EtherWAN EL100T Industrial Fiber Media Converter

EL100T is an unmanaged industrial media converter launched by EtherWAN, realizing bidirectional conversion between 10/100BASE-TX copper Ethernet and 100BASE-FX fiber optical network. It adopts ST/SC fiber interface, supports multi-mode fiber transmission up to 2km, and built-in LFPT link fault pass-through function to synchronize fault signals between optical and electrical ports for stable industrial long-distance communication.

This rugged industrial transceiver is widely used as maintenance spare for legacy DCS, PLC and factory automation systems. It supports DIN rail mounting, wide-temperature operation and dual redundant DC power supply with reverse connection protection. All-metal shell provides electromagnetic shielding to eliminate interference from inverters and large motors in harsh industrial sites.

Core Functions

• Realize mutual conversion between twisted-pair electrical signal and optical fiber signal, break distance limit of ordinary Ethernet cable transmission.
• LFPT fault linkage function automatically cuts off opposite port link when one side fails, helping DCS host quickly locate broken network links.
• Full galvanic isolation between optical and electrical ports eliminates ground loop interference, avoiding communication packet loss in heavy industrial workshops.
• Auto MDI/MDIX RJ45 port supports straight/cross network cables, plug-and-play without complicated configuration software.
• Dual redundant power design prevents single power supply failure from interrupting production control network data transmission.
• Compact DIN rail structure saves cabinet space, quick disassembly and replacement without shutting down the whole automation control system.
