Overview
QuickSwitch® 6253 Quad Channel ST Duplex MMF Multi-Mode Fiber Optic A/B Switch with Voltage/Contact Closure Remote
QuickSwitch® 6253 Quad Channel ST Duplex A/B Switch with Voltage/Contact Closure Remote allows the user the capability of switching all four channels simultaneously between A and B positions by pressing the front panel pushbutton or remotely via contact closure voltage signaling using to allow both the control and monitor the switch position.
-
Field Proven, highly reliable, MEMS-based mirror/prism optical switching.
FEATURES:
-
Each channel allows access to two fiber optic networks from one fiber optic network device.
-
The switch ports are transparent to all data.
-
All fiber signals are switched via break-before-make MEMS-based mirror/prism technology.
-
Switch maintains position on power loss and continues to pass data.
-
Simultaneous control of all channels.
-
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, Multi-mode MMF, 62.5/125 micron, and support a wavelength of 850 nm.
-
The fiber ports are configured in a straight through scheme, where the TX is routed to the TX of the A/B ports, and the RX is routed to the RX of the A/B ports.
-
Custom length rigorously tested and certified ST duplex fiber optic cables available for your installation.
-
