Abstract
An optical repeater for an undersea telecommunications system has a tubular casing (1) closed by a bulkhead (2) with a tail cable gland (2a) providing a common feed through for electrical power conductor (39) to power the regenerator and for optical fibres (28) for optical intelligence signals. Then the electrical power conductor and optical conductor are fed through separate glands ((40) and (32)) which facilitates manufacture and individual pressure testing prior to assembly in the regenerator.
