That is, the sub-relay board case of the sub-relay board is provided with an intrusion prevention member so as to fill a gap formed between the sub-relay board case and the optical fiber cable with the sub-relay board case closed. Yes.

  Even if a third party tries to insert a special wire for illegal use up to the position of the sub relay board installed inside the sub relay board case in order to make a fraud through the opening, the gap is left. The intrusion prevention member that is blocked can reliably prevent the special wire from entering.

  In addition, as a configuration between the intrusion prevention member and the sub-relay board case, a seal seal that regulates the mounting position of each other is provided. And by confirming the sticking state of the seal sticker, it is confirmed that the installation position of the intrusion prevention member attached to the gap between the opening and the optical fiber cable has shifted or the intrusion prevention member has been removed from the opening. can do. And it becomes possible to prevent that an illegal act is repeated.
