Subject: Cheap switch with a couple 100G
I keep hearing how cheap 100G is compared to 40G and it doesn't seem to hold
true
The MX204 can split each 100G port into 4x10G. Why not 4x25G ? This would
give you 16x 25G which seems quite reasonable.

I very specifically said "Juniper MX". ;)

At this point, with 400g coherent in production never mind long-haul testing;
why bother lighting with anything slower than 100g coherent, especially at
essentially the same price. It just makes no sense. It got skipped. We’re
better for it IMO.

The mux isn't the problem, it's that there aren't SFP28 optics commonly
available in C/DWDM wavelengths. Yet. If they were, well maybe...

If it is passive, you could tell them it is for 10G but use it for 25G?

I'm really not sure that your statement makes sense by itself.

That's because, in active transport at least, 100G makes far more sense.

You may start seeing passive 25G WDM soon. Finisar have a DWDM tunable,
I believe.

The argument should be 50G is cheaper than 40G.
Because serdes is 25G typically, you get 25, 50, 100 without gearboxes
and retimers, so less pincount, less thermal, higher density, lower
cost.

I keep hearing how cheap 100G is compared to 40G and it doesn't seem to hold

Cisco Nexus and Arista both have switches with 48x 10G ports and 2x - 6x 40G
ports for under $1k. Swap those 40G for 100G and you're at $5k - $7k.
