SSFP vs nothing
« on: March 23, 2016, 03:39:30 PM »

At the moment I have no SSFPs at all, the modems just go into a straight-through faceplate that goes into the test socket and covers the front. I have no phones at all anyway.

My questions (*):

1) Would there be any advantage to having a high quality SSFP (one of the BT 'Pressac' ones) in terms of lightning protection ?

2) Any noticeable disadvantage in speed ?

3) Which BT generation for my ultra-long (>7300 m) line ?

Thoughts.

(*) sincere apologies if this has been covered before (drugs).

I'm sure we've discussed this in the past, so I'll just quickly give you my opinion . . .
  • No, none at all.
  • The fitting of any type of filter into the circuit will be responsible for a degree of insertion loss. Insertion loss => degraded synchronisation speed and, thus, throughput speed.
  • The latest, which is the Mk 3, if you are intent on experimenting.

I read somewhere that BT are removing the lightning suppression on master sockets due to their impact on broadband

You are absolutely correct. That somewhere was here, a few years back!  ;)

Apologies, Burakkucat, I did a search which 'failed', as I drowned, but I've now had more success:

There's no need to apologise. I knew we had discussed the topic previously but couldn't put my paws on its URL . . . which you have subsequently discovered and shown, above.  :)
