Abstract

An optical transceiver with two circuit boards is disclosed. The optical transceiver includes two OSAs, two circuit boards, and a holder put between two circuit boards. The circuit boards are assembled with the holder made of resin by the snap-in, and this intermediate product is set within the housing of the transceiver. The cover of the transceiver is also assembled by the snap-in without using screws and so on.

Description

Technical field [0001] The present invention relates to optical transceivers, and in particular, the present invention relates to plug-in optical transceivers. Background technique [0002] Optical transceivers suitable for optical communication systems usually include: optical transmitting sub-assembly (hereinafter referred to as TOSA), optical receiving sub-assembly (hereinafter referred to as ROSA) and mounted on a circuit board to communicate with the above optical sub-assembly and host system Circuit. These components are encapsulated in the housing. The plug-in optical transceiver is inserted into a holder arranged in the host system, wherein the holder is equipped with an electrical connector, and the electrical connector receives the electrical plug installed on the circuit board of the optical transceiver; thus, the optical transceiver can Electrical communication with the host system. [0003] TOSA and ROSA are installed with respective optical devices. For example, TO...
