On June 28, Changsha Metro Line 1 North Extension Phase I officially commenced operations, marking the debut of the tenth operational line (section) in Changsha’s rail transit network. Huafei Technology’s photoelectric converters were successfully integrated into the line’s communication systems, ensuring stable and efficient data transmission to support the project’s successful launch. The company has consistently contributed to Changsha’s metro development, including Line 6’s PIS system, access control systems, and now Line 1’s North Extension communication infrastructure.

Technical Breakthroughs

Huafei’s photoelectric converters enhance data transmission reliability by converting electrical signals to optical signals and back, effectively mitigating interference and ensuring accuracy and real-time performance. This not only strengthens the stability of passenger information systems but also elevates rider experiences.

Huafei Technology takes pride in contributing to Changsha Metro Line 1 North Extension Phase I. Through continuous technological innovation and exceptional service, the company remains committed to advancing urban rail transit development.
