Strategic investors have backed US-based telecoms equipment company ClariPhy Communications’ $24m of third round funding.
Nasdaq-listed equipment making peer Oclaro led the series C round for ClariPhy, and said it invested $7.5m.
The remainder of the C round came from undisclosed strategic investors and its existing venture capital backers Norwest Venture Partners, Allegis Capital, Onset Ventures and Pacific General Partners.
ClariPhy closed its series A round in February 2006 at $13m and held an undisclosed series B round in 2008.
Alain Couder, chief executive of Oclaro, said: "By investing in and partnering with ClariPhy, we believe we can offer our customers best-in-class electronics and optical technology."
Last year, Oclaro used ClariPhy’s product to boost the performance of its equipment for 10G phone networks.
