Abstract
A bidirectional optical module includes a TOSA, a ROSA and an optical filter. The TOSA includes a light emitting unit and a thin film LiNbOx modulator, and the thin film LiNbOx modulator is optically coupled with the light emitting unit. The ROSA is connected with the TOSA. The optical filter is provided for a fiber port which the TOSA shares with the ROSA.
