FIG. 1 is a perspective view of the optical transceiver according to the first embodiment. The optical transceiver group 1 is an aggregate in which a plurality (four in this example, for example) of optical transceivers 10 are connected in parallel in the width direction so that the tips 100a are aligned. The optical transceiver 10 is a Bail type optical transceiver, and is a module that converts a received optical signal into an electrical signal and transmits the electrical signal, or transmits the received electrical signal as an optical signal. The optical transceiver 10 has a main body 100 and a bail 102. The main body 100 has an insertion port 101 at its distal end 100a. An optical fiber connector is inserted into and removed from the insertion port 101. A bail 102 is provided on the opening periphery of each insertion port 101. The bail 102 can be rotated by a shaft 102a. The bail 102 is connected to the second latch mechanism 103.

An upper step 100b and a lower step 100c are formed at the tip 100a of the main body 100. The upper step portion 100b and the lower step portion 100c are one of the physical outlines defined by MSA (Multi-Source Agreement). In MSA, physical dimensions are defined for each form factor such as QSFP (Quad Small Form-Factor Pluggable) or SFP (Small Form-Factor Pluggable). In addition, a gap 100d is formed between the tip 100a of the main body 100 and the bail 102.

The latch mechanism 103 is provided on both side surfaces 100e of the main body 100. The latch mechanism 103 fixes or releases the optical transceiver 10 with respect to a cage 900 (see FIG. 9) described later in conjunction with the rotation of the bail 102. The latch mechanism 103 has a sliding member 103 a and slides in the longitudinal direction of the optical transceiver 10. One end of the sliding member 103 a is connected to the bail 102. The other end of the sliding member 103a has a protrusion 103b. The sliding member 103a is in contact with a slope surface (not shown) on the back surface of the sliding member 103a. The slope surface is inclined outward from the inside of the side surface 100e from the rear end 100f of the main body 100 to the front end 100a. The protrusion 103b advances or retreats with respect to the side surface 100e by sliding of the sliding member 103a.

The rear end 100f of the main body 100 is inserted into the cage 900. The cage 900 is connected to a printed circuit board. A circuit is mounted on the circuit board 90 (see FIG. 9).
