An optical sub-assembly module comprises a fiber for delivering optical signals; a transmitter; a receiver; and an intermediate optical mechanism optically coupled to the fiber, the transmitter and the receiver. The intermediate optical mechanism includes a fiber-end interface for receiving the optical signals from the fiber or outputting the optical signals generated by the transmitter to the fiber; a transmission-end interface for receiving the optical signals from the transmitter; a reception-end interface or outputting the optical signals from the fiber to the receiver; and a filtering interface in the inside of the intermediate optical mechanism for realizing the optical signal delivery from the transmitter to the fiber and from the fiber to the receiver. The fiber-end interface, the transmission-end interface and the reception-end interface are parts of an integral whole while the filtering interface is a part of the same integral whole or an independent filter.
