Established in 2012 in Hong Kong as a high-tech communication enterprise, Kocent Optec Limited has emerged as one of China's premier fiber optic termination and high-speed cabling manufacturers and turnkey solution providers.
We are comprehensively dedicated to developing and manufacturing highly reliable, high-performance optical communication products and copper interconnect systems. Our product portfolios range across both passive and active transmission categories, engineered specifically for global telecommunication networks, enterprise infrastructures, and massive hyperscale data centers.
As enterprise storage requirements, distributed cloud networks, and localized artificial intelligence applications expand, data center architectures are undergoing structural transformations. High-density networks require economical, thermal-efficient, and low-latency physical link channels. While multi-mode optical transceivers are suitable for longer distances, the 10G SFP+ Direct Attach Copper (DAC) remains the unmatched backbone for short-range intra-rack top-of-rack (ToR) switch-to-server connections.
By bypassing the optical-to-electrical conversions required by transceivers, passive DAC cables minimize power consumption to near zero (approximately 0.1W per link), substantially dropping data center PUE metrics.
Because there is no transceiver serialization/deserialization latency, passive DACs deliver physical layer latency of less than 15 nanoseconds, making them highly suited for high-frequency trading (HFT) and complex industrial automated processing.
Sourcing direct from an optimized 10G DAC factory reduces hardware CAPEX by up to 60% compared to optical module deployment. Reliability increases as active failure nodes drop to zero.
Our competitive advantage rests on strict manufacturing methodology. Every passive DAC twinax cable is constructed with high-grade, shielded twin-axial copper conductors (ranging from 30AWG down to 24AWG depending on target link lengths up to 7 meters). This ensures minimal signal insertion loss and zero crosstalk at 10.3125 Gbps frequencies.
Quality assurance is embedded in each manufacturing phase:
Modern telecommunication networks and cloud hubs are built using equipment from different network hardware vendors. Operating in this environment requires high levels of flexibility. We specialize in cross-compatibility programming. We supply dual-coded DAC cables capable of connecting a Cisco switch at one end to a Juniper or HP server interface on the other, eliminating the premium cost of proprietary hardware locks.
We analyze SFF-8431, SFF-8432, and SFF-8472 specifications in detail. This ensures that every passive direct attach copper twinax assembly matches the hardware interfaces perfectly. This reduces the error rates that often occur in mixed-brand data center environments.
Through our customized multi-vendor compatibility solutions, telecom operators can implement open hardware architectures, lowering their global procurement overheads without sacrificing link integrity or network uptime.
By leveraging our extensive experience and production capacity, we improve outcomes for our customers, helping them outperform their competitors. We emphasize customer collaboration, defining ourselves as your reliable partner in fiber optic and copper connection solutions. We believe our technical differentiators are your core advantages.
Today, our OEM and ODM products support major telecommunications infrastructure projects worldwide. Our terminal operators and partners include: SingTel, Vodafone, America Movil, Telefonica, Bharti Airtel, Orange, Telenor, VimpelCom, TeliaSonera, Saudi Telecom, MTN, Viettel, Bitel, VNPT, Laos Telecom, MYTEL, Telkom, Telekom, Entel, FiberTel, StarFiber, Ooredoo, Beeline, Azercell, and others.
We strictly follow international environmental and safety standards. All DAC products carry RoHS, CE, FCC, and REACH compliance certifications, meeting the requirements of European, American, and Asian markets.
As 10G networks continue to run core infrastructure for smaller enterprises and Edge environments, hyperscale data centers are moving towards 100G, 400G, and 800G link layers. Our factory R&D team remains at the forefront of this evolution, constantly updating our manufacturing processes for next-generation copper and optical transceiver designs.
Providing cost-effective 25G SFP28 passive copper cables utilizing improved AWG materials to preserve signal-integrity over longer spans.
Optimized assembly lines for PAM4 modulation, manufacturing direct-attach copper and optical transceivers for mid-tier data centers.
Developing Active Copper Cables (ACC) featuring linear equalization chips to extend copper range parameters at higher bandwidths.
10G DAC cables offer a low-cost, low-power alternative to optical modules. Since they do not have active laser components, their average power consumption is around 0.1W, which helps reduce thermal load in racks. Additionally, passive DACs eliminate the optical-to-electrical latency overhead, providing high-speed, direct copper paths for intra-rack setups.
Every cable is programmed with customized vendor code in our testing lab before shipping. Our EEPROM database is regularly updated to stay compatible with firmware changes from brands like Cisco, Arista, Juniper, HP, and Dell, ensuring our cables connect seamlessly to your existing network.
AWG (American Wire Gauge) indicates the thickness of the copper conductors inside the cable. A lower AWG number means a thicker conductor. Thicker wires (like 24AWG) experience less signal attenuation over distance and are used for lengths up to 7 meters. Thinner wires (like 30AWG) are more flexible and are ideal for short runs under 2 meters, helping with airflow in tight spaces.
Yes, all products manufactured by Kocent Optec comply with international regulatory frameworks including CE, FCC, RoHS, and REACH. This ensures environmental safety, non-toxicity, and compliance with regional operator requirements.
