Looks like you’re right. Too many 7xxx model numbers. Either way, same result.
The MAC layer in the switch treats it like a QSFP port would be.

I'm pretty sure that this is only available on 7150S which is FM6000, not
broadcom at all.

You don’t use 40G modules at all. Just 4 x 10G SFP+.
The Broadcom trident chip is configured at the MAC layer for 40G, so it’s
identical to a real 40G port inside.

The only problem is that with BASH based solutions is
I suspect that implies that you can just take a 40Gbase-SR4 module and
break it out into individual "10G" multi-mode pairs for DWDM use. Has
anyone tried this? I'm also very interested in using that strategy.

Indeed. Arista does (did?) make at least one platform where you can do this.

Subject:
Many switches based on BCM Trident ASIC allow you to configure 4 consecutive
SFP+ ports as 40G link (not LACP, but using real hardware 40G framing).
In such case, you can plug 4 DWDM SFP+ modules directly into the switch, without
the need for any reformer.

Whether a 40G port can be broken into 4x10G is dependent on the
router/switch hardware and the optic you use. Good news is that most 40G
ports are capable of being broken out into 4x10G, since a 40G port is
usually operating as 4x10G internally anyway to the ASIC. The QSFP you'll
need would be a
hey,
I want to take advantage of the fact that 40G is transported as four
individual streams. Each of the four streams are to be converted from 850
nm to a 1550 DWDM channel (one channel per stream). And the reverse at the
other end of the link.
You probably want something similar to:
40G is either 4 x 10G over a single pair, or broken out into 8 fibers in the
short or parallel versions.
Almost all Ethernet platforms support running most or all of their 40G ports as
1 x 40 or 4 x 10.
When using the breakout cables though your options are usually more limited. A

Hello all,
I'm a bit out of my element on this one and hoping someone can help.
I'm putting together an aut-num entry for RADB and have a question about our
Comcast peerings.
We peer with AS7922 in several sites, but if you look at the actual pathing via
bgp.he.net or just the routes
I may need to clarify that I do not want to break the port into 4x10G as
such. To the switch this will be an ordinary 40G link to another switch far
away.

Hello
Is it possible to reform a 40G signal as individual 10G links?
The idea is to use a 40G QSFP multimode MTP module such as
https://www.fs.com/products/44058.html. Then connect it using a MTP
breakout cable such as https://www.fs.com/products/68049.html to get
four dual fiber connectors.
