TJ,
The big issue with what I am reading from you is that the carrier is
going to hand you an OTU4 with the waves muxed on to it. Your best luck
would be to use the same equipment they are using on the other end. At
the very least you need to know what it is and what timeslot
configuration it uses to make certain what you are using is compatible.
Not all equipment uses the same standard. Your best luck would be the
ribbon or the ciena more than likely. Getting ciena is hard right now so
pricing can be steep even for grey market gear. Id say ballpark
greymarket for a 7 slot chassis and cards 10-15k.
Least expensive way would be if you could convince them to hand them to
you as colored channels on a passive MUX. I haven't had too much luck
with that except with carriers I have a people I know in the engineering
departments.

Its pretty easy however most Ethernet switches won't accept OTU4.
Some exceptions like nokia 7250 IXR-10/6. However just about every
DWDM vendor has hardware that will do it. I Don't think
fiberstore has 100G muxponders.

I haven’t done it….but my impression is a dual mode QSFP28 such
as the above can connect OTU4 to an ethernet switch. There are
cheaper ones out there than FS. There’s now a Mikrotik with
QSFP28 ports…..and probably other low cost vendors are getting
into it as well.
So I believe you could get one of these dual mode transceivers
into a switch or router of choice and then use SFP+ for your 10g
paths.
Again, haven’t actually encountered OTU4 in the wild, I hope some
smart guy will correct me if I’m mistaken.

*Subject:* [AFMUG] OTU4 equipment?
What are some of the more 'inexpensive' ways to break a OTU4
carrier down to multiple 10g ethernet? Looking at aggregating a
bunch of 10g waves back to our DC on a single XC using OTU4
provided by the carrier?
