Thank you, Thompson. Non-GAAP revenue for the fourth quarter was $58.9 million, which was in line with our guidance range of $56 million to $63 million. Our datacenter revenue came in at $42.6 million, compared with $62 million in Q4 of last year. In the quarter, 60% of our datacenter revenue was derived from our 100G datacenter products and 38% was from our 40G products. Our production capacity remained constrained in the quarter due to the additional product testing steps. We implemented last quarter to screen for any potentially troublesome laser devices from our inventory, including work-in-process. As discussed last quarter, we identified and remedied the root cause of the problem that affected a small number of our lasers and we added additional testing steps including temporary steps to screen existing inventory. We remain on track to return to normal lead times by the end of this quarter. This quarter we also issued a $900,000 credit to a customer. We expect this credit to be non-recurring and have therefore adjusted it out of our GAAP revenue. As Thompson mentioned based on conversations with our hyperscale datacenter customers, we believe there was some inventory build-up in the supply chain as customers transitioned to 100G. We believe this will obfuscate demand and visibility in 2019. We currently expect demand in the first two quarters of the year will be sequentially down from our most recent quarters. We currently expect the second half of the year to improve over the first; however, we are still early in the year and visibility is limited. We continue to shift to and have good relationships with all of our hyperscale customers and believe we are in a solid position to expand our business with them when market conditions improve. We continue to have strong technical engagement with our customers and are making good progress on developing our next generation of datacenter products. Last month, we announced the release of a silicon photonics-based 400G optical module that is now currently available for customer sampling. These modules adhere to the requirements of onboard optics and incorporates several new technologies, including, an advanced silicon photonics-based optical subassembly that is the result of years of R&D effort by AOI and our technology partners. This next generation module is significant because the suite of technologies it incorporates will enable future similar modules to scale beyond 400G ultimately to 1.6 terabits per second, thereby enabling continued scaling of our customer's infrastructure. We gathered very positive feedback while demonstrating early prototypes at the European conference on Optical Communications last year and look forward to seeing the customer response after showcasing this technology at OFC next month. We believe the new and innovative technologies that we have developed and cost reduction efforts position us well to continue to expand the reach of our products to a broad group of datacenter customers, and diversify our customer base. While we will always rely on a relatively concentrated number of customers, diversifying our customer base remains a top priority. In the quarter, we had three design wins, including one with a large U.S. based datacenter customer, which is a new customer to AOI. This brings our total number of design wins to 26 for the year, including 12 with new customers to AOI. This exceeds our 2017 totals in both number of design wins and new customer wins demonstrating the effectiveness of our continuing efforts to diversify our customer base. In our cable television business, we remain encouraged by the customer activity in this market. We generated revenue of $12.7 million, compared with $14.3 million reported in Q4 of last year. This was a result of some weakness in demand mainly in Europe and Asia, partially offset by demand from North American MSOs. In the quarter, we started to ship volume orders for our Remote PHY product and we remain in active qualification trials with four additional customers with this technology. Our telecom products delivered revenue of $2.8 million, compared with $3.2 million in Q4 of last year. For the quarter 72% of our revenue was from datacenter products, 21% from CATV products with the remaining 7% from FTTH, telecom and other. In the quarter, we had 4 10% or greater customers; 3 in the datacenter business that contributed 38%, 18% and 11% of total revenue respectively, and one in the CATV business that contributed 11% of total revenue. For the year 2018, these same four customers represented 39%, 22%, 12% and 10% respectively of total revenue. Moving beyond revenue, in the quarter, we generated gross margin of 24.7% compared with a 34% recorded last quarter. Our gross margin came in below our expectations due to higher than anticipated costs incurred while we worked to resolve the inventory issue we experienced last quarter. Looking ahead, we expect gross margin to improve gradually starting this quarter. Total operating expenses in the quarter were $18.7 million or 31.8% of revenue compared with $22.8 million or 40.4% of revenue in the prior quarter. In the quarter, our operating expenses decreased sequentially due to lower bonus accruals as a result of our performance in the year. Operating loss in Q4 was $4.2 million, compared with an operating loss of $3.6 million in the prior quarter. Non-GAAP net loss after tax for the fourth quarter was $0.5 million or loss of $0.02 per basic share, compared with a net income of $17.9 million or $0.89 per diluted share in Q4 of 2017. GAAP net loss for Q4 was $8.6 million or a loss of $0.43 per basic share compared with the GAAP net income of $5.7 million or $0.28 per diluted share in Q4 of last year. The basic shares outstanding used for computing the net loss in Q4 were $19.8 million shares. Turning now to the balance sheet, we ended Q4 with $58 million in total cash, cash equivalents, short-term investments and restricted cash, compared with $64.1 million at the end of the previous quarter. As of December 31, we had $93.3 million in the inventory, a decrease from $107.9 million in Q3. Our cash balance reflects the use of approximately $11.6 million in cash to fund operations during the quarter. We made a total of $19.6 in capital investments in the quarter, including $17.2 million in production equipment and machinery and $1.6 million on construction and building improvements. This brings our total capital investments for the year to approximately $77.4 million, which was below our most recent $90 million CapEx forecast as we reduced purchases of certain equipment to maintain production volume in line with demand, all at the same time investing in the additional testing equipment needed to meet the new testing requirements implemented last quarter. Looking ahead, we expect capital expenditures in 2019 to be approximately $56 million, which factors in a continuation of the construction of our new factory in China. We continue to monitor end market conditions and may adjust our spending plans as necessary. Our total debt at year end was $84 million, up from approximately $50 million at the end of 2017. Much of this debt is associated with our capital expansion activities with maturities extending out several years. Just as we continuously monitor our spending plans to match market conditions, we regularly assess our capital structure to ensure we have the right mix of funding for current operations and future expansion. Moving now to our Q1 outlook, we expect Q1 revenue to be between $50 million and $55 million. We expect Q1 non-GAAP gross margin to be in the range of 26.5% to 28.5%. Net loss is expected to be in the range of $3.7 million to $5.8 million, and non-GAAP loss per share between $0.18 per share and $0.29 per share, using a weighted average basic share count of approximately 19.9 million shares. We expect our Q1 effective tax rate on our non-GAAP net income to be between 32% and 40%. With that, I will turn it back over to the operator for the Q&A session. Operator?
