Industrial Fiber Optic Converter 4 Channel RS232 422 485 Redundant Ring Network

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.
