<P>PROBLEM TO BE SOLVED: To provide an electromagnetic environment adaptability structure of an optical transceiver having high general versatility and high EMC characteristics. <P>SOLUTION: An electromagnetic wave absorption material is applied to a surface of a housing of an optical transmitter/receiver module comprising an optical receiver module 1a and an optical transmitter module 2a, on the whole surface excluding an opening of a receptacle. A coating film of the electromagnetic wave absorption material can be easily formed even on a receiver module fixing part 11 and a transmitter module fixing part 12 that have a complicated shape. Even when the optical receiver module 1a and the optical transmitter module 2a are configured to be mounted on the fixing parts 11 and 12 while retaining a degree of freedom of swinging, the electromagnetic wave absorption material can be disposed without any gaps on the possible whole surface of the housing without influencing the function of a mechanism for retaining the degree of freedom of swinging so as to easily acquire the high EMC characteristics. <P>COPYRIGHT: (C)2013,JPO&INPIT |
