Industrial RS232 RS485 RS422 Fiber Media Converter 80km

Product Specification

Model: LNK-277 Series

 Product Description & Overview

The Industrial RS232/RS422/RS485 Serial to Fiber Media Converter delivers robust protocol conversion

for mission-critical serial communications in demanding environments. This industrial-grade media converter

effectively transforms standard RS232, RS422, and RS485 electrical signals into optical fiber transmissions,

extending serial communication distances up to 2 kilometers over multimode fiber and 80 kilometers using

single-mode fiber optic cables. The unit's rugged steel enclosure provides superior protection against physical

damage and electromagnetic interference, making it ideal for harsh industrial applications where reliability is

paramount.

Engineered specifically for industrial automation and control systems, this fiber media converter completely

eliminates common communication challenges including electromagnetic interference, ground loop issues,

and lightning-induced damage that typically affect traditional copper-based serial connections. The wall-mount

compact design optimizes space utilization in control panels and industrial cabinets while maintaining full

compliance with industrial operating standards. The device supports transparent protocol conversion without

requiring configuration changes to existing serial equipment, ensuring seamless integration with PLCs, HMIs,

and other industrial control devices.

This versatile media converter finds extensive application across numerous industrial sectors including factory

automation, process control systems, transportation management, and energy distribution networks. The advanced

optical isolation technology provides complete electrical separation between connected devices, significantly

enhancing data communication security and reliability. With its wide operating temperature range and robust

construction, this solution offers industrial operators a reliable, interference-resistant serial communication

alternative that dramatically improves network stability while reducing maintenance costs associated with

traditional copper serial installations in electrically noisy environments.
