EL900-A-M-1-A Industrial Fiber Media Converter (ST) 20km

EL900-A-M-1-A Hardened Single-Mode Fiber Media Converter

10/100 Mbps Ethernet to 100BASE-FX single-mode fiber, ST connectors, up to 20km.

Operating temperature: −40 to 75°C (−40 to 167°F).

The EtherWAN EL900-A-M-1-A extends copper Ethernet connections over single-mode fiber for industrial networks. Its fixed 1310nm fiber interface supports links up to 20km, connecting equipment across larger facilities and remote installations.

Built for harsh environments, it combines an aluminum enclosure with redundant power support, fault monitoring, and DIN-rail mounting.

Key Features

• 20km fiber connectivity: Single-mode ST interface for long-distance Ethernet links.
• Fast Ethernet conversion: One 10/100BASE-TX RJ45 port and one 100BASE-FX fiber port.
• Hardened operation: Supports demanding temperatures and resistance to shock, vibration, and electrical noise.
• Link Fault Pass Through: Passes a link failure to the opposite interface so connected equipment can detect the interruption.
• Power and link alarms: Alarm relay provides notification of monitored failures.
• Protected power input: Overload current and reverse polarity protection.
• Industrial installation: DIN-rail mounting kit included, with optional panel mounting.

Applications

• Connecting remote equipment across industrial facilities.
• Extending Ethernet to transportation and roadside cabinets.
• Linking utility monitoring and control equipment.
• Connecting surveillance networks over long fiber runs.

Common Questions

How does this differ from the EL900-A-C-1-A?
Both use ST connectors. The EL900-A-M-1-A supports single-mode fiber up to 20km, while the EL900-A-C-1-A supports multimode fiber up to 2km.

Can it be installed outdoors?
It can operate inside a suitable protective outdoor cabinet. The IP30 housing requires protection from rain and moisture.

Is a power supply included?
No. Use a compatible external DC power supply, such as either option below.
