I've been doing some research into G.FAST and come up with some interesting conclusions. Yes they are a bit off the wall!
G.FAST isn't FTTDP necessarily.
If you're near enough to an existing cabinet you'll likely be able to order G.FAST. Why?
1) Deployment can be done on demand based on orders for 330 G.FAST products - within distance limitations. Cut down demand. But gives a nice return.
2) No civil engineering is required. Civils are bad..
3) Work can be undertaken by third party engineer. Why not an Openreach engineer? They are committed to BDUK for a very very long time.
4) There is room in the existing cab for a G.FAST module. The cab has power it is also compatible with the FTTP2 2.5Gbps/10Gbps G-PON due to the fact it has a C-WDM splitter pre-installed unless it was one of the original 2010 cabs then you are SOL.
So. From research I've done it looks like this is possible.
At 500 you can get 50 Mbps FTTC and 100Mbps G.Fast.
At 400 you can get 63 MBps FTTC and 200Mbps G.Fast.
At 300 you can get 76 Mbps FTTC and 280Mbps G.Fast.
At 200 you can get 80 Mbps FTTC and 300Mbps G.Fast.
In my area 100,000 properties 30-40% would get >200 Mbps. Maybe ish.
Note: The FTTC figures are not exact but based on real data. The G.FAST is a rough guess but also based on real data. I think BT are getting better results due to the quality of the equipment being far better than they had anticipated.
Also BT have said FTTP2 is ready to go and that is a precursor to G.FAST as G.FAST uses 10Gbps FTTP2 backhaul - all that is required is a new line card.
So will FTTP2 follow a similar principle and be available on demand. Will G.FAST FTTDP fit into that same on demand model?
So is this how it might go?
FTTC <600 meters (rolled out 2016/17)
- G.FAST on demand 300Mbps with zero build cost.
- FTTP2 on demand 1Gbps/10Gbps with low build cost. NO 330 OD
FTTC >600 meters (>2018)
- FTTDP on demand 330Mbps with build cost
- FTTP2 on demand 1/10Gbps with build cost
FTTP Area (2015???)
- FTTP2 on demand 1Gbps
Actually why bother with FTTP2 OD.... Hmmm.
?? Any ideas?
BT Infinity FTTP 80Mbps/20Mbps
