Breaking the Distance Barrier of Serial Communication | E-link China Industrial Multi-Protocol Fiber Optic Mode

Transparent Transmission, Unlimited Extension: Industrial Tri-Protocol Fiber Modem Enables 80km Lossless Transmission for RS232/485/422 Signals

Plug-and-Play Self-Adaptation, Supports DMX512 Stage Lighting Protocol, -40°C~75°C Wide-Temp Operation. A Revolutionary Long-Distance Solution for Industrial Control & Professional Lighting

In industrial automation, energy monitoring, and professional stage lighting, traditional RS232/485/422 serial communication protocols remain the backbone of control systems due to their stability and wide compatibility. However, their limited transmission distance (typically under 1.2km) and susceptibility to electromagnetic interference severely restrict layout flexibility in large plants, distributed energy stations, and major performance venues. To break this constraint, E-link China introduces the Industrial Multi-Protocol Fiber Optic Modem. This device innovatively transmits three mainstream serial signals over long distances via fiber optics with high immunity, supporting up to 80km on single-mode fiber, without altering existing serial device protocols or configurations. It is a revolutionary replacement for traditional copper cable solutions.

Core Value: A Triple Breakthrough in Distance, Immunity, and Ease of Use

1. Ultra-Long Distance Transparent Transmission:

   • Lossless Signal Extension: Supports full/half-duplex communication for RS232, RS485, and RS422, with data rates up to 2Mbps. Extends signal transmission distance from the kilometer range of copper cable to 2km on multi-mode fiber (MMF) and 80km on single-mode fiber (SMF),彻底解决 long-distance signal attenuation and distortion.

   • Fully Transparent & Self-Adaptive: Utilizes advanced self-adaptive technology, requiring no dip-switch or software configuration. The device automatically matches serial baud rate (0-2Mbps adaptive), data format, and parity for true "plug-and-play" operation.

2. Industrial-Grade Reliability & Professional Suitability:

   • Exceptional Environmental Tolerance: Operating temperature range of -40°C to 75°C. Built-in surge protection (15KV ESD) and over-voltage protection circuits ensure stable operation in harsh environments like substations and outdoor cabinets.

   • Built-in Professional Protocol Support: Specially optimized for high-speed serial data transmission supporting the DMX512 stage lighting control protocol, meeting the stringent requirements of large-scale performances and theme park lighting systems for long distance, high real-time performance, and superior noise immunity.

   • Easy Installation & Diagnostics: Supports DIN-rail and wall-mount installation with a compact design. The front panel features comprehensive status LEDs (Power, Fiber Link, Data Tx/Rx) for quick deployment and troubleshooting.
