The QuickSwitch 6288 is a microelectromechanical systems-based fiber optic mirror A/B switch designed by Electro Standards Laboratories. The device enables users to access two separate devices on ports A and B via connection through the common port by manual front-panel push button or over RS-232 serial data remote control of the switch. If power is lost, the 1300-nm switch will default to the A position and continue to transmit data. It supports a gigabyte data rate and is transparent to data format and speed. All fiber optic ports are duplex multimode ST with a fiber size of 62.5/125 μm. LEDs display the switch position and power status.
