Abstract
【解決手段】APD(Avalanche Photodiode)のカソードと電源端子Tv1の間に自己バイアス抵抗R1が接続されている。サージ対策用のツェナーダイオードD1のカソードが電源端子Tv1と自己バイアス抵抗R1の接続点に接続され、アノードが接地端子TGNDに直接的に接続されている。接地端子TGNDは電気的に接地される。ツェナーダイオードD1の降伏電圧Vzは電源端子Tv1に印加される電源電圧Vapdより大きい。
【選択図】図1
Description
図1は、本発明の実施の形態1に係る光モジュールを示す図である。アバランシェフォトダイオードAPD(Avalanche Photodiode)のカソードと電源端子Tv1の間に自己バイアス抵抗R1が接続されている。従って、APDと自己バイアス抵抗R1が直列に接続され、電源端子Tv1から自己バイアス抵抗R1を介してAPDに電圧が供給される。
図2は、本発明の実施の形態2に係る光モジュールを示す図である。本実施の形態ではノイズ除去用のコンデンサC1は、一端が電源端子Tv1と自己バイアス抵抗R1の接続点に接続され、他端が接地端子TGNDに接続され、ツェナーダイオードD1に並列に接続されている。その他の構成は実施の形態1と同様であり、実施の形態1と同様の効果を得ることができる。
図3は、本発明の実施の形態3に係る光モジュールを示す図である。本実施の形態ではツェナーダイオードD1の代わりに、互いに直列に接続された複数のツェナーダイオードD_1〜D_n(nは2以上の任意の整数)を用いている。その他の構成は実施の形態1と同様である。複数のツェナーダイオードD_1〜D_nの降伏電圧を合計した値Vz_1+Vz_2…+Vz_nは電源電圧Vapdより大きいが、電源電圧Vapdに可能な限り近づけることで安定的なサージ耐性を得る。
図4は、本発明の実施の形態4に係る光モジュールを示す図である。本実施の形態ではツェナーダイオードD1の代わりに、互いに直列に接続された複数のツェナーダイオードD_1〜D_n(nは2以上の任意の整数)を用いている。その他の構成は実施の形態2と同様である。複数のツェナーダイオードD_1〜D_nの降伏電圧を合計した値Vz_1+Vz_2…+Vz_nは電源電圧Vapdより大きいが、電源電圧Vapdに可能な限り近づけることで安定的なサージ耐性を得る。
