Inter-domain OTN, does it happen in the real world?
Reading about OTN networks, I see that "IrDI" is specified to handle the case where one OTN network needs to connect to another natively with OTN signals. Is this done in the real world? Does OTN network operator A ever go to OTN network operator B and say, "I'd like to buy a OTU2 from city X to city Y on your long haul network (at buildings J and K where we can connect simply with short-distance SMF/1310 signals), and what TCM levels can you give me?" I understand this in the case of lit 10GbE-WANPHY, LAN, and OC-192, but are OTU "lit" signals bought and sold wholesale this way too? Is there generally a price premium over the more normal client signals? -Will Orton
Most telcos can provide an OTU2 client interface but there is no peering, they are just mapping directly to a wavelength or to OTU3/4. So it's transparent service. Phil On Oct 23, 2012, at 7:07 PM, Will Orton <will@loopfree.net> wrote:

Will, I think you also need to consider the case where one operator runs more than one network. This can happen because of acquisition or administrative structure. I regret it might also happen because of vendor equipment compatibility/lock-in issues. Cheers, Adrian price
