Thank you

I know SLTE can be further than 100m

If the SLTE and PFE are not going to be co-located next to each other, the
2 main considerations are:

   - The Management signal between the SLTE and the PFE, which is
   generally ran over copper. So 100m becomes the distance limit. However, you
   can mitigate this by doing media conversion between optical and copper.
   Also, it's quite possible that modern PFE's and SLTE's can run Management
   traffic over optical signals. One would have to check with the vendors.


   - The SLTE Launch Tx power into the wet plant toward the 1st repeater.
   You'd have to design this for every specific case; whether you want to
   co-locate the SLTE and PFE, or if you want to separate them. This is
   critical so that all payload channels are correctly balanced.

is there any limitation of where an SLTE can be placed in terms of
distance from PFE?

I have looked in to usual palaces and i was unable to confirm there is any
requirements for any distance. Any cons can you guys think of that you want
to share would be appreciated.

here are places I have looked at

Nowadays however, the CLS is looked at more like an ILA shelter, or
when feasible cable landings are going directly into metro CNDCs as
the physical gear is getting smaller and smaller and more suitable for
colocation.

Nowadays, the SLTE sits in a proper data centre.



There’s still the small matter of 11,000volts of power or more…
 That’s usually kept out towards the sea.

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