Re: [AusNOG] submarine fibre amplifier question

Adding to the earlier responses - yes, the cable generally has a copper tube as a power conductor, which also act as a little bit of protection for the fibres which run in the centre of the tube/cable. Pump one shore-end to +3000 - 5000V, the other shore-end to -3000 - 5000V (depends on number

Re: [AusNOG] submarine fibre amplifier question

Generally speaking, yes. Most submarine cables I’ve seen have a conductor running through them as well, fed DC current from either end. Chris > On 6 Feb 2018, at 8:43 pm, > wrote: > > I should know the answer to this but my

[AusNOG] submarine fibre amplifier question

I should know the answer to this but my brain is frazzled and my research is sending me around in circles. For the existing and new submarine fibre runs, do the amplifiers / repeaters require power? My favourite number today is 37. Kind regards, Bryan O'Reilly Founder - Telco
