摘要
The present invention relates to passive optical networks and more particularly to protecting a passive optical network;A three way coupler for a Passive Optical Network (PON). Terminals Ta, Tb, Tc input optical signals a, b, c, respectively. At least one splitter splits for splitting optical signal a into signals a1 and a2, optical signal b into b1 and b2 and optical signal c into c1 and c2. At least one adder adds signals a1+c2, a2+b1 and b2+c1.
