LC DUPLEX A/B/C/D/OFFLINE APPLICATION WITH DB15 CONTACT CLOSURE REMOTE: Diagram illustrates a COMMON device connected to the LC Duplex COM port allowing access to the LC Duplex ports, A, B, C, or D. In addition to selecting one of four devices, there is an OFFLINE position choice as well, which when selected stops any and all data throughput for the unit. A DB15 REMOTE port allows a user off-site monitoring and switch management from a remote location via contact closure switch commands.

LC Duplex Fiber Optic Switch Secure Off-Line position, Remote Control, Model 4291 Diagram

The QuickSwitch® 4291 Single Channel LC Duplex A/B/C/D/Off-Line Switch with Contact Closure Remote allows a device connected to the COM port access to the A, B, C, or D ports.  The QuickSwitch® 4291 is enclosed in a 1U, full rack size, all metal black chassis designed to fit in a standard 19" rack.

The switch may be controlled locally by manually operating the front panel pushbutton or remotely from the DB15 REMOTE port located on the rear of the unit.  The DB15 REMOTE port provides control through contact closure and allows the user to both control and monitor the switch position remotely.  The DB15 REMOTE port also allows the user the capability of locking out the front panel pushbutton controls.  The front panel LED display indicates the switch position and unit power status.

 FEATURES: 

  • Allows quick connection to any one of four devices from one COMMON device.
  • The switch ports are transparent to all data.
  • All fiber signals are switched via break-before-make MEMS-based mirror/prism switch technology and supports Gigabit data rates.
  • Switch reverts to the offline position on power loss and does not pass data.
  • Upon power up, unit remains in the offline position until commanded otherwise .
  • Front-panel pushbutton control.
  • Remote Contact Closure control and status provides dry contact logic to allow the control of the switch position and lockout state as well as obtain the present position and lockout status.
  • Front-panel LED's display present position and power status.
  • All fiber ports are LC Multimode, 50/125 micron, and support a wavelength of 1310nm.
  • 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 AB ports and vice versa.
  • Custom length rigorously tested and certified, LC fiber optic cables available for your switch management.

Wide Range Power Option Available: (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.  Has IEC 60320 C14 inlet. Ideal for international applications.
