Portable fiber link

The STARTECH US1GA30SFP is a USB 3.0 to SFP network adapter that adds a Gigabit fiber port to laptops and tablets through a standard USB-A socket. It targets mobile workers and technicians who need secure, long-distance connectivity without opening a chassis.

Gigabit ceiling and thermal window

The adapter conforms to IEEE 802.3z 1000BASE-SX/LX and IEEE 802.1Q VLAN tagging, fixing the maximum throughput at 1000Mbps regardless of the SFP module fitted. Operation is rated from 0 to 60 Celsius, while storage tolerates -10 to 70 Celsius and 5 to 90 percent relative humidity.

Compact external build

The housing measures .80 by 2.20 by 10.20 inches and weighs .22 lb, so it travels easily in a kit bag. A single USB 3.0 Type-A female connector draws power and data, while the open SFP cage accepts multi-mode or single-mode transceivers for the required reach.

Questions about this item

How do I choose between the multi-mode and single-mode SFP modules for this adapter?

The adapter accepts any standard SFP transceiver; select a multi-mode module for short-range links or a single-mode module for long-distance runs, matching the module to your fibre type.

What does the 1000 Mbps rating deliver when the adapter is plugged into a USB 3.0 port?

The USB 3.0 interface provides enough bandwidth for full gigabit throughput, so the link runs at 1000 Mbps without bottleneck.

Which SFP standards does the slot support and what distance limits apply?

The slot follows IEEE 802.3z 1000BASE-SX and 1000BASE-LX, so distance is determined by the chosen SFP module rather than the adapter itself.
