Unlikely that distance has anything to do with it.

Retransmission alone works best as protection against shine. The retransmission channel only has 0.1Mbps bandwidth, after all. Rein is still best dealt with by fec+interleaving, but can be tuned better to leave a lower overhead too.

for 600m the downstream is fine.

your upload seems low tho.

My own line is about 600m to cab and I get 50Mb down and 14Mb up (does change sometimes if interleaving kicks in but that is about the norm).

In reply to a post by BatBoy:
Lol, no G.Inp is a retransmission technology that replaces FEC.


I wouldn't say it completely replaces FEC.
Rather it seems to mitigate/is less severe than old-style FEC on its own.


e.g. from my recently G.INP activated connection (some FEC/RSCorr is still going on (mainly on Bearer 0)):-

Re: Speed smashing estimates


[re: deleted] [link to this post] 		 
I'm about 650m from the cabinet, have DS attenuation of 20.9dB and sync downstream at 60.3mb with upstream at 10.5mb,

So, give or take a little, highly comparable.
