USB 3.0 to 1000Base-SX fiber adapter

The Transition Networks TN-USB3-SX-01(LC) adds a Gigabit Ethernet fiber port to any device with a USB 3.0 socket. It is aimed at laptop, notebook and tablet users who must reach a fiber-based network where copper or wireless links are unsuitable.

LC connector for 1000Base-SX multimode fiber

The single specification that decides compatibility is the LC duplex interface running 1000Base-SX over multimode fiber. Only networks terminated with matching LC 1000Base-SX optics will link; other fiber types or connector styles will not work.

Bus-powered with no external supply

The adapter draws all power from the host USB 3.0 port, consuming 5.60 oz of weight and measuring 2.1 by 12.3 inches in its desktop form factor. No separate power brick is required, so acoustic noise is limited to the host system alone.

Questions about this item

How does the 1000 Mbps fiber link actually perform when plugged into a USB 3.0 port on a laptop?

The adapter presents a full Gigabit Ethernet connection over optical fiber, so the laptop sees a standard 1000 Mbps network interface without needing an internal fiber card.

What does the USB 3.0 interface limit in everyday use?

The USB 3.0 host connection provides enough bandwidth for the 1000Base-SX link, so the fiber port runs at line rate without being bottlenecked by the bus.

Will the 2.1 inch by 12.3 inch desktop unit fit on a crowded desk beside a laptop?

At 2.1 inches wide, 12.3 inches deep and 5.60 ounces, the black desktop adapter sits unobtrusively next to a laptop and draws power from the USB port.
