USB2.0 Fiber Extender 20KM Over CAT6 Cable 4 Port USB Extension Hub RJ45 100m USB Sharing Switch For keyboard mouse PC Computer. Introduction: Nsendato of USB2.0 Extender via single CAT-5E/6 cable to extend the USB2.0 signal up to 100meters, or via single fiber cable to extend the USB2.0 signal up 20KM. The extender support low speed, full speed, high speed USB signal. When transmitting the USB data, the extender also can support low speed full duplex data transmission. In order to make sure the low speed transmission stable, the full duplex speed should be not higher than 1Byte per second. In the meanwhile, the computer can be started up, shutdown, or reboot via the extender in a long distance at the Receiver. In the condition that the computer can not be touched, the extender will be a superb choice. Feature: Compact size, One pair as a full functional module, no need of settings. Via single CAT-5e/6 cable or fiber cable to achieve long distance transmission. CAT-5e/6 follow the standard of IEEE-568B. Transmission speed up to USB2.0 high speed. When transmitted via CAT cable, the yellow LED(Conn), indicates waiting for connection if flashes slowly, indicates connection successfully when flashes fast. When transmitted via CAT cable, the green LED(Status), indicates data communication normally between the Sender and Receiver if it flashes. Specification: CAT cable transmission distance:100 meters.
