NEW YORK Feb 2 (Reuters) - Shares of NeoPhotonics Corp (NPTN.N) jumped 20.5 percent in their stock market debut on Wednesday as the integrated circuit company became the latest publicly-traded stock in a hot sector.

The shares closed at $13.25 on the New York Stock Exchange after climbing as high as $14.40, or 30.9 percent above the $11 initial public offering price.

Formerly known as NanoGram Corp, NeoPhotonics is a San Jose, California-based maker of photonic integrated circuit-based modules and subsystems for high-speed communications networks that require a lot of bandwidth.

"They are in an overall growth market," said Francis Gaskins, president of IPODesktop.com.

NeoPhotonics offers more than 300 products that help streamline high-speed data transmission and efficient bandwidth allocation over communications networks.

Smartphones, netbooks, tablet computers and gaming devices are using increasingly more bandwidth for content such as high-definition and 3-D video, music, social networking and other multimedia applications.

NeoPhotonics sells products to global network equipment vendors including Cisco Systems Inc (CSCO.O), Huawei Technologies Co [HWT.UL], Nokia Siemens Networks [NOKI.UL] and Mitsubishi Electric Corp (6503.T), according to a filing with U.S. regulators.

The firm's revenue grew to $132.9 million in the nine months ended Sept. 30, 2010, up 18.6 percent from the same period a year earlier. The company broke even for common shareholders, after posting a loss of $4.09 per share in the first nine months of 2009.

As of September 30, NeoPhotonics had an accumulated deficit of $216.1 million, the filing showed.

NeoPhotonics raised around $82.5 million in its IPO on Tuesday, selling 7.5 million shares for $11 each. It had originally planned to sell 7 million shares for $9 to $11 each.

The company said it planned to use the proceeds to expand and possibly acquire other businesses, products, services or technologies, although it said no specific agreements or commitments had been made.

Underwriters on the offering, led by Bank of America Merrill Lynch and Deutsche Bank Securities, have an option to buy up to 1.1 million additional shares.
