QuickSwitch® Model 6276 Single Channel ST Duplex A/B Fiber Optic Switch with DB9 for Voltage Remote Control Operation
Overview
The QuickSwitch® 6276 Single Channel ST Duplex A/B Switch with Voltage Control Remote allows a device connected to the “COM” port access to the “A” or “B” port. The switch may be controlled locally by manually operating the front panel pushbutton or remotely via the DB9 Voltage Control Remote port located on the rear of the unit. The DB9 REMOTE port provides control by voltage level logic and allows the user to monitor the switch remotely by a set of dry contacts. The front panel LED display indicates the switch position and unit power status.
FEATURES OF THE MODEL 6276 ST DUPLEX VOLTAGE REMOTE SWITCH:
- Access any one of two separate fiber optic networks from one computer.
- The switch ports are transparent to all data.
- 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.
- Front-panel pushbutton control.
- Remote Voltage control provides voltage level logic to allow the control of the position as well as a set of dry contacts for obtaining the present position.
- Front panel LED's display present position and power status.
- All A, B, and COM ports are ST duplex, Multi-mode, 62.5/125 micron and support a wavelength of 850 nm.
- 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.
- Optical data throughput scalability.
- Custom length rigorously tested and certified, ST cables available for your switch installation.
The QuickSwitch 6276 is enclosed in a 1U, full rack size, all metal, black chassis designed to fit in a standard 19” rack.
