<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">"<span>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)."</span></p>

<p class="x_MsoNormal">For the existing and new submarine fibre runs, do the amplifiers / repeaters require power?</p>
