Description
図1は、第1の実施形態に係る光モジュールの斜視図である。光モジュール100は、送信機能及び受信機能を有するトランシーバであり、QSFP-DD(Quad small form- factor pluggable Double Density)規格に適応しており、伝送レートは400Gbit/sであるが、他の規格や伝送レートでの使用を限定するものではない。光モジュール100は、モジュールケース102(筺体)と、光サブアセンブリ10と、第1基板12と、第2基板14を含む。
図7は、第2の実施形態に係る第1基板及び第2基板の接続構造の断面図である。本実施形態では、第1絶縁壁224及び第2絶縁壁236が相互に接触しないが、それでも二重の壁が形成されるので、ハンダ240の溶融時の流動による短絡防止の効果が得られる。
図8は、第3の実施形態に係る第1基板及び第2基板の接続構造の断面図である。本実施形態では、第1絶縁壁324は、第2基板314の第2面328に接触しない。第2絶縁壁336は、第1基板312の第1面318に接触しない。第1絶縁壁324及び第2絶縁壁336は、相互に接触しない。
