  • REMOTE CONTROL: (1) DB9(F) connector accepts RS232 serial data commands.
  • CONTROLS: (8) Front panel pushbuttons allow selection of switch position.
  • DISPLAY: (8) Red LED's indicate switch position and power presence.
  • KEYLOCK: (1) Key operated front panel switch allows lockout of front panel pushbutton controls.
  • POWER: UL approved 100VAC-240VAC, 50Hz-60Hz wall mount power module supplies 12 VDC, 500 mA to the Model 6275. Has 2-prong, US, non-polarized plug.

  • WEIGHT: Approximately 8.7 lbs. (4.0 kg)


The Application drawing illustrates a ST Duplex COMMON port with access to any one of eight ST Duplex Fiber Optic ports connectors. The COMMON Device has access to one Device at a time. There is a front panel keylock to allow or inhibit front panel pushbuttons.  The Offline position is a valid state to preserve data isolation. The DB9 Remote port allows RS232 ASCII Serial Commands to remotely Control the unit.

  • Model 6275 is an example of a fiber optic switch with an internal OFF-LINE position and a keylock to lock out the front panel controls.

QuickSwitch® 6275 8-Position Switch w/Offline position, Keylock & RS232 Remote application


  • One ST duplex fiber optic port is able to access any one of eight ST duplex ports.
  • All fiber signals are switched via break-before-make MEMS-based mirror/prism switch technology.
  • The unit maintains last set position on power loss and continues to pass data or can be remotely controlled to revert to Offline position on power loss.
  • An Offline position is a valid state to preserve network data isolation.
  • Front panel pushbutton control.
  • Front panel keylock inhibits or permits pushbutton control.
  • When the front panel pushbuttons are inhibited via the keylock, only Remote commands are available.
  • When the front panel pushbuttons are permitted via the keylock, both pushbutton control and the Remote commands are available.
  • Remote RS232 commands allow user to control switch position, lockout front panel operations, obtain switch status, configure unit to revert to the Offline position in the event of a power loss, or maintain position on power down.
  • Front panel LED’s display present position and power status.
  • All 1 thru 8, and COM ports are ST Duplex, Multi-mode, 62.5/125 micron, and support a wavelength of 1300nm.
  • The fiber ports are configured per TIA/EIA-568-B.3, where the TX of the COM port is routed to the RX of the A/B ports and vice versa.

The QuickSwitch® 6275 ST Duplex Fiber Optic 8-Position Switch allows user to switch one COMMON port to any one of eight ST Duplex ports, with Remote access functionality.  The QuickSwitch® 6275 is enclosed in a 2U, full rack size, all metal black chassis designed to fit in a standard 19” rack.

The switch may be controlled locally via front panel pushbuttons or remotely from the DB9 female Serial Interface Remote port.
