Cisco MFEFX1 - compatibele industriële SFP-transceivermodule met DOM - 100BASE-FX SFP 1310nm 2km DOM LC MMF

Network engineers upgrading legacy Fast Ethernet links in factories, warehouses, or outdoor cabinets often face harsh conditions and the need for reliable monitoring. The FS.COM MFEFX1-C compatible industrial SFP transceiver answers that call: it delivers 100BASE-FX connectivity over multimode fiber up to 2 km, with a wide -40°C to 85°C operating range and Digital Optical Monitoring (DOM) for real-time diagnostics. Fully MSA-compliant and hot-swappable, it drops into any Cisco MFEFX1-compatible port without downtime.

Key specifications

• Form factor: SFP (Small Form-Factor Pluggable)
• Data rate: 100 Mbps (Fast Ethernet, 100BASE-FX)
• Wavelength: 1310 nm FP laser
• Reach: up to 2 km on multimode fiber (MMF)
• Connector: LC duplex
• DOM support: Yes (Digital Optical Monitoring)
• Operating temperature: -40°C to 85°C (industrial grade)
• Power consumption: <1 W, 3.3 V supply
• Compliance: MSA, RoHS; hot-swappable
• MTBF: >500,000 hours

Why choose it

Unlike standard commercial SFPs, this module is built for industrial environments where temperature swings, vibration, and dust are common. Its DOM feature lets you monitor transmit/receive power, temperature, and voltage in real time, helping prevent failures before they occur. The 1310 nm wavelength and FP laser ensure stable performance over multimode fiber, while the LC duplex connector provides a secure, compact link. It is fully compatible with Cisco MFEFX1 and any MSA-compliant SFP port, making it a drop-in replacement or spare for existing networks.

Ideal use cases

• Industrial Ethernet in manufacturing plants, power utilities, and transportation systems
• Outdoor or unconditioned cabinets where temperature extremes are expected
• Upgrading legacy 100BASE-FX links without replacing switches or media converters
• Network monitoring and diagnostics in remote or hard-to-access locations
• Spare or replacement for Cisco MFEFX1 transceivers in enterprise networks

Good to know

This transceiver supports full-duplex operation and is hot-swappable, so you can install or remove it without powering down the switch. It is designed for multimode fiber with LC connectors; ensure your fiber plant matches. The industrial temperature rating means it can be deployed in environments from freezing cold to extreme heat, far beyond typical office conditions. For best results, pair with OM1/OM2 multimode fiber for 2 km reach; OM3/OM4 can also be used but distance may be limited by modal bandwidth. FS.COM provides a lifetime warranty and compatibility guarantee for this module.
