Industrial Serial to Fiber Converter

Introduction

E-link provides industrial serial to fiber converters specifically designed for reliable long-distance transmission of RS232, RS485, and RS422 signals over optical fiber. These converters are widely used in industrial control, automation, lighting control (DMX512), and outdoor communication systems where electrical noise, distance limitations, and environmental stability are critical concerns.

Our industrial serial converter portfolio focuses on fiber-based serial communication, offering both SC fiber optic modem and SFP-based modular designs to support flexible industrial deployments.

What Is an Industrial Serial to Fiber Converter?

An industrial serial to fiber converter enables serial communication protocols—such as RS232, RS485, RS422, and DMX512—to be transmitted over optical fiber instead of copper cabling.

By converting electrical serial signals into optical signals, these devices allow:

  • Extended transmission distance (up to 80 km)
  • Immunity to electromagnetic interference
  • Stable operation in harsh industrial and outdoor environments

E-link industrial serial to fiber converters are designed for industrial systems where legacy serial devices must operate reliably over long distances.

Key Features

E-link industrial serial to fiber converters are engineered for demanding industrial applications:

These features ensure stable serial communication in electrically noisy and outdoor deployments.

Typical Industrial Applications

Industrial serial to fiber converters are commonly used in:

  • Factory automation and PLC serial communication
  • DMX512 lighting control systems
  • Power substations and energy monitoring
  • Intelligent transportation and signaling systems
  • SCADA and remote serial device monitoring
  • Outdoor and long-distance industrial communication links
  • CCTV or PTZ camera systems

Fiber-based serial transmission improves distance, stability, and resistance to interference in these applications.

These converters are commonly deployed together with industrial managed Ethernet switches in PLC and SCADA networks.

Serial to fiber converters are commonly mounted on DIN rails inside industrial control cabinets to support stable long-distance communication.

Serial Communication & Industrial Networks

Although modern industrial networks increasingly rely on Ethernet, many critical systems still use serial protocols for control and monitoring.

Industrial serial to fiber converters allow these serial devices to operate reliably alongside industrial Ethernet switch infrastructures, enabling hybrid industrial networks without replacing existing equipment.
