Fiber Bragg grating-based rearrangeable nonblocking optical cross connects using multiport optical circulators

Fiber Bragg grating (FBG) based rearrangeable nonblocking optical cross connects (OXC's) using multiport optical circulators are proposed in this letter. The use of multiport optical circulators instead of three-port circulators can be more efficient for large optical cross connects systems. Performance evaluations of proposed large dimension optical cross connects are investigated.
