Title (EN) THREE WAY COUPLER FOR A PASSIVE OPTICAL NETWORK
(FR) COUPLEUR TROIS VOIES POUR RESEAU OPTIQUE PASSIF
Abstract: front page image
(EN)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.
(FR)L'invention porte sur un coupleur trois voies pour réseau optique passif dans lequel les bornes Ta, Tb, et Tc reçoivent respectivement les signaux optiques a, b et c. Un dédoubleur au moins partage le signal optique a en signaux a1 et a2, le signal b en signaux b1 et b2, et le signal optique c en signaux c1 et c2. Un sommateur au moins additionne les signaux a1+c2, a2+b1 and b2+c1.
