High-reliability active and passive network components designed for high-density telecommunication infrastructure.
Established in 2012 in Hong Kong as a hi-tech communication enterprise, Kocent Optec Limited has emerged as one of China's premier fiber optic termination product manufacturers and system solution providers.
We dedicate ourselves entirely to developing, designing, and manufacturing state-of-the-art fiber optic and high-speed copper communication assemblies. Our solutions scale from passive to active categories, servicing global telecommunications networks, hybrid enterprise clouds, and hyperscale data centers.
By leveraging our extensive production capacity and mature scientific methodologies gained over the years, we maximize output quality, help our global customers outperform competitors, and expand their capabilities in next-gen infrastructure deployment.
Analyzing why Direct Attach Copper (DAC) remains the undisputed economic standard for short-range interconnects.
In modern hyperscale cloud computing, data centers require high-speed pathways that connect servers to Top-of-Rack (ToR) switches. 10G Twinax Copper Cables, also known as SFP+ Direct Attach Copper (DAC) cables, represent the most efficient and robust solution for short-distance connections (typically up to 7-10 meters).
Unlike active optical transceivers, passive Twinax cables do not consume power at the transceiver module end. Latency is virtually eliminated because there is no optical-to-electrical signal conversion. This latency reduction (microsecond level) is essential for financial trading systems, distributed database synchronization, and HPC (High-Performance Computing) clusters.
From an operating cost perspective, switching from fiber transceivers to 10G Twinax cables in server rack configurations saves significant power. Across tens of thousands of connections, this reduction in heat generation minimizes HVAC cooling loads, directly aligning with green data center energy-efficiency initiatives.

| Feature Parameter | Passive 10G SFP+ Twinax Cable | Active 10G SFP+ Twinax Cable | Active Optical Cable (AOC) |
|---|---|---|---|
| Transmission Distance | 0.5m to 7m (Depending on AWG rating) | 7m to 15m (Integrated booster chip) | 1m up to 100m+ (via Multi-mode Fiber) |
| Power Consumption | < 0.1 Watts (Virtually zero) | < 0.5 Watts to 1 Watt | Typically 1.0 - 1.5 Watts per end |
| Signal Latency | Ultra-Low (Direct copper conduction) | Low (Negligible booster delay) | High relative to copper (O-E-O conversion) |
| Electromagnetic Shielding | Requires robust foil and braiding (EMI sensitive) | Integrated active EMI filtering | Immune to EMI (Optic core) |
| Cost Profile (TCO) | Lowest Capital & Operational Expenses | Moderate capital expense | Higher capital expense |
| Bending Radius | Rigid (Determined by AWG thickness) | Rigid but adaptable | Highly flexible (Thin optical fiber) |
How physical layer engineering adapts to support rapid shifts from 10G to 400G and 800G connectivity.
Our 10G SFP+ Twinax cables are manufactured using premium copper wire. Available in gauges from 30AWG to 24AWG, they minimize insertion loss and mitigate NEXT/FEXT crosstalk at 10.3125 Gbps transmission frequencies.
We bypass proprietary system limitations using EEPROM custom programming. Kocent Optec assemblies are compatible with mainstream platforms, including Cisco, Juniper, Arista, HP, Dell, and Brocade.
We leverage architectural lessons from our 10G Twinax designs to scale production. This technology transitions toward 25G SFP28, 40G QSFP+, 100G QSFP28, and PAM4 modulated 400G/800G copper interconnects.
Kocent Optec Limited places immense emphasis on partner collaboration. We act as a valuable partner in developing high-speed connectivity solutions rather than just an OEM supplier. Our 10G SFP+ Twinax cables are tested using state-of-the-art vector network analyzers (VNA).
We run bit-error rate testing (BERT) over simulated environmental chambers to verify signal stability. This testing ensures insertion loss, return loss, and NEXT levels meet or exceed SFF-8431, SFF-8432, and IEEE 802.3ae specifications.
With more than 13 years of experience in manufacturing, we deliver products on time and ensure 100% of our units are tested and inspected before shipment, preventing downtime in production networks.
Providing high-compliance connectivity products for the world's most demanding carrier infrastructures.
Ensuring cross-border certification and strict flammability standards for international deployments.
Fully compliant with restriction of hazardous substances directives for environmental safety.
Available in LSZH (Low Smoke Zero Halogen) and PVC outer sheaths to meet fire safety codes.
Certified electromagnetic compatibility (EMC) preventing RF interference in high-density areas.
Engineered to comply with SFF-8431 and SFF-8432 specifications for physical dimensions.
In-depth responses to common inquiries from infrastructure engineers and procurement managers.
Premium processing accessories, cleaning tools, and fiber patch cables supporting international telecommunication standards.
