Introduction
The latching Fiber Optic A/B/C/D Switch is a full-duplex, optical 4 port switch. It can be used to connect one
workstation to four different networks (one at a time) or to other remote devices. A front panel rotary style knob
allows the user to select which of four ports (A, B, C or D) is connected to the COMMON port on the switch. The
switch operates using a unique all-optical micro-mirror movement. When you turn the rotary knob on the front of
the switch to select a network, the internal micro-mirror movement redirects the optical beam from one network port
to another network port by rotating a miniature mirror. This technique eliminates the need to convert optical signals
to electronic signals to for switching and it is therefore transparent to data rates and protocols.
This switch is perfectly suited for applications where a selected connection must be maintained in the event of a
power failure. You should use a non-latching fiber optic switch like Model # SW1006A for applications requiring a
switch that falls back to pre-determined connection during the loss of AC power. These latching switches use power
only for switching the selected connection. No power is required to pass data through the switches.
Installation
Place the switch in a convenient stable location and connect the power supply unit to a reliable source of AC power
that meets the requirements shown in the Specifications section of this manual. Then change the front panel rotary
knob to switch between the different connection states to ensure that the latching fiber optic switch modules are in a
known position before connecting the switch to your fiber optic devices.
Connect the two fiber leads from the device to be shared to the switch port labeled COMMON. Connect the
networks or other devices to the user selectable output ports labeled A, B, C and D.
Your installation of this switch is now complete.
Operation
Operation is easy. Simply turn the knob on the switch front panel to route the signals. Turning the knob to “A” will
route signals between the COMMON Port and Port A. Selecting “B” routes the signals between the COMMON Port
and Port B, and so on….
The switch uses an internal mirror to switch between ports. The mirror directs a light beam from the COMMON
Port to Port A, or to Port B, C or D. There’s no optical-to-electrical conversion between the fiber optic connections.
Although power is required to change the selected connection, the latching optical switches continue to pass optical
data if power is lost or removed.
Troubleshooting
There are no user-repairable components in this switch. If service or technical support is required, please contact
technical support for assistance.
