Transforming Your Worksite and Office

A revolution in fusion splicing!

SumiCloud™ was developed by Sumitomo Electric as a cloud-based service using original in-house IoT technology to seamlessly share information and data from fusion splicing operations at the worksite. It allows project managers to monitor splicing progress and quality in real time right from the office. At the same time, operators in the field can connect to the dedicated smartphone app to manage their assets and splicing data, update their device's software, and receive maintenance support. As such, SumiCloud™ ensures the highest level of smart management for all sides of the splicing operation.
