Weishibo (威世波) was founded in 2005 and has long focused on the research, manufacturing, and sales of high-speed optical communication and network communication products, according to a report by United Daily News (UDN). Its main product lines include Optical Transceiver Modules, Active Optical Cables (AOC), Direct Attach Cables (DAC), External Light Source modules (ELS), and Continuous Wave (CW) Laser Chips (E8).
According to CNA, Weishibo will list on the TPEx Emerging Board on July 16 (E1). The company's paid-in capital stands at NT$338 million, and the lead underwriter for the listing is Yuanta Securities (E3).
Weishibo Chairman Chen Xiao-sheng (陳曉昇) said, as quoted by CNA, that fast-growing AI computing demand is pushing high-speed optical communication from 400G toward 800G and 1.6T generations. He said Weishibo is centering its strategy on CW Lasers, combined with External Light Source (ELS) modules and high-speed optical modules, to build the core light source for AI data center optical engines as it pursues the high-speed optical interconnect opportunity (E2).
According to UDN, Chairman Chen said Weishibo has completed product development covering CW Lasers from 70mW up to above 400mW, capable of supporting 800G, 1.6T, and future higher-speed optical communication applications (E10). The following breakdown, based on the same UDN report, shows the staged rollout:
| Power Level | Status | Timeline |
|---|---|---|
| 70mW / 100mW | In customer validation | Shipping expected Q4 2026 |
| 200mW | Under continued development | Not specified |
| 400mW+ | Planned mass production | 2027 |
(E10)
According to CNA, Weishibo operates a vertically integrated model spanning wafer design, key light source components, and high-speed optical communication module manufacturing, which the company says gives it control over core technology, supply chain, and cost competitiveness. The company has self-developed Distributed Feedback (DFB) lasers, high-power Continuous Wave lasers, and high-speed optical communication key components, which are currently applied in optical transceiver modules and Bidirectional Optical Sub-Assemblies (BOSA) (E6).
CNA reports that, in response to continued growth in AI data center and high-speed optical communication market demand, Weishibo has launched construction of a new plant in Zhongli, expected to begin production this October. Beyond expanding business and R&D space, the new plant will also serve as an important production base for the company's high-end products (E7).
Both CNA and UDN report consistent figures on Weishibo's recent financial trajectory. Consolidated revenue rose from NT$298 million in 2024 to NT$733 million in 2025, a 146.3% year-on-year increase. Operating income for 2025 reached NT$11.66 million, up 129.4%, while net income attributable to the parent company came to NT$6.72 million, up 201.4%. Earnings per share (EPS) for 2025 stood at NT$0.23 (E4, E9). For the first quarter of 2026, consolidated revenue reached NT$232 million, up 98.3% year-on-year, which CNA attributes to continued growth in high-speed optical communication product shipments (E5).
| Metric | 2024 | 2025 | YoY Change | 2026 Q1 |
|---|---|---|---|---|
| Consolidated Revenue | NT$298 million | NT$733 million | +146.3% | NT$232 million (+98.3% YoY) |
| Operating Income | — | NT$11.66 million | +129.4% | — |

| EPS | — | NT$0.23 | — | — |
(E4, E5, E9)
The reported figures show Weishibo's revenue growth accelerating alongside its stated shift toward higher-speed optical communication products: 2025 revenue growth of 146.3% was followed by a further 98.3% year-on-year increase in Q1 2026 (E4, E5, E9). This timing aligns with Chairman Chen's description of demand moving from 400G toward 800G and 1.6T (E2), and with the staged CW Laser rollout in which 70mW and 100mW products are set to ship in Q4 2026 — the same quarter the Zhongli plant is expected to begin production (E7, E10). Whether the new plant's capacity and the higher-power CW Laser lines translate into further revenue gains is not addressed in the available reporting.
According to UDN, these products are currently in customer validation and are expected to begin shipping in the fourth quarter of 2026 (E10).
According to CNA, Weishibo's paid-in capital is NT$338 million, and Yuanta Securities is the lead underwriter for the Emerging Board listing (E3).
According to a report by TechNews (2026-07-14), Intel announced a €5 billion (about US$5.7 billion) investment to modernize its Leixlip, Ireland fab for Intel 3-based Xeon 6 and next-generation Xeon processors. The announcement follows a 2024 global 15% headcount cut that included a voluntary severance program at the same site, according to BusinessNext (bnext.com.tw).
According to TheLec and Tom's Hardware, Samsung Electronics' foundry division has completed tape-out of Tesla's AI5 autonomous-driving chip on a 2nm-class process at its Taylor, Texas fab, with mass production planned for next year — several months after the TSMC version reportedly taped out first.
According to Inside.com.tw and CNYES, Tesla's next-generation AI5 chip has completed tape-out and will be built on Samsung's 2nm process at the Taylor, Texas fab, with production split between Samsung and TSMC as Samsung's non-memory division reported a roughly KRW 600 billion loss in Q2.
