Network and communications chips supplier Airoha Technology Corp (達發科技) on Tuesday said revenue from chips used in high-speed optical transceivers for data centers would triple this year, driven by global artificial intelligence (AI) infrastructure buildout.
Airoha has strong confidence in digital signal processors (DSPs), given its better-than-expected shipments and a surge in sales in the first quarter, Airoha executive vice president M.H. Shieh (謝孟翰) said at an earnings conference.
The robust growth is expected to sustain throughout the year, thanks to replacement demand and systems upgrading to chips with higher speeds and wider bandwidths, Shieh said.

The company plans to roll out new DSPs that can transmit 100 gigabits of data per second in the middle of this year, and is working on next-generation DSPs that can transmit 200 gigabits of data per second, he said.
Airoha expects DSPs and chips used in optical transceivers and chips used in satellites and AI data centers to account for a high single-digit percentage of its total revenue this year, from a low-single-digit percentage last year, Shieh said.
While Nvidia Corp plans to adopt copackaged optics (CPO) technology for new AI servers, Airoha believes DSP-based pluggable optical transceivers remain the mainstream solution for AI data center operators, given their operating flexibility, signal reliability and better total ownership costs, he said.
By 2030, pluggable optical transceivers powered by 400 gigabit to 1.6 terabit DSPs would remain the top choice of cloud service providers, he added.
The two technologies are complementary, rather than competitive, Shieh said.
DSP-based solutions are suitable for “scaling out” data transmission and connectivity between servers within a large-scale AI data center, while CPO is good at “scaling up” a server rack, he said.
In the first quarter, Airoha’s revenue rose 4.4 percent annually and 20 percent quarterly to NT$5.46 billion (US$173.4 million).
DSPs, Ethernet chips and broadband chips accounted for about half of Airoha’s total revenue, with wireless chips such as Bluetooth and Wi-Fi chips contributing to the other half.
Net profit grew 2.5 percent year-on-year and 34.8 percent quarter-on-quarter to NT$748 million.
Earnings per share rose to NT$4.47 from NT$4.36 a year ago and NT$3.32 the previous quarter.
Starlux Airlines Co (星宇航空) today unveiled a long-haul network expansion plan at a shareholders’ meeting in Taipei, including direct flights to Barcelona, Spain, and Zurich, Switzerland, as well as a service connecting Taipei, Sydney and New Zealand. Starlux is to become the first Taiwanese carrier to offer non-stop services to the two European cities, while the inaugural oceanic route is expected to expand transit opportunities within the Australia-New Zealand market, Starlux said. Flight services to Chicago, Dallas, Washington and New York are under evaluation, the airline added. Prior to the shareholders’ meeting, the airline earlier this year announced that it would be
Netherlands-based semiconductor equipment supplier ASML Holding NV yesterday said that it is planning to hire an additional 1,000 people in Taiwan this year in response to growing demand from clients. ASML had previously planned to recruit 600 people this year, but that the plan has been adjusted upward, ASML vice president and ASML Taiwan general manager Grace Wang (汪佳慧) told reporters. ASML has a workforce of more than 4,500 in Taiwan, accounting for about 10 percent of its global total, Wang said. This year’s recruitment campaign would focus on adding people in the customer support, manufacturing and supply chain domains to assist ASML
UNDER MICROSCOPE: Taiwan detained three people who allegedly conspired to buy servers in Taiwan and export them using fraudulent documentation, prosecutors said Nvidia Corp chief executive officer Jensen Huang (黃仁勳) on Saturday urged Super Micro Computer Inc to tighten up on compliance after Taiwan detained three people this week for allegedly making fraudulent declarations about artificial intelligence (AI) servers made by its US partner. The development marked the nation’s first crackdown on semiconductor smuggling, which grew after the US slapped restrictions on exports of high-end chips such as Nvidia AI accelerators to China. Nvidia is “rigorous” in explaining regulations to all of its partners, Huang told reporters after arriving in Taipei. “Ultimately Super Micro has to run their own company,” he said in response to
Nvidia Corp yesterday announced that CEO Jensen Huang (黃仁勳) would attend an employee meeting in Taipei tomorrow to celebrate the launch of the company’s Taiwan headquarters project. Huang would attend a gathering at the site of Nvidia’s planned headquarters in Beitou Shilin Technology Park (北投士林科技園區), the company said in a statement. After arriving in Taiwan on Saturday last week, Huang told reporters that he plans to meet with Quanta Computer Inc (廣達) chairman Barry Lam (林百里) and Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) chairman C.C. Wei (魏哲家), and would attend the groundbreaking ceremony for Nvidia’s Taiwan headquarters tomorrow. Nvidia has not yet applied
