ClariPhy Pushes Toward 40G Volume

Chip maker ClariPhy Communications Inc. is announcing a new CEO Wednesday as it tries to do its part to ready the supply chains for coherent 40Gbit/s and 100Gbit/s optical networking.

The company has hired Nariman Yousefi, who tells Light Reading he was the twelfth employee at Broadcom Corp. (Nasdaq: BRCM). He oversaw Broadcom's networking division from the beginning, building it into a dominant force in the chip industry.

His job is to oversee ClariPhy's transition into volume manufacturing. Former CEO Paul Voois, a founder of the company, will stick around as a vice president, working in areas such as business development.

ClariPhy also says it's added US$4.5 million to the previously announced $14 million funding round. The money comes from an undisclosed systems vendor that had already chipped in as part of the $14 million. ClariPhy officials won't say how much they've raised in total, but by Light Reading's count, it comes to something like $82.5 million in nine years.

Why this matters
At least two OEMs are counting on ClariPhy for 40Gbit/s and 100Gbit/s digital signal processors (DSPs): Nokia Networks and one that remains undisclosed. Both OEMs were part of ClariPhy's $14 million round announced in June, and the latter provided the extra $4.5 million being announced Wednesday.

A solidifying of the supply chain is a necessary step toward getting 40Gbit/s and 100Gbit/s technology available in volumes and eventually pushing down prices. ClariPhy still isn't saying when it plans to produce DSPs for coherent 100Gbit/s, but Yousefi says the company expects to have 40Gbit/s chips out by the end of the year.
