The Gefen EXT-USB-400FON is an Optical 4 Port USB 2.0 Hub which supports all USB 2.0 devices, extending to 1640 feet (500 meters) away from the USB source. The receiver end is also a four USB 2.0 hub. By using fiber optic cables, the new Gefen USB 400FO extends a long distance from the location of a computer. It provides an EMI interference-free solution for USB extension work.

How It Works:

The USB 400FO sender unit is connected to the source using the supplied USB short cable. The USB peripheral(s) are connected to the receiver unit at the extended side. Two LC-terminated fiber optic cables are used to link the sender to the receiver.

Note: This equipment is a new version of the discontinued part number, EXT-USB-400FO, and can provide outstanding extension facilities for anything that requires a USB connection over a distance, such as a USB camera or USB hard drive.

Question: Need nominal power requirement for remote hub (not how much it can source, but how much to operate the link). Nominal watts and/or current at nominal voltage. Thanks!
Answer: Thank you for your inquiry and your patience. We have finally received information back from the manufacturer regarding the power consumption of the remote receiver. According to our contact the power consumption for the receiver without external devices is 5V at 600mA (3W).
