摘要：A first reconfigurable optical add/drop multiplexers (ROADM) and a secondROADM are connected by a primary light path and a protection light path. The first
ROADM includes a first direction and a second direction, and the second ROADM includesa third direction and a fourth direction. The primary light path is coupled between thefirst direction and the third direction, and the protection light path is coupled betweenthe second direction and the fourth direction. Transmissions on the primary light path aremonitored, and when a problem is detected on the primary light path, the first and thirddirections are deactivated and the second and fourth directions are activated so thatadditional light signals are sent on the protection light path and not on the primary lightpath.
