A transmission/reception optical module has an optical transmission subassembly 182, an optical reception subassembly 183, and a circuit board 1 wherein the circuit board 1 is formed into one member by a rigid/flexible substrate. Circuit board main bodies 2a, 2b, and an optical reception subassembly fixation region 4 are formed by rigid regions 5A, 5b, and 5P. An area provided between the circuit board main body 2a and the optical reception subassembly 4 is composed of a flexible region 6P. A part of the circuit board main body 2 is composed of a flexible region 6.

A package with lock mechanism has: a package body to be slidably inserted into a cage and to be releasably locked by the cage; a slide member that is slidably attached to the package body, the slide member allowing the package body to be released from the locking by the cage when the slide member is slid to a predetermined position; and an operation lever that is rotatably attached to the package body. The operation lever allows the slide member to slide to the predetermined position while engaging to the slide member.

An optical communication module includes an optical package including at least one semiconductor optical device, an optical filter for reflecting light of a specific wavelength and transmitting light of an other wavelength, an optical block including a transparent material and the optical filter, a housing that houses the optical package and the optical block, an in-housing circuit board housed in the housing and mounting a peripheral electrical circuit for the optical package thereon, and an electrical connector electrically connected to the in-housing circuit board and exposed at a bottom surface of the housing. The optical block further includes a front lens portion at a front side face of the housing, a rear lens portion at a rear side face of the housing, a light inputting port, and a light outputting port. The optical filter is arranged to obliquely intersect with an optical axis passing through the front lens portion and the rear lens portion at a predetermined angle. The optical package is arranged such that an optical axis between the optical filter and the optical package is substantially orthogonal to an optical axis between the front lens portion and the optical filter.

A board assembly, an optical transceiver using same, and a method for mounting a board assembly that can relax a stress occurred at a flexible board. A board assembly 1 comprises a flexible board 2, a first rigid board 3, and a second rigid board 4. The first rigid board 3 and the second rigid board 4 are connected with each other by means of the flexible board 2. Since the flexible board 2 is preformed before the attachment, the stress occurred at the flexible board 2 can be relaxed.
