We present extensive hydrogen data on our installed submarine and underwater cables with no hydrogen barrier through nearly 10 years. The hydrogen induced losses have stabilised at low levels corresponding to loss increases of 0.010.04 dB/km at1550 nm, dependent on cable type. Accelerated tests have shown that the hydrogen in the installed cables originates from the cable production, and will decrease in a time scale of 10-20 years. Measurements on cables with hydrogen absorbing materials andhermetic fibres have shown no traces of hydrogen in the fibres.
