The ComNet CNFE2004M1A is a compact, industrial-grade 2-port 10/100 Mbps Ethernet switch and WDM fiber optic media converter designed for harsh environment deployments. Featuring two 10/100Base-TX RJ-45 copper ports and one 100Base-FX WDM SC multimode fiber port (Channel A), this module transmits network traffic over a single optical strand, reducing cabling infrastructure costs.

Built in a mini-size hardened aluminum enclosure with integrated wall-mount flanges, the CNFE2004M1A operates reliably under extreme temperatures ranging from -40°C to +75°C. DIP-switches on the front panel allow easy configuration of Link Fault Extension (LFE) and operational modes without requiring software management.

Key Features

• Dual Copper Ports: 2 × 10/100Base-TX RJ-45 ports with Auto-Negotiation and Auto-MDI/MDIX.

• Single-Strand Fiber Technology: 1 × 100Base-FX WDM SC multimode optical port (Channel A).

• Industrial Hardened: Wide operating temperature range (-40°C to +75°C) for tough indoor/outdoor cabinet installations.

• Plug & Play / DIP-Switch Control: Configurable Link Fault Extension (LFE 1 / LFE 2) and MUX/DEMUX modes via physical switches.

• Flexible Power Input: 8–24 VDC or 12–24 VAC via 2-pin removable terminal block connector.

• Compact Mini Form Factor: Integrated mounting ears for direct surface/wall mounting.
