It comes down to them not listening to me in the beginning about doing
BiDi when a consultant filled their heads with "everyone needs 1Gbps FDX
all the time." Apparently they didn't understand that BiDi WDM *is*
1Gbps FDX. Now about 40 customers in, they see the light (pun intended).
Nobody is using more than 80-90Mbps sustained. I'm very sure we can do
16 split 2.5G PONs without issue.

Hi,
I am assuming below that you want to start with Active Ethernet, then migrate
to GPON. If that is not your use case, ignore the rest of this reply.
844GE can do both Active Ethernet and GPON. The drawbacks are:
- you are not able to install more than 2x 844GE per AE CSFP, as AE is a point
to point technology. So be aware when you do the planning, as you cannot really
mix AE and GPON. And each 844GE in AE mode will use one fiber.
- AE and GPON use different SFPs and different ports on the card, so you will
need different cards in your 2 scenarios, to achieve some density: AE - GE-24,
GPON - GPON-8. Plus different optics (CSFP vs GPON).
You might end with a more expensive deployment doing AE then converting to GPON
than just doing GPON from the start, if that’s where you want to get in the end.

Anybody deploying these? I finally got the folks writing the checks on the GPON
bandwagon. Looks like they want to go all-out with a full Calix infrastructure.
So we're going to install the 844GE's at the existing customers and temporarily
convert to BiDi, then GPON later as it grows. So I need to get some BiDi SFPs.
I want Tx 1490 / Rx 1310 at the head-end.. right? That's what it looks like to
me, just want to make sure I'm not being stupid.
