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
