It sounds as if he is contradicting himself, (apparently they are stuck on/with the MXC (currently Multi Mode only) and Corning clear curve Multi but then says “, I now have a 50-micron multi-mode fibre and couple it down into a silicon photonic chip; that is the hard part.”

As info Corning makes a single mode clear curve also but,,,,,, read the last sentence of the last 2 paragraphs.

"The company is using multi-mode fibre for its silicon photonics solution despite growing interest in single-mode fibre to meet the longer reach requirements emerging in the data center.

Intel chose multi-mode as it results in a more economic solution in terms of packaging, assembly and cabling. "If you look at a single-mode fibre solution - coupling the fibre, packaging and assembling - it is very expensive," he says. That is because single-mode fibre requires precise fibre alignment at the module and at the connector, he says: "Even if the photonics were free, packaging, testing and assembly accounts for 40-60 percent of cost."

Silicon photonics is inherently single-mode and making it work with multi-mode fibre is a challenge. “At the transmitter side it is somewhat easy, a small hose - the transmitter - going into a big hose, a 50-micron [multi-mode] fibre, so the alignment is easy,“ says Paniccia. “At the receiver side, I now have a 50-micron multi-mode fibre and couple it down into a silicon photonic chip; that is the hard part.”

Corning's ClearCurve multi-mode fibre and the MXC connector working with Intel's 100 Gigabit modules achieve a 300m reach, while 820m has been demonstrated. “At the end of the day, the customer will decide how do we drive a new architecture into the next-generation of data centre,” says Paniccia.

Oh, IMO Lightwave is working on single mode solutions/devices (80% sure).
