Why This Ethernet Media Converter Fiber Matters for Your Setup
When you need to stretch a copper network beyond the usual 100-meter limit, an ethernet media converter fiber like the CF104 gives you a straightforward path. Instead of ripping out existing Cat5 cabling or adding expensive switches, you plug this unit in and bridge twisted‑pair segments with single‑mode or multi‑mode fiber – up to 120 kilometers. That means you can connect a remote warehouse, a parking lot camera bank, or a campus building without signal degradation or electrical noise pickup.
This is not a managed device with a steep learning curve. It’s an unmanaged, plug‑and‑play converter. IT admins and small‑business owners appreciate that there’s zero configuration: power it on, connect your RJ45 devices, plug in the fiber, and traffic flows. The metal casing acts as a heat sink, letting the unit run cool even in a dusty closet or a factory floor with ambient temperatures up to 60°C.
We’ve designed the CF104 with real‑world workloads in mind. All four Ethernet ports auto‑negotiate speed (10/100 Mbps) and duplex mode, and they support auto MDI/MDI‑X so you don’t need crossover cables. The 2K MAC table handles common office or surveillance VLANs without issue, and the 2048‑byte jumbo frame support improves throughput for large data transfers like video streams or backups.
Who benefits most? System integrators deploying IP cameras over long distances, facilities managers connecting distant access‑control panels, and network administrators extending a corporate LAN to an outbuilding. The compact size (113×83×26 mm) fits on a desktop or mounts on a wall using the included brackets, keeping your wiring neat.
- 1x 100Base‑X SC fiber port (single‑mode or multi‑mode, distance up to 120 km)
- 4x 10/100Base‑TX RJ45 ports with auto‑negotiation and MDI/MDI‑X
- 2K MAC table, 768 Kbit frame buffer, store‑and‑forward switching
- Bandwidth 1 Gbps, packet forwarding rate 0.75 Mpps
- Metal housing, natural cooling – no fan noise or dust intake
- Power input DC 5‑12 V, consumption < 3 W – low operating cost
Whether you’re upgrading a legacy coax‑to‑fiber link or building a new point‑to‑point connection, this ethernet media converter fiber delivers the reliability you expect from a purpose‑built industrial‑grade device, without the complexity of a full‑blown managed switch.
