Dual-rate copper-to-fiber transceiver

The Transition Networks SGFEB1040-330-NA is a standalone media converter that bridges two 10/100/1000Base-T copper ports to two 1000Base-X SFP slots. It enables network managers to extend Gigabit Ethernet links over fiber while preserving existing copper endpoints. The unit accepts AC power and can be mounted in a rack, on a wall, on a rail or on a desktop.

Suited for copper-to-fiber links

This converter suits installers who need to connect copper switches or servers to fiber uplinks across campus or building backbones. It supports dual-port conversion in a single 1U-high chassis measuring 3.3 inches wide by 4.8 inches deep. Buyers who require managed switching functions, PoE injection or speeds beyond Gigabit Ethernet should consider a different product class.

Two fixed copper ports and two open SFP cages

The decisive specification is the port arrangement: two 10/100/1000Base-T RJ-45 ports paired with two empty SFP expansion slots. The SFP cages accept any standard 1000Base-X transceiver, so the exact fiber type and reach are chosen at deployment. No other port counts or media types are available on this model.

Questions about this item

Should I pick the single or dual SFP version for two fiber links?

The SGFEB1040-330-NA includes two SFP slots, so one unit handles both fiber connections without needing a second module.

What does the 10/100/1000Base-T rating deliver on my copper runs?

Each RJ-45 port auto-negotiates at 10, 100 or 1000 Mbps over twisted pair, giving full gigabit throughput on standard Cat5e or better cable.

How does the SFP interface limit distance and speed in practice?

The two SFP slots accept 1000Base-X modules, so maximum reach and wavelength depend on the specific transceiver you install in each slot.
