Established in 2012 in Hong Kong as a hi-tech communication enterprise.
Kocent Optec Limited has emerged as one of China's leading fiber optic termination product manufacturers and solution providers. We are dedicated to developing and manufacturing fiber optic communication products ranging from passive to active categories for telecommunication networks, enterprise networks, and modern data centers.
By leveraging our extensive experience and excellent production capacity gained over the years, we magnify the outcome for our valuable customers, expanding their core competencies and helping them outperform competitors in the high-speed data market.
The global demand for 40G QSFP+ Direct Attach Copper (DAC) cables has surged as data centers transition from 10G to 40G and 100G architectures. Industrial automation and IoT hubs require low-latency connections that only Twinax copper can provide over short distances. As a leading OEM 40G DAC Cable Manufacturer, we see a massive shift towards high-density rack cabling where cost-efficiency and power consumption are critical.
Artificial Intelligence (AI) training clusters and Big Data analytics platforms require massive bandwidth. 40G DAC cables serve as the backbone for Intra-rack connections, linking Top-of-Rack (ToR) switches to servers. The "Zero Power Consumption" nature of passive DAC cables makes them the preferred choice for green data centers looking to reduce their carbon footprint while maintaining 40Gbps throughput.
Enterprises in North America, Europe, and Southeast Asia are increasingly looking for reliable Chinese DAC Factories to secure their supply chains. Key procurement requirements include multi-vendor compatibility (Cisco, Arista, Juniper), UL/CE certification, and rapid prototyping for custom lengths. Kocent Optec fulfills these needs by offering "Second-to-None" contract manufacturing services.
Our 40G DAC cables are widely used in 5G base stations, financial trading floors, and high-frequency cloud computing nodes where every microsecond and every watt counts.
KCO Fiber provides SFP, SFP+, QSFP, AOC, and DAC solutions compatible with major brands: Cisco, Huawei, ZTE, H3C, Juniper, HP, TP-link, D-Link, Dell, Netgear, Ruijie, and more. Our EEPROM coding service ensures seamless "plug-and-play" integration.
We provide tailored solutions including optical design, mechanical design, PCB layout, electrical design, and software/firmware design. Whether you need specific cable lengths (0.5m to 7m for passive) or custom labels and logos, we deliver.
Beyond DAC cables, we excel in MTP/MPO Patch Cords, Tactical Fiber for FTTA, CPRI Patch Cords, and High-Density Distribution Frames. Our OEM partnership allows you to leverage our technology to expand your revenue.
Follow strictly fiber optic industry standards by using mature scientific methods to deliver 100% tested products.

As a leading 40G DAC manufacturer in China, we benefit from a robust ecosystem. From high-quality copper shielding to precision-engineered QSFP+ zinc alloy shells, every component is sourced and assembled within a tight geographic area, reducing lead times and costs.
Whether you are a startup needing 10 units or a global enterprise requiring 10,000, our production lines are built for scalability. Our 13 years of experience ensures that mass production never compromises quality or consistency.
Kocent Optec invests heavily in R&D to stay ahead of the curve. While we dominate the 40G DAC market, we are already providing solutions for 100G, 200G, and 400G interconnects to future-proof our clients' infrastructure.
Our commitment to quality is unwavering. Every 40G DAC Cable that leaves our factory undergoes rigorous signal integrity testing, including eye-diagram analysis and bit error rate testing (BERT). We understand that in a data center environment, one faulty cable can lead to significant downtime. That is why 100% of our products are inspected before shipment.
With headquarters in Hong Kong and manufacturing facilities in mainland China, we bridge the gap between high-tech innovation and cost-effective manufacturing. Kocent Optec welcomes customers worldwide to develop long-term OEM/ODM partnerships.
