USB Extender: Simplifying USB Extension Over CAT5 Cables
Extenders are used for extending the distance between source and peripheral device. However, the cables used to secure the connections sometimes hinder the distance at which the devices can be placed. The USB distance barrier can be eliminated by using a USB Extender. With the use of this device, the distance between the host computer and the extended peripheral can be around 150 feet. These extenders make use of Cat5 cables for securing the connection between the transmitter and receiver. Additionally, these cables save space and avoid clutter which is caused by standard cables. There is also a fiber optic version of this extender that allows for transmission at even greater lengths. This high-end version makes use of single mode or multi mode fiber cables, increasing the distance of usage to up to 10km.
Enhancing the Signal Transmission Efficiency via USB ExtenderSimple and economical to use, these extension units are available as a point to point or 4 port hub extender. They allow computers to be placed at secure locations in environmentally controlled conditions. The USB 2.0 Extender is a more enhanced version and is patented by Icron’s Extreme USB technology. Compliant with USB 1.0, 1.1 and 2.0 specifications, this extender works well with Windows, Mac-OS, Linux and Sun. I/O devices, printers, scanners, web cams, hard drives, flash drives and mp3 players are examples of devices supported by this extender. The main features of this device is the ability to transmit USB 2.0 technology at distances up to 330ft. Operating with plug and play functionality, no additional software or external power adapters are needed.
Equipped with the standard agency approvals such as FCC and CE Class A certification, it also has LEDs which indicate the link performance status. A 5V DC adapter at the remote unit provides standard 500mA of power. Another model of extender which is in demand is the KVM Extender. Among the various features of this extender that make it popular are: providing dual user access by connecting peripherals locally and remotely; allowing a computer to be connected at both the transmitter and receiver, thereby acting as a KVM Switch; extension of peripheral devices up to 1000ft (300m) away; and requiring no software.
These extenders follow the DDC; DDC2; DDC2B protocols and support VGA, SVGA, and Multisync monitors. Equipped with the ability to sense the distance to the system and automatically adjust the signal levels accordingly, these extension units provide crisp and clear images with no data loss. They maintain high quality VGA or DVI video resolutions and some versions are available with optional stereo audio, RS232 or infra red control. In applications where peripheral devices need to be operated remotely, a USB Extender plays a key role. Digital signage, financial, commercial or government arenas all make use of this hardware device.
