[ The first housing 110 of the optical adapter 100 may be provided with a second aligning portion 210 instead of the first aligning portion 210 for coupling the optical transceiver module 3 and the optical adapter 100, 230 are provided. That is, the second alignment unit 230 is provided in the first housing 110 instead of the first alignment unit 210, so that the alignment pins 233 are inserted into the fixing grooves 32a and 32b of the optical transceiver module 3, The optical adapter 100 and the optical cable module 5 are connected to each other. According to the present embodiment, even when both the optical transceiver module 3 and the optical cable module 5 are formed of a gender of the arm, they can be connected to each other by using the optical adapter 100.

When the optical adapter 100 is used, even if the optical transceiver module 3 and the optical cable module 5 do not match the arm / gender gender, the optical communication network can be constructed by being connected to each other.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. And changes may be made without departing from the spirit and scope of the invention.
