Subsea Cable Beach Landing Infrastructure

Here's a very informative diagram of subsea cable landing infrastructure. Thanks to Nilesh N. The segment from the beach manhole to the cable landing station is called the front haul. From the beach manhole to the cable buried offshore is called the shore end. The ideal way to land a cable is to install a big pipe called a bore using directional horizontal drilling. The subsea cable goes through the bore pipe to a beach manhole where it is spliced to standard terrestrial fibre, usually G.652d or G.657a. Note it is possible to create a fibre ring between the manhole and the CLS for greater resiliency. All it requires is a cable splitter. Note that diagram places the back up generators in the basement. Not a good idea in a tsunami or hurricane zone subject to flooding. The Japanese nuclear accident happened because a tsunami flooded the reactor's basement where all the backup generators were located. No back up power for cooling led to the meltdown. So the earthquake destroyed...
