Thank you, Thompson. As Thompson mentioned, we delivered revenue and non-GAAP EPS in line with our expectations and gross margin below our expectations, mostly due to unfavorable product mix and unanticipated supply chain and logistics costs. During the quarter, we continued to see strong demand in the CATV market and improving conditions in the data center market. As we anticipated, our results were adversely impacted by approximately $3 million due to the well known component shortages and supply chain disruptions. Currently, we believe that supply constraints are easing and do not anticipate revenue shortfall in the first quarter due to an inability to source necessary raw materials. We do believe, however, that pricing and shipping costs on many of these components will remain elevated for some time, and this will negatively impact margins in the quarter. Turning to our quarterly performance. We secured four new design wins among four customers. Of the four design wins, two were with data center customers and two were with telecom customers. One of the data center design wins was our first for 400G products and was with an existing data center customer. This customer is currently purchasing 100G products from AOI and has placed an initial volume order for its earliest 400G deployments. We are pleased to report that this customer has chosen AOI as the primary supplier for its 400G data center transceiver needs. Total fourth quarter revenue of $54.4 million, increased 3.1% compared to the fourth quarter of 2020 and increased 2.1% sequentially. Our Q4 revenue was at the upper end of our guidance range of $51 million to $55 million. In the fourth quarter, 46% of our revenue was from our data center products, 46% from CATV products, with the remaining 8% from FTTH, telecom and other. In our CATV products segment, the overall demand environment remains exceptionally strong as MSOs, particularly in North America, continue to upgrade their networks. We generated revenue of $24.9 million, up 56.4% year-over-year and up 7.9% sequentially. Looking ahead, we continue to have good visibility with CATV orders as we currently have an unprecedented order backlog extending into Q4 of this year. We believe that conditions in our CATV market are likely to remain highly favorable into 2023 because our products are currently being used in network upgrade projects by the three largest CATV MSOs in the US along with other smaller operators. In general, these network upgrades are still in their early phases, and all of the projects are currently expected to continue well into 2023 or beyond. Our Q4 data center revenue came in at $25.2 million, down 23.1% year-over-year and up 5.3% sequentially. In the fourth quarter, 14% of our data center revenue was from our 40G transceiver products, 79% was from our 100G products and 0.4% was from our 200G and 400G transceiver products. We are very pleased to have begun volume shipments of our 400G portfolio as these products have been under qualification by 11 different customers and the first design wins and associated volume orders give us increased confidence in our traction within the 400G data center market. While we begin shipments of 400G, we are also preparing our first 800G samples, which we expect to deliver to the first of our interested customers at the end of next month. And we have begun concept discussions with several customers on ideas beyond 800G, including 1.6 terabits per second. So we can see a clear progression of increasing data rate products being developed by AOI and customer interest in these future product activities remains fine. Now turning to our telecom segment. Revenue from our telecom products of $3.3 million was down 5.8% year-over-year and declined 36.1% sequentially. In line with our expectations, we saw continued volatility in market conditions in the China telecom market with respect to 5G rollouts. Looking ahead, we continue to expect quarter-to-quarter variability until the pace of 5G rollouts in China becomes more predictable. For the fourth quarter, our top 10 customers represented 88.4% of revenue, up from 85.1% in Q4 of the prior year. We had three 10% or greater customers in the fourth quarter, one in the CATV market and two in the data center market. These customers contributed 36.1%, 15% and 12.4% of total revenue, respectively. For the full year, we had three 10% or greater customers, two in the CATV market and one in the data center market. These customers contributed 25.6%, 14.1% and 11.9% of revenue, respectively. In Q4, we generated non-GAAP gross margin of 17.6%, which was below our guidance range of 18.5% to 20% and was down from 19.9% in Q3 of 2021 and 27.5% in Q4 of 2020. The decline in our gross margin was mostly due to unfavorable product mix and increased costs from component shortages. As we discussed last quarter, we have experienced price pressure on certain of our 100G data center products as these product lines have reached full maturity and 400G editions have begun. In addition, in our CATV segment, we have seen an inventory correction on some of our higher margin products by one of our customers that has significantly reduced orders for these higher-margin products. These product mix issues overlap with well-known supply chain challenges and increases in shipping costs that also provide a margin headwind. Finally, we've reduced production of lasers in our fab in Q4 due to slower demand from the China 5G market as well as managing inventory ahead of the Lunar New Year. This reduction in fab output resulted in under absorption of the fixed cost of running the fab and further pressured our margins. We believe most of these impacts are transitory. While 100G margins are likely to continue to remain pressured, we expect these products to represent a smaller contribution to data center revenue as 400G begins its ramp, and we begin to see cost reduction associated with the transition to volume production. On the CATV front, we have a number of cost reduction efforts that have been implemented to reduce raw material and production costs for our highest volume products. In addition, we expect the unfavorable mix shift due to the inventory correction mentioned above to ease by mid-year. While we expect margins in Q1 to continue to be pressured by many of the factors I've already discussed and additionally by the effects of Lunar New Year on our Asian operations, Q2 and beyond currently looks significantly more favorable in terms of gross margin as these headwinds moderate or eliminated altogether. Total non-GAAP operating expenses in the fourth quarter were $16.9 million or 31% of revenue compared with $20.6 million or 39% of revenue in Q4 of the prior year. The reduction in operating expenses is due to a decrease in R&D spend as some of the costs associated with our 400G development have begun to subside, along with benefits from certain cost reduction efforts we made during the quarter. Operating expenses were further improved by careful cost control, along with a significant reversal of previously accrued bonuses, especially to executives, which occurred in Q4. We anticipate continued disciplined cost control until a return to consistent profitability has been demonstrated. While we intend to carefully control operating expenses, we continue to invest in new product development. In addition to the 800G and 1.6 terabit transceiver work I discussed earlier for our data center customers, we also have been actively developing high-power lasers intended for use in LiDAR and other sensing applications. These LiDAR lasers have applications in automotive driver assistance systems, security monitoring, augmented reality and other 3D sensing systems. These products have been under development for several years now. And within the last few months, we have begun shipping qualification samples to eight different customers, most of which are in the automotive space. Initial feedback from these customers has been very positive, further reinforcing our conviction that AOI's laser-related R&D remains at the forefront of new technology, both in our data center market and in new markets like automotive. While meaningful revenue for these LiDAR lasers is likely a year or two away, the addition of these products continues the trend of greater diversity within our customer base. As many of you know, increasing revenue diversity has been a key element of our risk reduction strategy for more than 3 years. Non-GAAP operating loss in the fourth quarter was $7.3 million compared to an operating loss of $6.1 million in Q4 of the prior year. GAAP net loss for Q4 was $14.5 million or a loss of $0.54 per basic share compared with a GAAP net loss of $13.4 million or a loss of $0.57 per basic share in Q4 of 2020. On a non-GAAP basis, net loss for Q4 was $5.5 million or a loss of $0.20 per basic share, which was in line with our guidance range of a loss of $5.5 million to $6.6 million or a loss per share in the range of $0.20 to $0.24 per basic share and compares to a net loss of $4.8 million or a loss of $0.20 per basic share in Q4 of the prior year. The basic shares outstanding used for computing the net loss in Q4 were 27.1 million. Turning now to the balance sheet. We ended the fourth quarter with $41.1 million in total cash, cash equivalents, short-term investments and restricted cash. This compares with $48.9 million at the end of the third quarter. Notably, we reduced total debt compared with Q3 by $5.8 million by utilizing less of our revolving lines of credit at year end. As of December 31, we had $92.5 million in inventory compared to $94.5 million at the end of Q3. Inventory decreased primarily due to utilization of inventory for customer orders. We made a total of $2.3 million in capital investments in the quarter, including $2.1 million in production equipment and machinery and $0.1 million in construction and building improvements. We are still in the process of evaluating our CapEx plans for 2022, and we will share our expectations as soon as we complete our analysis. Moving now to our Q1 outlook. We expect Q1 revenue to be between $51 million and $54 million and non-GAAP gross margin to be in the range of 15.5% to 17.5%. Non-GAAP net loss is expected to be in the range of $8.3 million to $9.5 million and non-GAAP loss per basic share between $0.30 and $0.35 using a weighted average basic share count of approximately 27.5 million shares. With that, I'll turn it back over to the operator for the Q&A session.
