Gisma Series 40

The pressure watertight fibre optic and hybrid connectors of series 40 have been developed for long-term underwater applications due to robust design. Under difficult environmental conditions and high ambient pressures, the waterproof plugs offer high operational reliability


With the double o-ring, seal in the mating area, the long-term performance is ensured for different applications. In addition, the metric locking thread in the locking sleeve allows secure locking.

High-quality PC optical fibre inserts ensure secure data transmission. The modular contact inlay can be fitted on any contact space with electrical contacts
to provide different hybrid contact arrangements
With a large range of dismountable endbells, diverse underwater cables are adaptable
