PURPOSE:To improve the reliability by insulating an electric circuit part and a power feeding means of the optical amplifying repeater from a pressure resistant housing. CONSTITUTION:The constituting part of the optical amplifying repeater is divided into an optical circuit part 5, an electric circuit part 6 and a power feeding means 8, and only the part 6 and the means 8 are insulated from a pressure resistant housing 9. Accordingly, a heat radiation characteristic related to the optical circuit part 5 being sensitive especially to a temperature variation becomes satisfactory easily, and also, the part for securing a pressure restance characteristic is decreased, and the assembly of a device is facilitated. Also, by preventing the fault of optical being sensitive to a temperature variation, the reliability can be improved. |
