Title: Optical repeater
Inventor: NAKATSUGAWA MAKOTO
IPC: H04B10/2507
Filed: 1990-11-30
Abstract: PURPOSE:To prevent crosstalk by adopting an optical interrupter of an optical system for a changeover switch for setting loopback and its release. CONSTITUTION:In the case of setting a loopback, an optical interrupter 6-1 is closed and an optical interrupter 6-2 is opened so that a monitor control circuit 4 controls each of loopback control voltages 10-1-10-3 to allow an analog switch 8 to pass through an opposite line data signal 2. Since the setting/release of the loopback is implemented by using the optical interrupter of the optical system in this way, a crosstalk caused by interference between its own line data signal 1 and the opposite line data signal 2 being a problem of the analog switch 8 of the electric system is not caused.
