Smart Fiber Media Converter with Serial Port: A Practical How-To!

In scenarios such as industrial automation and security monitoring, long-distance transmission of network and serial port data is often affected by electromagnetic interference and limited by transmission distance. The E-link LNK-IMCRS1100-SFP mini industrial 100Mbps optical converter can perfectly solve this problem.Smart Fiber Media Converter with Serial Port: A Practical How-To!

This smart fiber media converter integrates Ethernet, optical fiber, and multiple serial ports, and thanks to its industrial-level protection and wide temperature range characteristics, it becomes the core equipment for industrial data transmission.

Product Definition

LNK-IMCRS1100-SFP is a rail-mounted 100Mbps media converter. It is equipped with RJ45 electrical ports, SFP optical ports, and integrated RS232/RS485/RS422 serial ports. It can simultaneously convert network signals and industrial serial port signals to optical fiber links, and is compatible with mainstream communication protocols. It is a multi-functional data transmission device specifically designed for harsh industrial environments.

Working Principle

The smart fiber media converter adopts a store-and-forward data processing mode. The Ethernet port receives 10/100M network data, and the serial port module collects signals from RS232, RS485 or RS422 devices. These two types of data are integrated by the internal circuit and converted into optical signals, which are then transmitted via an external SFP module through optical fibers. At the receiving end, the optical signals are restored to network and serial port signals.Smart Fiber Media Converter with Serial Port: A Practical How-To!

Multi-mode optical fibers can transmit data up to 2 kilometers, while single-mode optical fibers can reach up to 80 kilometers. Additionally, the built-in circuitry performs signal shaping, lightning protection, and electrostatic protection to ensure continuous and stable data transmission.

Installation and Usage

  • Hardware Installation: The equipment supports DIN rail installation and wall-mounted installation. A bracket for the rail is provided as standard, and wall-mount accessories are included with the device. Simply fix the device to a flat position on the control cabinet or the wall.
  • Wiring Connection: Connect a 12-48VDC DC power supply to the terminal block; connect the RJ45 port to a network cable, insert the SFP slot with a matching single-mode/multi-mode SFP module, and connect the serial port terminals to the RS232/RS485/RS422 terminal devices.
  • Power On and Debugging: After powering on, observe the PWR indicator light to confirm normal power supply. Based on the status of the FX, network port, and serial port indicator lights, determine whether the link and data transmission/reception are normal. The device supports automatic Ethernet negotiation and can work normally without additional configuration.
