EtherWAN EL1142-20B, IEC 61850-3/IEEE 1613 Hardened 2-Port 10/100BASE-TX to 2-Port 100BASE-FX Media Converter

The EL1142 series provides two independent media conversion paths between 2 x 10/100BASE-T and 2 x 100BASE-SX-LX fiber. Similar to the EL1141 series media converter, the EL1142 includes the hardened construction and high performance needed for mission critical applications, including power substation automation. However, the EL1142 series offers twice the port density in the same housing dimensions, providing greater flexibility and requiring less space for installation. EtherWAN - "When Connectivity is Crucial." This product is discontinued as of 27th March 2026.

Highlights

• Higher Port Density: Two independent media conversion paths in a compact housing
• EN 50121-4 Certification: Designed and tested for railway environment applications
• IEC 61850-3/IEEE 1613 Certification: Meets standards for application in power substation automation
• Link-Fault-Pass-Through (LFPT): Provides constant monitoring of the links connected to the media converters; if a copper link fails, the media converter will pass the fail state on throughout the link, disabling the fiber link and the copper link on the opposite end
