S7 fusion splicer

A fiber fusion splicer is a device used to join two optical fibers. It works by generating an electric arc that melts the fiber ends, creating a low-loss, high-strength permanent connection that ensures efficient signal transmission.

Característica

Six-motor fiber core alignment system achieves loss as low as 0.01dB with a fusion time of just 6 seconds, meeting stringent backbone network requirements.
7-second fast fusion (6 seconds in FAST mode) and 18-second heating significantly reduce project timelines.
Rubber protective cover + high-strength chassis provide drop, dust, and rain resistance, making it suitable for outdoor and harsh environments.
5200mAh high-capacity lithium battery supports 240 operations; compact body facilitates portability, meeting fieldwork demands.
Built-in storage for 2000 fusion records, 41 preset fusion modes, and support for system self-diagnosis and data management.
The splicer features built-in Chinese and English interfaces, with additional languages available
