Industrial Serial to Fiber Converter 80km Range RS232/422/485 Wide Temp Surge Protection

Industrial Serial to Fiber Converter 80km Range RS232/422/ 485 Wide Temp Surge Protection

Overview

The LNK-277 Series represents a robust industrial-grade protocol conversion system, specifically engineered to transform standard serial communication interfaces into optical fiber links. This advanced media converter supports multi-protocol operation including RS-232, RS-422, and RS-485 serial standards, enabling reliable long-distance data transmission across extended network infrastructures.

Through sophisticated fiber optic conversion technology, the system achieves exceptional transmission ranges - supporting distances up to 2 kilometers using multimode fiber and extending to 80 kilometers with single-mode fiber configurations. This significant extension capability makes it ideal for industrial automation applications where electrical noise immunity and data integrity are critical requirements.

Housed in a compact yet durable industrial-grade steel enclosure, the converter features wall-mount design flexibility while maintaining ruggedized protection against harsh environmental conditions. The metal casing provides superior EMI/RFI shielding and thermal management, ensuring stable operation in demanding industrial settings such as factory floors, utility substations, and transportation infrastructure.

Particularly suitable for SCADA systems, industrial control networks, building automation, and security monitoring applications, this media converter delivers complete electrical isolation between connected equipment, effectively eliminating ground loop issues and providing lightning surge protection for connected serial devices.
