ABSTRACT:
In a digital optical submersible repeater the electronic and opto-electronic components are housed in an hermetically sealed modular assembly (20, 60, 70) of a first regenerator module (20) for one fibre (7, 6a), a second regenerator module (60) for the second fibre (6, 7a) of the pair of fibres, and a power module (70) for extracting power from the power feed conductor of the cable. In each regenerator module (20) the transmit laser (8) and the receive PINFET diode are on diametrically opposed faces, and power feed and optical signal feed are disposed in spaces between the modules and the inside surface of the repeater housing (1). The modular assembly is resiliently secured to the bulkhead (2).
