Important Notices
CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All –5, -7, -8, and -9 Models use laser diodes. These solid-state
laser diodes are located in the optical ports of these units. Laser
diodes produce invisible radiation that may be harmful to human
eyes. Never look directly into the optical port of any fiber optic
unit designed to operate with single-mode optical fiber.
NOT FOR LIFE SUPPORT SYSTEMS
Liteway, Inc. does not authorize or warrant any of its products or
accessories for use in critical life support systems or applications
of any kind.

OPERATING INSTRUCTIONS
Optical Protection Switch
OS-7321-x
The OS-7321 is an optical path protection switch, providing a self
healing network. This optic switch detects loss of optical power in the
primary optical path and automatically switches to the secondary
(backup) path. When the primary link is restored, the network path is
restored to the primary path. The optical protection switch can be
controlled via three methods; front panel manual switch, remote
control signal, or the automatic internal monitoring circuitry. The
switch also contains a transmitter splitter for creating the redundant
transmit path. Technical Specifications
Switching Time < 10 ms
Back Reflection < -50 dB
Insertion Loss < 1.5 dB
Cross-talk < -50 dB
Mechanical Life > 1 Million cycles
Switch sensitivity Adjustable -43 dBm to -29 dBm
Sensitivity Data rate DC to 3 Gb/s
Electrical Connector 6 pin removable terminal block
Temperature Range -20º to +70ºC
Operating Power Requirements 11-24 VAC/DC @150 mA, 110/220VAC
or -48 VDC (+/-2)
