Rugged, Flexible & Reliable Fiber Connectivity
RLH Industries EMC-22G-1 is an industrial Gigabit Ethernet media converter featuring three operating modes: Unmanaged Switch Mode, Redundant Fiber Backup Mode, and Dual Media Converter Mode. The multiple operating modes provide reliable network topology solutions for a variety of field applications, reducing system complexity and deployment costs.
Multimedia Functions
- Unmanaged Switch Mode – Operates as a 4-port unmanaged switch for simplified daisy-chain network expansion
- Redundant Fiber Backup Mode – Provides automatic link protection for highly critical networks
- Dual Media Converter Mode – Supports two completely independent links for traffic separation
The dual-rate 100/1000 SFP ports support multimode, singlemode, and bi-directional WDM fiber depending on the SFP used. The EMC-22G-1 operates on 12~48VDC and supports dual redundant power inputs with surge protection for uninterrupted operation. A built-in alarm relay provides power and link fault notification.
Designed for industrial applications, the EMC-22G-1 is DIN rail or wall mountable and hardened to operate in -40°C~+75°C, ensuring reliable performance in extreme environments.

Features
- 2 Gigabit RJ-45 & 2 dual-rate 100/1000Base-X SFP ports
- Supports Fiber Backup Mode, Dual Mode & Switch Mode
- Hardened to operate in -40°C~+75°C (-40°F~+167°F)
- Relay output for power and port link fault alarms
- LED indicators for Power, Mode/Function, SFP & Activity
- Supports 9k Jumbo Frames
- Dual DC power inputs (12~48VDC)
- DIN rail and wall-mountable
- IP-30 Aluminum Housing
