Optical module

An optical module, comprising an optical module housing, an optical fiber connector, a transmitter optical component, a receiver optical component and a printed circuit board, wherein

• the optical fiber connector, the transmitter optical component, the receiver optical component and the printed circuit board are arranged within the optical module housing,
• the optical fiber connector includes a transmitting interface optically coupled with the transmitter optical component, and a receiving interface optically coupled with the receiver optical component, and the transmitting interface and the receiving interface are arranged side by side to form a horizontal arrangement,
• the transmitter optical component and the receiver optical component are optically coupled to the optical fiber connector, and electrically connected to the printed circuit board,
• the printed circuit board is arranged along a horizontal direction within the optical module housing,
• the transmitter optical component including a transmitter optical component housing and a light-emitting device group arranged within the transmitter optical component housing,
• the receiving optical component including a receiver optical component housing and a light-receiving device group arranged within the receiver optical component housing, and
• the transmitter optical component housing of the transmitter optical component and the receiver optical component housing of the receiver optical component are stacked in a direction perpendicular to the horizontal direction along which the printed circuit board is arranged.
