Yeah, I have no idea why you can't see our posts. I think you're the only one.
I have checked the block settings too.

Title: Re: [AFMUG] Future FTTH bandwidth usage standard
Chris,
Does it really matter? If you are AE you get 1GB per customer dedicated. Not too hard or expensive to to bump that to 10GB per customer dedicated. GPON does 2.5Gbps per pon usually shared by 32 customers. New 10 Gbps PON will do
How do you forecast that to increase in the future? Double every year?
Every 2 years? Is there a Moore's Law for bandwidth usage?

Is there any standard or common rule of thumb to design for future usage when
designing a FTTH
I'm looking for a small enclosure that has either AC or TEC cooling to
house a PON OLT and power equipment. Would be nice if someone made an
outdoor rated PON OLT that is affordable, but those don't seem to exist. I
would be attaching this enclosure to a utility pole.

Philosophical question. With infrequent outages I would prefer to keep people

ceases to function.
If you have protracted outages get a generator. I don’t see a use for lvd
equipment unless it is in a remote area
I think around 10.5 volts is a typical setting on non adjustable or factory
preset units. 21 volts for a 24 volt system.
LVDs typically have some hysteresis, so batteries have to come back up to
something like 12 volts for the loads to get reconnected.
