Motivation
Implement a fully reconfigurable, flexible and bi-directional optical test-bed.
Experimental characterization of transmission impairments at very high bit rates (exceeding 10 Gbit/s).
Suitable to test optical nodes elements (dispersion compensator, OADMs, etc).
Test over SMF (G.652), NZDSF (G.655) or mix links.
Provide advanced formation to post graduation students
