requirements
5.1 Overview
There are three deployment scenarios for PON based industrial networks, as described in ETSI GR F5G 007 [i.2]
(Industrial PON) and in ETSI GR F5G 008 [i.3] (Use Cases Release #2), namely:
1) The field data network which is primarily in the industrial environment.
2) The office network including sales, marketing, finance and managerial staff areas.
3) The surveillance network including internal and external video surveillance and sensors.
PON based industrial networks shall support the above three sub-networks within a single network infrastructure.
Network slicing is essential for the isolation of these sub-networks.
Smart network monitoring and management functions based on NETCONF/YANG and telemetry technology are
needed for smart operation and rapid service configuration in the PON based industrial networks.
5.2 Field Data Network
The primary application in PON based industrial networks is transport factory intra-plant industrial services. PON
serves as a connection and convergence network for the machines within the factory.
There are several industrial field level interfaces and protocols defined in the IEC 61158 series [3]. Therefore, the
ONUs in the industrial network need to be equipped with the corresponding physical interfaces and the built-in
protocol-related functions, or provide connectivity to existing industrial gateways, to support the communications
between the Power Line Communication (PLC), other industrial gateways, and production management systems.
Deterministic network transmission and high service availability are required for these field data network scenarios. The
PON based industrial network integrated with deterministic networking functions, shall support the configuration of
bounded transmission times, and various network protection schemes for the differential network resilience scenarios.
ETSI
13 ETSI GS F5G 022 V1.1.1 (2025-01)
Machine vision applications are being deployed in the production line, which require high bandwidth. High-resolution
images/video cameras are installed on the production lines to capture high-definition images or video streams for
further AI-based analysis and recognition, which quickly locate malfunctioning production and defective products.
These applications require very large upstream network bandwidth, with traffic flows in the order of tens of gigabits per
production line. XGS-PON [11] systems support symmetric 10 Gbit/s bandwidth, which satisfy these bandwidth needs,
and in future 50G-PON [i.18] will provide up to symmetric 50 Gbit/s bandwidth to further enhance the network
capabilities.
5.3 Office Network
PON based industrial network should support the transport of traffic from the office area of a factory for ®
internet/intranet surfing, telephony and Wi-Fi APs traffic. The applications and services in this scenario are similar to
the majority of services carried by PON system in the public access network.
The PON system need to provide Ethernet physical interfaces, and network functions for internet/intranet surfing
similar to the ONUs in the residential and business scenarios, and also support configuration and management for rapid
service configurations. XGS-PON [11] with 10 Gbit/s bandwidth satisfies the large bandwidth requirements in office
network.
5.4 Surveillance Network
Another important industrial network scenarios are the video surveillance networks and the environment sensing
networks around the factory.
PON ONUs shall support Power over Ethernet (PoE) functionality to provide both network connectivity and electricity ®
supply for remote video monitoring cameras. Other capabilities like Wi-Fi Access Point (AP), small cellular cells may
also be embedded to the industrial PON ONU to realize the data transmission for several kinds of sensors.
6 Industrial PON system architecture
The industrial PON system is part of the end-to-end F5G network architecture defined in ETSI GS F5G 024 [2], which
includes both the Customer Premises Network (CPN) and the Access Network (AN) segments.
NOTE 1: The aggregation network for Industrial PON scenario is for further study.
The industrial PON system provides service connectivity for the users and devices in the industrial area. The most often
deployed protocols used in the industrial scenarios shall be supported by the industrial PON system. The industrial
ONUs are ONUs specifically used in PON based industrial networks. These ONUs support industrial
interfaces/protocols and industrial scenario specific functions. They perform the Service Access Point (SAP) functions
and the OLTs performs the Service Processing Point (SPP) functions.
As the industrial PON system is the industrial factory intranet, the factory intranet may be self-contained depending on
the network scale, deployment scenario, and security considerations of the customers. The OLT
