For Fail-Safe Fiber Optic Bypass Applications  

 Block diagram of optical swtich    

The LuxLink OS-3122 is a 'fiber optic relay' that can be electrically controlled. The optical path through the units is purely optical; i.e. there is no optical to electrical to optical conversion. There is no electrical loss or electrical bandwidth limit on the fiber optic path. The optical path can be select via a front panel switch or via contact closure input. In event of loss of power, the unit has a failsafe mode that returns the switch in to bypass mode.  Common applications for this device are optical routing, system bypass, ring network restoration, and loop-back testing.

For applications where two independent optical channels need to be switched, such as dual SONET rings, the OS-3222 is two OS-3122 in a single package. For Telco operations, -48 VDC versions are available. These versions are the OS-1202, OS-2202, respectively and only operate from -48VDC.
