[AusNOG] submarine fibre amplifier question

[Christopher Hawker]

Hi Bryan,


"Repeaters are powered by a constant direct current passed down a conductor near the center of the cable. All repeaters in a cable are powered in series. Power feed equipment (PFE) is installed at the terminal stations on the land. These PFEs inject huge voltage into the line - 3,000, 4,000, and up to 10,000 volts - to power each repeater on the cable (now you can understand why Jaws went to shark heaven after his mid-morning snack)."

Hope that helps.


Thanks,

CH.

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.
