Founded in 2012, Kocent Optec Limited has grown into a world-class high-tech communication enterprise. Headquartered in Hong Kong, we serve as one of China's most trusted manufacturers and custom solution providers for active and passive fiber optic termination products. Over the last decade, our footprint has expanded globally as we cater to the demanding criteria of hyperscale data centers, tier-1 telecommunication operators, and massive enterprise networks.
Our operational philosophy is built around technological synergy. We do not just build modules; we develop system-wide integration platforms. Our expertise ranges from passive fiber path elements (attenuators, splitters, loopbacks) to top-tier high-speed active components, including state-of-the-art QSFP+, QSFP28, and next-generation QSFP-DD modules optimized for active optical networks.
"By leveraging our extensive experience and excellent production capacity we gained over the years, we magnify the outcome for our valuable customers, which ultimately expands their core competencies and helps them outperform competitors."
Analyzing why high-density optical engines surpass traditional copper alternatives in current cloud and cloud-edge clusters.
Our AOC lines utilize high-performance vertical-cavity surface-emitting lasers (VCSEL) coupled with advanced PIN receiver arrays. This integration produces lower latency and drastically reduces Power Dissipation to under 2.5W per end on 100G configurations.
By using OM3/OM4/OM5 multimode fibers instead of heavy copper conductors, our AOCs are completely immune to electromagnetic interference (EMI). They minimize cable congestion in modern tight racks, improving airflow and lowering overall cooling bills.
We supply unique ODM firmware variants, enabling compatibility with Cisco, Juniper, Arista, Mellanox, Dell, HP, and Huawei environments. Your equipment reads the AOC natively, preventing warning messages and configuration faults.
| Specification Parameter | Direct Attach Copper (DAC) | Active Optical Cable (AOC) | Discrete Optical Modules + Fiber Patch |
|---|---|---|---|
| Transmission Distance | 0.5m - 7m (short-range) | 1m - 100m (OM3/OM4/OM5) | Up to 10km (LR4) / 40km (ER4) |
| Power Consumption | Ultra-low (~0.1W) | Moderate (1.5W - 3.5W per end) | High (3.5W - 5.5W per transceiver) |
| Bending Radius & Flexing | Thick, heavy, hard to route | Flexible, thin optical fiber cores | Highly flexible but delicate interfaces |
| Interference Profile | Susceptible to EMI/RFI | 100% Electromagnetically Immune | 100% Electromagnetically Immune |
| Operational Cost (TCO) | Low setup cost | Optimal performance/cost ratio | Highest capital and module cost |
The rise of Generative AI (LLMs), deep learning clusters, and high-performance computing (HPC) has altered global fiber infrastructure requirements. Traditional 10G and 25G routes are migrating to 100G QSFP28, 200G QSFP56, and 400G/800G QSFP-DD paths.
In this high-performance climate, latency and packet drop rates are key performance indicators. We design our custom AOC QSFP assemblies to handle PAM4 signaling and NRZ encoding with minimal Bit Error Rates (BER), surpassing standard IEEE metrics. This helps hyperscale operators process workloads reliably across dense computing clusters.
Our ODM model supports custom length designations, unique pulling-eye modifications, and color-coded jacket designs (OM3 Aqua, OM4 Erika Violet, OM5 Lime Green) to streamline layout management in cleanrooms.
Operating a modernized manufacturing complex in Shenzhen allows Kocent Optec to source premium raw optoelectronic materials efficiently. This localized base helps mitigate standard supply chain bottlenecks, giving our customers predictable lead times and shielding them from global logistics volatility.
We work closely with semiconductor, component, and silicon photonics packaging companies to ensure our ODM active cables scale quickly during high-volume deployments. Our automated manufacturing line integrates precision fiber alignment tools, high-speed optical spectrum analyzers, and temperature-controlled testing ovens.
"With more than 13 years of experience in manufacturing telecommunication fiber optic products, we follow strictly fiber optic industry standards by using mature scientific methods to deliver your products on time and ensure that 100% products are tested and inspected before shipment."
How global enterprises deploy KCO AOC technologies to solve complex regional networking issues.
In massive multi-tier colocation facilities, our customized 100G QSFP28 to 4x 25G SFP28 breakout AOCs are used to run Top-of-Rack (ToR) switch links directly down to server NICs. This approach improves cabling density and eases thermal loads in dense server arrays.
European operators prioritize carbon neutrality and strict power limits. Kocent Optec's active cables are designed for low power consumption, saving up to 1.2 Watts per port compared to transceiver setups, helping operators hit PUE targets.
AP telecom carriers use our rugged, customized optical solutions to support OTN and 5G midhaul infrastructure. These modules handle outdoor environments and temperature shifts, keeping cell site networks running smoothly.
As networks scale, speed requirements continue to climb. At Kocent Optec, we are developing next-generation active optical interconnects to match these bandwidth demands.
Our engineering pipeline includes Co-Packaged Optics (CPO) and Silicon Photonics (SiPh) platforms designed to scale beyond the 800G threshold into 1.6T environments. By integrating lasers directly with ASIC chipsets, we aim to lower power consumption, reduce thermal loads, and decrease latency for tomorrow's large-scale computing tasks.
At the same time, we continue to optimize our core 40G QSFP+ and 100G QSFP28 designs, ensuring our current product lineup remains highly reliable and cost-effective for enterprise networks worldwide.
To operate reliably in international markets, our products meet a broad array of regulatory and performance standards. Every component complies with strict regional guidelines, ensuring safety, quality, and environmental responsibility.
Our manufacturing and assembly processes strictly align with RoHS, CE, FCC, and Reach directives. Our optical cables are tested to Telcordia GR-468-CORE specifications to ensure reliable service under varying thermal and mechanical conditions. By maintaining these high standards, we help our clients navigate local customs and local network compliance requirements smoothly.
Our custom OEM/ODM solutions are trusted by leading tier-1 and tier-2 telecommunication operators worldwide, meeting their strict compliance standards:
