NeoPhotonics Corp. (NYSE: NPTN) announced Thursday that it's planning to acquire privately held optical components vendor Santur Corp.

NeoPhotonics is offering about US$39.2 million plus possibly another $7.5 million contingent on Santur's performance. Santur's revenues were $21 million for the six months ending June 30, according to NeoPhotonics.

The deal is expected to close by year's end.

Why this matters
Suppliers are gearing up for the 100Gbit/s product cycle, and NeoPhotonics is no exception. The deal would give NeoPhotonics, which stakes its name on photonic integration, some 100Gbit/s-related indium phosphide (InP) piece-parts to integrate.

It also gives NeoPhotonics an easy way into the 10x10 multisource agreement (MSA). Santur was an early champion of the transceiver format, which is an alternative to telecom's 100Gbit/s standards and has the backing of some big customers including Brocade Communications Systems Inc. (Nasdaq: BRCD) and Google (Nasdaq: GOOG).

Santur also has coherent 100Gbit/s optics, according to the NeoPhotonics press release.

Separately: So much for that IPO -- Santur's, that is. The company strove to go public years ago but couldn't get it done. While $46.7 million is nothing to sneeze at, Santur raised at least $108 million in its 12-year lifetime, by Light Reading's count.
