Description
図1及び図2は、光モジュール10を示す斜視図であり、それぞれ反対の方向から見た図である。図1及び図2に示されるように、光モジュール10は略直方体形状をしており、一方側の端部に光コネクタを挿入する挿入口11を有している。本実施形態に係る光モジュール10は、光送信用のコネクタと光受信用のコネクタとを挿入する2つの挿入口11を有する光トランシーバであるが、光送信モジュールや光受信モジュールに本発明を適用できることは言うまでもない。また、光コネクタを挿入する挿入口11の数も2つに限定されない。光モジュール10は、発光素子、受光素子、及び各光素子を駆動するための駆動回路が形成された回路基板14が内蔵され、金属製のハウジング12によって覆われている。この光モジュール10は、ハウジング12が金属製であるため、ノイズに対する耐性や放熱性が高いという利点がある。また、図2に示されるように、挿入口11を有する端部と反対の端部(以下、「挿入方向端部」という)において、回路基板14の一部が露出されている。本実施形態に係る光モジュール10は、図2に示されるように、挿入方向端部において、回路基板14が露出された側と反対に位置する縁部15が凹設されている。
