<p>Addressing pain points such as the lack of PCIe slots in laptops, NUC mini PCs, mobile workstations, and industrial equipment—which prevents the expansion of 10 Gigabit SFP+ ports—as well as the need for both single- and dual-link solutions and inconsistent system compatibility, LeKuo has introduced two USB4-to-10Gb SFP+ fiber network adapter solutions: the DTB3F11 (single-port) and the DTB3F22 (dual-port). Both products are equipped with the Realtek RTL8127ATF 10Gb network chip, enabling high-speed 10Gb fiber network expansion for devices via the USB4 interface.</p><p><strong><span style="font-size:20px;">Analysis of the Core Architecture: Same RTL8127ATF Platform, Different Design Targets</span></strong></p><p class="paragraph text-align-type-left" style="margin-top: 4px; margin-bottom: 4px;"><span style="font-size:12pt"><span style="font-family:等线"><span class="image-wrapper" style="display: inline-block; width: 874px;"><span style="overflow:hidden"><span style="transform:rotate(0deg)"><span style="height:409.3358530183727px"><img id="5c6e4b87" data-cke-saved-src="https://wdcdn.qpic.cn/MTY4ODg1NTU5NzYwMDM2MA_447495_pc45NFmybljZG2Sr_1780908725?w=2358&h=1188&type=image/jpeg" src="https://wdcdn.qpic.cn/MTY4ODg1NTU5NzYwMDM2MA_447495_pc45NFmybljZG2Sr_1780908725?w=2358&h=1188&type=image/jpeg" style="margin-top:-31px; width:874px; height:440.335px" thumb="https://wdcdn.qpic.cn/MTY4ODg1NTU5NzYwMDM2MA_447495_pc45NFmybljZG2Sr_1780908725?imageMogr2/thumbnail/1600x806/ignore-error/1"/></span></span></span></span></span></span></p><p>Both products are equipped with the Realtek RTL8127ATF dedicated Ethernet chip, which is optimized for SFP+ 10 Gigabit optical ports.

Through differentiated interface designs, power supply solutions, and system compatibility, they precisely address the 10Gb fiber network upgrade needs of different users:</p><p>● For portability and single-link requirements: The DTB3F11 is the top choice, featuring ultra-low power consumption of 2.5W and bus-powered operation for plug-and-play functionality</p><p>● For dual-port link aggregation, USB4/Thunderbolt device expansion, and industrial-grade wide-temperature operation: The DTB3F22 is the top choice, featuring dual Ethernet ports and daisy-chain functionality for full compatibility with professional scenarios</p><p>No need to open the case or use a PCIe slot—simply plug it into a Thunderbolt port to enjoy the high speed and stability of a 10 Gigabit fiber network. This is the optimal solution for 10 Gigabit upgrades on devices without PCIe slots.</p><p><br/></p>
