Chapter 2: Introduction
Introduction
The non-latching Single Mode Fiber Optic A/B Switch is a
full-duplex, optical 2 port switch. It can be used to connect
one workstation to two different networks (one at a time)
or to other remote devices. A front panel rotary style knob
allows the user to select which of two ports (A or B) is
connected to the C 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 the other
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 use as a fall-back switch
when a pre-determined connection is desired in the event
of a power failure. You should use a latching fiber optic
switch like Model SW1035A for applications requiring a
switch that maintains the selected connection during the
loss of AC power. Latching switches use power only for
switching to the selected connection. No power is required
to pass data through the switches.

Chapter 3: Installation
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.
This switch is ideal for use in fall-back applications
where a pre-determined connection is desirable in the
event of a power failure. Connect the two fiber leads
from the device to be shared to the switch port labeled C.
Connect the A port to the network or device to which you
want to be connected if power is lost. Connect the
remaining network or device to port B of the switch.
Your installation of this switch is now complete.
Chapter 4: Troubleshooting
Troubleshooting
If the Fiber Optic A/B Switch fails to operate, check the
following before calling for technical support.
1. Ensure that the power supply connected to a power
source and to the switch.
2. Check the fiber optic connectors for proper
connections to the correct ports of the switch.
3. Operate the switch knob to verify that it’s tightly
secured to the switch shaft and does not spin loosely.
4. Verify the integrity of the fiber optic leads by
replacing a suspect lead with a spare.
