Even if the PFE and SLTE are side-by-side inside a room at the
CLS, the physical connection between them typically happens inside
the BMH (beach manhole).<br>
<br>
So provided you can run the Management traffic between the SLTE
and PFE optically, you can separate both devices as far as your
optics can carry the full channel payload toward the wet plant.
That could be anywhere between 80km - 120km, depending on your
optics and Tx launch power requirements.<br>

Nowadays, the SLTE sits in a proper data centre.<br>

Yes, PFE's will generally live at the CLS.<br>
