In a world first, the Q502S introduces a fiber type detection feature, enabling it to distinguish between MMF and SMF fiber types and ensure the correct splicing program is used.

SumiCloud™ adds wireless LAN connectivity to the Q502S with a suite of cloud-based productivity services via a smartphone app. SumiCloud™ includes a preventative maintenance feature, over-the-air firmware updates, and the ability to create and send job reports to the cloud. A web browser-based management interface allows managers to review reports and fusion splicer performance, and remotely lock units in case of theft.

The Q502S's lightweight and compact body has a large touchscreen with multi-touch functionality for a familiar user interface that makes it easy to use.


The Q502S carrying case includes an ergonomic work tray. The fusion splicer can be used on the tray as soon as the case is opened, allowing users to start working immediately. The Q502S improves work efficiency and reduces installation/construction time in the field.
