To make it possible to easily introduce new F/W.SOLUTION: An OLT 120 includes: a first lower I/F board 140#1 in which update is performed with first F/W; a second lower I/F board 140#2 in which update is performed with second F/W that is newer than the first F/W; a receiving unit that receives a F/W combination module that includes a unique name of the first F/W but does not include a unique name of the second F/W in a common file header, which is a header of a common file area including the first F/W and the second F/W; a memory 132 that stores the F/W combination module; a file dividing unit 133 that divides the first F/W and the second F/W from the F/W combination module when an update instruction is received after the reception of the F/W combination module; and a file transfer unit 136 that transfers the first F/W to the first lower I/F board 140#1 and transfers the second F/W to the second lower I/F board 140#2.SELECTED DRAWING: Figure 2 【課題】新規なＦ／Ｗを、容易に導入できるようにすること。【解決手段】ＯＬＴ１２０は、第１のＦ／Ｗで更新を行う第１の下位Ｉ／Ｆ基板１４０＃１と、第１のＦ／Ｗよりも新しい第２のＦ／Ｗで更新を行う第２の下位Ｉ／Ｆ基板１４０＃２と、第１のＦ／Ｗ及び第２のＦ／Ｗを含む共通ファイル領域のヘッダである共通ファイルヘッダに、第１のＦ／Ｗの固有名称を含むが、第２のＦ／Ｗの固有名称を含まないＦ／Ｗ結合モジュールを受信する受信部と、Ｆ／Ｗ結合モジュールを記憶するメモリ１３２と、Ｆ／Ｗ結合モジュールの受信後に更新指示が受信された場合に、Ｆ／Ｗ結合モジュールから、第１のＦ／Ｗ及び第２のＦ／Ｗを分割するファイル分割部１３３と、第１のＦ／Ｗを第１の下位Ｉ／Ｆ基板１４０＃１に転送し、第２のＦ／Ｗを第２の下位Ｉ／Ｆ基板１４０＃２に転送するファイル転送部１３６とを備える。【選択図】図２
