8-POSITION FIBER OPTIC ST DUPLEX APPLICATION, FRONT PANEL KEYLOCK, OFFLINE POSITION, RS232 REMOTE: 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.

A COMMON Fiber Optic Device is connected to the ST Duplex COMMON port with access to 8 other Fiber Optic Devices (Device 1 through Device 8), connected to the ST Duplex ports (Ports 1 through 8). There is an OFFLINE position which isolates data and preserves the network. The front panel Keylock in the OFF position locks out front panel pushbutton operations. A DB9 REMOTE port allows the user to remotely control the fiber optic unit via RS232 Serial data commands.



  • One ST duplex fiber optic port is able to access any one of eight ST duplex ports.
  • All fiber optic signals are switched via break-before-make MEMS-based mirror/prism switch technology and supports Gigabit data rates.
  • All ports, 1 thru 8 and COM are ST Duplex, Multimode, 62.5/125 Micron, 1300nm.
  • Remote RS232 ASCII commands that allow the user to control switch position, and obtain switch status.
  • Front panel pushbutton control.
  • Front panel LED's display the switch position and power status.
  • Front panel keylock inhibits or permits pushbutton control.
  • An Offline position is a valid state to preserve network data and data isolation.
  • User can configure the switch to either maintain its position and data pathways on power failure or to revert to the Offline position during power failure.
  • Municipalities, schools, government: This product is on GSA Schedule!

The QuickSwitch® 6275 ST Duplex 8-position Fiber Optic Switch with Remote Serial Control allows the user to switch one Common ST Duplex port to any one of eight ST Duplex ports, or to be switched to an Off-Line position isolating all ports from each other.  The system affords local and 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.

Remote access can be accomplished by RS-232 commands sent via the Remote Serial Port.  Users can remotely monitor status and control switch functions.

This high-quality network switch is available to city, state, and federal government purchasers at a discounted price and favorable payment and shipping terms via GSA Schedule GS-35F-0286V.  

(Cat No 517277) CE, RoHS, and UL listed table mount power module, 100 VAC / 240 VAC, 50Hz/60Hz for use in place of standard power module that is included with the unit.  Ideal for international applications.
