I am new to the world of layer-1optical failover solutions. I came across the NTT-AT Intelligent Optical Switch [1] 
while researching products that can be used to automatically switch a fiber path on link failure. Do any of you have 
experience with this particular product? Can anyone recommend a similar 1U product that can transfer an optical 
signal to a secondary path when there???s been a break?

Essentially, all you're looking for is a 1+1 optical splitter on transmit and photonic switch on receive.  
Many vendors make this, including from cheap sources[1] to optical protection cards from big vendors[2].

I'd also recommend Huhber+Suhner (Cube Optics) - these guys can customize optical line protection package, we use them 
ourselves.
