QuickSwitch® 6270 AB Fiber Optic Network Switch enables a device connected to the COMMON port to access either of two separate Fiber Optic networks via SC duplex ports. Model 6270 utilizes MEMS-based (Micro Electro Mechanical System) multimode switches. The switch position of the Model 6270 can be controlled manually via a front panel pushbutton or remotely using the rear-panel RS-232 serial port. Once connected to the remote port, the computer can use any common terminal emulation software to manipulate the controls and monitor the switch position.
