Low-Crosstalk 3 × 3 Optical Cross-Connect Using Fiber Bragg Gratings.

A power-compensated, 3 × 3 reconfigurable, multi-wavelength, and bidirectional optical cross-connect for all-optical networks is proposed using strain-tunable fiber Bragg gratings and optical circulators. This article presents the experimental study for the induced crosstalk due to the optical cross-connect. The reconfigurable, multi-wavelength, and bidirectional cross-connect operation and performance are experimentally demonstrated, and crosstalk is determined to confirm the low penalty incurred. The demonstration shows that the selective reconfigurable, multi-wavelength, and bidirectional optical cross-connect offers high reconfigurable capability, flexibility, and survivability in an optical communication network.
