There's some more information regarding the scalability of the
ADVA-based OSA product in the associated BT SIN note:

Simon,
I've been looking at this recently as well, so I can share what I've
learned. The only difference between the various FSP3000 units is the
number of wavelengths.
The 1U box has two slots (I assume the second one is reserved for the RO2
resiliency option). If you go for the 'single' option, that is all you get,
whereas if you go for the 'standard' option you also get a filter tray that
gives you capacity for up to 4 wavelengths (although you still need to pay
BTO to open them up). The 7U is the big boy that has capacity of up to 32
wavelengths.
The RO2 option is a resiliency option. This means they will bring two
separate sets of fibre into the building at different ingress points and
make best efforts to route them diversely. There's a much higher cost for
this because they're technically provisioning two separate sets of circuits,
and often to get the diverse path into your building will involve excess
construction costs. The benefit is however that you do get to use both sets
of circuits completely independently.
More info on RO2 is here:

The problem with OSA is it's huge overkill for basic 10gig applications
(such as customer access tails). We're all waiting with bated breath on
Openreach replacing the old expensive 10Gig WES product with a newer 10Gig
EAD, which I'm hoping will be as aggressively priced as the rest of their
Ethernet portfolio.
Hope that helps.
Thanks,
Charlie.

All,
Whilst I await (somewhat slow) response from our Openreach account manager,
can
I seek the advice of the collective...
When I try to get a quote for an OSA (FSP3000) on Openreach's portal, I'm
presented with several options...
Bearer Option:
- STD 1U Single
- STD 1U Standard
- STD 7U Standard
- RO1 7U
- RO2 1U Single
- RO2 1U Standard
- RO2 7U Standard
10GBit/s Wavelength:
- 10:1 Muxponder
- Enterprise 5 port
- Long Reach Single Port
All I want is a point-to-point 10GE link. Which options should I be
choosing? :)
I *think* I want STD 1U Single and Enterprise 5 Port, but would
appreciate
some confirmation from someone who's done this before...
If I want to be able to add extra wavelengths in the future, should I choose
a different option up front?
I've tried reading the documentation on the Openreach website, and it's all
very detailed, but pretty much assumes you know what you're doing already.
Many thanks,
Simon
