Serves as a port doubler. This adapter allows the transmission of two separate LAN signals over a single network cable. One adapter is required on each side of the cable. Limitation: The original network cable must be fully populated. The maximum transmission rate is 100 MBit/s per port. Gigabit cannot be transmitted since all 8 wires of the original cable would be needed for that. Protected against external interference, the robust metal housing ensures the best shielding properties and guarantees reliable signal transmission. This shielding provides protection against external disturbances such as parallel power cables and ensures interference-free data transmission. Gold is key: The gold-plated connectors protect against corrosion and also increase conductivity. This ensures fast and durable transmission of your data.
