I like:

"Directly Modulated Lasers (DML) from Sanan Integrated Circuits (SAIC), which has incorporated POET’s interposer compatibility requirements into their line of LR4 DML lasers."

Are the hurdles to incorporate so small or are the expectations so big? Whatever, that´s a good sign.

I like not that much:

"...the cost of the optical engine allowing us to provide a savings to customers in the range of 25%."

"...we are able to design an optical engine that uses 10% to 15% less power..."

I remember bigger numers when the platform in its entirety was described, especially about power consumption. But what do I know about 100 G long reach engines...
