The latest working group to be set up under the auspices of the Telecom Infra Project (TIP) is called Open FAN (fixed area networks) and is led by Telefónica, TIM and Vodafone, three of the operators that are already prominent in Open RAN. Open FAN aims to define common interfaces between optical line terminals (OLTs) and optical network terminals (ONTs), at either end of the fiber connection, as well as standardized integration with SDN controllers. That would mirror the work of Open RAN on common fronthaul interfaces between radio units and basebands. “The disaggregation of OLTs represents a valuable opportunity to broaden the telecom supply chain, which we’ve seen has become more important than ever during recent times,” said Paolo…
