Industrial 1~4Ch RS232/RS22/RS485 Double-ring Fiber Media Converter
Industrial Double-ring Fiber Media Converter Overview
The LNK-GYS200 Series represents a robust industrial-grade fiber optic transmission
system engineered for mission-critical serial communications. This
advanced platform supports 1 to 4 channels of RS232/422/485 signal conversion and transmission over optical fiber, enabling flexible deployment
across multiple network architectures including point-to-point,
chain, star, and redundant ring topologies. Featuring self-healing
ring network protection with rapid fault recovery capabilities, the
system ensures continuous operation essential for industrial
automation and infrastructure monitoring applications.
By leveraging fiber optic technology, the series effectively
resolves traditional limitations of serial interface
communications—extending transmission distances while maintaining
high data rates without electromagnetic interference or ground loop
issues. The inherent electrical isolation of fiber optic
transmission provides built-in protection against lightning strikes
and power surges, significantly enhancing communication reliability
in harsh industrial environments. These characteristics make the
LNK-GYS200 particularly valuable for applications requiring high
security and data confidentiality, including power utility
automation, railway signaling systems, and industrial control
networks where communication integrity is paramount.
