The QLink-3000 family of short range modems provides high-speed data access over single-pair copper wires. It can transmit data with rates up to 2304 kbps (2048 kbps for model with single E1 port) for up to 7.6 km (on 26 AWG cable). Using lower guage copper wire may allow you to attain greater distances.

Models with two data ports includes multiplexer and allows to transmit two independent data streams over single cooper pair.

The QLink-3000/E1 modem can be DC powered.

The device setup and all diagnostics options are controlled from the special supervisory port (asynchronous RS-232, 9600, 8N1) or from remote device.

The device has an upgradeable firmware.

Currently available models are listed in Prices. Please, contact technical support if you are unsure which model to choose.
