The ETSI Industry Specification Group (ISG) on Fifth Generation Fixed Network (F5G) releases the specification titled "Fifth Generation Fixed Network (F5G); Specification for PON based Industrial Network".

Passive Optical Network (PON) is the dominant access network technology for operators all around the world and has been widely deployed in public access networks. It has the advantages of large bandwidth, low deployment cost, uses passive optical distribution network, carrier-grade quality and smart operation and maintenance capabilities.

The PON technology is the best fit also for industrial-grade applications with a few extensions. The extensions compared to residential FTTH deployments include deterministic networking functions, edge computing functions, the support of different environmental conditions, the support for industrial interfaces and protocol adaptation, supporting different topologies, and higher quality of service performance.

After F5G-A use cases, Proof of Concepts and first deployments, the publication of this standard accelerates the large scale deployment of PON based industrial networks for vertical industries, to satisfy the service requirements for the various industrial customers including the need for a lot of data transfer feeding AI training and decision making.

The specification was approved in the ISG F5G F2F#20 plenary meeting held in Jingdezhen, Jiangxi Province, China from November 12^th to 15^th 2024.

"Fifth Generation Fixed Network (F5G); Specification for PON based Industrial Network" specifies the network architecture, functional requirements, performance requirements, management and provisioning specifications for PON based industrial networks deployed in typical industrial application scenarios, and satisfies the requirements from industrial services.
