Critical Accounting Policies and Estimates

Stock-based Compensation Expense

Stock-based compensation expense recognized under SFAS 123(R) for the three and six months ended June 30, 2008 was $0.05 million and $0.1 million, respectively, determined by the Binomial Lattice valuation model, and represents stock-based compensation expense related to employee stock options. As of June 30, 2008, total unrecognized compensation costs related to unnvested stock options was $0.2 million, which is expected to be recognized as an expense over a weighted average period of approximately 2.0 years.

For additional information regarding our critical accounting policies and estimates, see the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2007.

Overview

We were founded in December 1995 and commenced operations to design, manufacture and market fiber optic interconnect products, which we call our connectivity products. We started selling our optical passive products in July 2000.

Since introduction, sales of optical passive products have fluctuated with the overall market for these products.

Our optical passive products contributed revenues of $3.6 million and $3.1 million for the three months ended June 30, 2008 and 2007, respectively. In the three months ended June 30, 2008 and 2007, our top 10 customers comprised 67.6% and 57.6% of our revenues, respectively. For the three months ended June 30, 2008, two customers accounted for 18.0% and 10.9% of our total revenues. For the three months ended June 30, 2007, one customer accounted for 22.6% of our total revenues. We market and sell our products predominantly through our direct sales force.

Our cost of revenues consists of raw materials, components, direct labor, manufacturing overhead and production start-up costs. We expect that our cost of revenues as a percentage of revenues will fluctuate from period to period based on a number of factors including:

· changes in manufacturing volume;

· costs incurred in establishing additional manufacturing lines and facilities;

· inventory write-downs and impairment charges related to manufacturing assets;

· mix of products sold;

· changes in our pricing and pricing from our competitors;

· mix of sales channels through which our products are sold; and

· mix of domestic and international sales.

Research and development expenses consist primarily of salaries and related personnel expenses, fees paid to outside service providers, materials costs, test units, facilities, overhead and other expenses related to the design, development, testing and enhancement of our products. We expense our research and development costs as they are incurred. We believe that a significant level of investment for product research and development is required to remain competitive.

Sales and marketing expenses consist primarily of salaries, commissions and related expenses for personnel engaged in marketing, sales and technical support functions, as well as costs associated with trade shows, promotional activities and travel expenses. We intend to continue to invest in our sales and marketing efforts, both domestically and internationally, in order to increase market awareness and to generate sales of our products. However, we cannot be certain that our expenditures will result in higher revenues. In addition, we believe that our future success depends upon establishing successful relationships with a variety of key customers.

General and administrative expenses consist primarily of salaries and related expenses for executive, finance, administrative, accounting and human resources personnel, insurance and professional fees for legal and accounting support.

Revenues. Revenues were $10.3 million and $8.7 million for the three months ended June 30, 2008 and 2007, respectively. Revenues increased 18.6% in the three months ended June 30, 2008 from the same period in 2007, as a result of a broad base increase in demand from our customers, especially for Datacenter related products from our Premise Market customers. Revenues were $19.7 million and $15.4 million for the six months ended June 30, 2008 and 2007, respectively. Revenues increased 28.1% in the six months ended June 30, 2008 from the same period in 2007, mainly due to a large telecom product contract for our optical passive and connectivity products and increased volume shipments of our optical passive and connectivity products for telecom and cable television applications.

Cost of Revenues. Cost of revenues was $7.1 million and $5.9 million for the three months ended June 30, 2008 and 2007, respectively. Cost of revenues as a percentage of revenues increased to 68.5% for the three months ended June 30, 2008 from 68.1% for the three months ended June 30, 2007. Cost of revenues was $13.5 million and $10.5 million for the six months ended June 30, 2008 and 2007, respectively. Cost of revenues as a percentage of revenues increased to 68.6% for the six months ended June 30, 2008 from 68.4% for the six months ended June 30, 2007. The higher cost of revenues as a percentage of revenues for the period ended June 30, 2008 was due to increased sales of optical passive products, which have lower gross margins.

Gross Profit. Gross profit increased in dollars to $3.3 million, or 31.5% of revenues, for the three months ended June 30, 2008 from $2.8 million, or 31.9% of revenues, for the same period in 2007. Gross profit increased to $6.2 million, or 31.4% of revenues, for the six months ended June 30, 2008 from $4.9 million, or 31.6% of revenues, for the same period in 2007. For the period ended June 30, 2008, the higher utilization of our factories as a result of increased volume shipments of our products were offset to some extent by increased sales of optical passive products which have lower gross margins.

Research and Development Expenses. Research and development expenses increased to $0.9 million for the three months ended June 30, 2008 from $0.8 million for the same period in 2007. Research and development expenses increased to $1.8 million for the six months ended June 30, 2008 from $1.5 million for the same period in 2007. The increase was primarily due to costs associated with new product development. As a percentage of revenues, research and development expenses decreased to 8.7% in the three months ended June 30, 2008 from 9.7% for the same period in 2007. As a percentage of revenues, research and development expenses decreased to 9.1% in the six months ended June 30, 2008 from 10.0% for the same period in 2007. We expect research and development expenses on our product development efforts to increase in the near term as we intend to continue to invest in our research and product development efforts.

General and Administrative Expenses. General and administrative expenses remained at $0.9 million for the three months ended June 30, 2008 and 2007, respectively. General and administrative expenses remained at $1.8 million for the six months ended June 30, 2008 and for the same period in 2007. As a percentage of revenues, general and administrative expenses decreased to 8.7% in the three months ended June 30, 2008 from 10.5% for the same period in 2007. As a percentage of revenues, general and administrative expenses decreased to 9.0% in the six months ended June 30, 2008 from 11.5% for the same period in 2007. We expect general and administrative expenses will remain relatively flat in the next two quarters.

Stock-Based Compensation. Total stock-based compensation decreased to $0.05 million for the three months ended June 30, 2008 from $0.1 million for the same period in 2007. Total stock-based compensation decreased to $0.1 million for the six months ended June 30, 2008 from $0.2 million for the same period in 2007. These decreases were due to fewer unvested stock options to date in 2008.

Interest and Other Income, Net. Interest and other income, net, was $0.3 million and $0.5 million for the three months ended June 30, 2008 and 2007, respectively. Interest and other income, net, was $0.7 million and $0.9 million for the six months ended June 30, 2008 and 2007, respectively.

Income Tax Expense. During the three months ended March 31, 2008, we paid $0.05 million income tax for the year ended December 31, 2007. Income tax expense was approximately $0.02 million and $0.03 million for the three months and six months ended June 30, 2008. We did not incur income tax expense for the three months and six months ended June 30, 2007 because we utilized tax credits due to our accumulated deficit.

Liquidity and Capital Resources

At June 30, 2008, we had cash and cash equivalents of $16.3 million and short-term investments of $4.8 million. On March 31, 2008, we reclassified $15.6 million of auction rate securities collateralized by student loans and substantially guaranteed by the U.S. Department of Education from short-term investments into long-term investments. During the three months ended June 30, 2008, the Company recorded an unrealized loss of $0.2 million on these securities. At June 30, 2008, we had long-term investments of $15.4 million. Continued auction failures could adversely impact our liquidity as we may not be able to sell these securities when we want to and may have to hold them until maturity between 2032 and 2046.

Net cash provided by operating activities was $0.9 million for the six months ended June 30, 2008. Net cash provided by operating activities was primarily due to net income of $1.9 million, an increase in accounts payable of $0.9 million, and total depreciation and amortization expenses of $0.6 million, which was offset by a $1.3 million increase in accounts receivable, a $0.4 million decreased in inventory provision and a $0.6 million increase in inventory. Net cash provided by operating activities was $1.2 million for the six months ended June 30, 2007, and was primarily due to net income of $1.3 million, an increase in accounts payable of $0.9 million, and total depreciation and amortization expenses of $0.8 million, which was offset by a $1.1 million increase in accounts receivable, a $0.4 million decreased in inventory provision and a $0.4 million increase in inventory.

Cash provided by financing activities was $0.3 million for each of the six months ended June 30, 2008 and 2007, resulting from proceeds from the exercise of options to purchase our common stock and common stock issued through our Employee Stock Purchase Plan. Cash used in financing activities was $0.08 million and $0.05 million for the six months ended June 30, 2008 and 2007, respectively, and was used for repayment of bank borrowings.

We believe that our current cash, cash equivalents and short-term investments will be sufficient to meet our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. However, our future growth, including any potential acquisitions, may require additional funding. If cash generated from operations is insufficient to satisfy our long-term liquidity requirements, we may need to raise capital through additional equity or debt financings, additional credit facilities, strategic relationships or other arrangements. If additional funds are raised through the issuance of securities, these securities could have rights, preferences and privileges senior to holders of common stock, and the terms of any debt facility could impose restrictions on our operations. The sale of additional equity or debt securities could result in additional dilution to our stockholders, and additional financing may not be available in amounts or on terms acceptable to us, if at all. If we are unable to obtain additional financing, we may be required to reduce the scope of our planned product development and marketing efforts. Strategic arrangements, if necessary to raise additional funds, may require us to relinquish our rights to certain of our technologies or products. Our failure to raise capital when needed could harm our business, financial condition and operating results.

Contractual Obligations

Our corporate headquarters are in Sunnyvale, California where we lease a 34,800 square foot facility from a third party for a current monthly rent of approximately $33,000. The lease has a six-year term commencing on July 22, 2004.

In December 2000, we purchased approximately 8,200 square feet of space immediately adjacent to our leased facility in Tu-Cheng City, Taiwan for $0.8 million. Additionally, in February 2006, we entered into a new lease for a total of 21,600 square feet in a facility located in Hu-Kou, Taiwan. This lease will expire in January 2009.

In July 2007, we renewed the lease for our 62,000 square feet facility in the Shenzhen area of China, which will expire in July 2012. Additionally, in February 2007, we entered into a new lease for an 8,200 square feet dormitory in Shenzhen, which lease will expire in January 2012.
