Tyco Electronics Low Profile
Fiber Optic Switches are
miniature, board mountable
devices that permit the
switching of an optical signal
from one fiber to another.
Switching is accomplished
by a slight pivoting motion
of a spherical mirror which
reflects the optical signal
to the appropriate fiber. This
patented imaging
technology provides very
low optical loss.
Tyco Electronics’ Fiber Optic
Switches can be terminated
with any Tyco fiber optic
connector, and they are
available in the following
configurations:
■1 x 2 SPDT Switch
■Dual 1 x 2 DPDT Switch
Tyco Electronics’ SPDT and
DPDT Switches permit the
transfer of optic signals from
an input fiber to either of
two output fibers. Switches
are applied to the positive
terminal. The switch reverts
to its original state when
power is removed.
■2 x 2 Bypass Switch
Tyco Electronics’ Bypass
Switches provide bypass
protection for fiber optic
ring networks. They also
provide bypass protection
for fiber optic ring networks
per IEEE 802.5 and ANSI
FDDI standards.
A self-test path permits
testing the node's transmit-
ter against its receiver when
the switch is in the bypass
mode. This transmitter -
receiver path is attenuated
to prevent saturation of the
receiver, while maintaining
minimal light loss in the
bypass path.
