Unlocking physical layer cost-efficiency, ultra-low latency, and compatibility compliance for hyper-scale network integrations.
In the architecture of modern enterprise server rooms, hyper-scale cloud data centers, and telecommunication distribution networks, the physical layer represents both a performance bottleneck and a core cost driver. As digital networks scale toward edge computing and high-density virtualization, the demand for 10G SFP+ Direct Attach Copper (DAC) Cables remains a cornerstone of short-range interconnect strategies. Offering a zero-latency, highly energy-efficient alternative to optical transceivers, DAC twinaxial cables are essential for Top-of-Rack (ToR) switch-to-server connection topologies.
As a leading hi-tech communications enterprise, Kocent Optec Limited (established in 2012 in Hongkong) acts as a pivotal ODM/OEM partner to design, code, and manufacture industry-standard 10G SFP+ DAC twinax solutions. We address the critical pain points of telecommunication engineering: absolute multi-vendor compatibility, electromagnetic shielding integrity, structural durability, and physical optimization. Through our advanced assembly line and rigid 100% component validation, we offer global procurement teams custom quotes and technical architectures designed to secure a long-term network lifespan.
Decentralized supply chains, cost scaling, and strict verification protocols drive procurement demand.
Procurement leads must bypass vendor-lock models. Our ODM solutions customize EEPROM registers dynamically to match specific manufacturer keys (e.g., Cisco, Arista, Juniper, Dell, HPE), ensuring zero-error port authentication.
Data centers choose wire gauge based on distance and bend radius. We engineer assemblies across a spectrum from 30AWG (thin, highly flexible for short hops) to 24AWG (thicker, lower attenuation for maximum distances).
Deploying 10GBASE-T copper transceivers or SFP+ optical units consumes up to 1.5W-3W per port. Passive DAC twinax runs under 0.1W, which results in significant multi-million dollar savings in annual power and HVAC cooling overheads.
Kocent Optec Limited leverages extensive design experience and manufacturing capabilities to support our partners. As a leading manufacturer based in China, we control the production cycle from raw twinaxial shielding structure formulation to localized EEPROM programming.
By focusing on physical design criteria, we maintain stable impedance matching at exactly 100 ohms, keeping return loss to a minimum. Our active quality control ensures each cable meets strict environmental, mechanical, and signal integrity requirements, giving you an advantage over competitors.

With more than 13 years of experience in manufacturing telecommunication fiber optic and copper products, we follow strictly fiber optic and copper networking industry standards. We use mature scientific methods to deliver your products on time and ensure that 100% of products are tested and inspected before shipment.
Our verification suite includes eye-diagram analysis, physical bend testing, insertion loss mapping, and high-frequency network simulations. Every single batch of 10G SFP+ DAC Cables is subjected to diagnostic tests on native switches to confirm cross-platform compatibility.
Why hybrid networks rely on a combination of high-speed copper DAC and high-density fiber routing.
Modern data networks are rarely built on a single transmission medium. While fiber optic adaptors, couplers, and transceivers handle long-distance backbone distribution and inter-building links, copper direct-attach cables dominate short-range switch-to-server distribution. Below is an overview of how we align our custom ODM capabilities to serve these network architectures:
Passive 10G SFP+ DAC cables are the ideal choice for connections under 7 meters. They allow switches to connect to servers in the same rack with low power draw, low cost, and minimal latency.
For connections exceeding 10 meters, we integrate MPO/MTP patch panels and fiber adapters to support high-density backbone routing. This lets you transition smoothly from local copper runs to optical distribution.
Our ODM and OEM designs are engineered to satisfy the demands of telecommunication tenders, providing stable physical layer connections and consistent data performance over years of continuous operation.
Our emphasis on customer collaboration helps our partners grow their core competencies. Many of our OEM and ODM products have won telecom operator tenders and satisfy strict end-user requests worldwide.
Today, Kocent Optec Limited serves key telecom operators and enterprises across East Asia, Southeast Asia, the Middle East, Europe, South America, North America, and Africa. We focus on providing high-quality, reliable connectivity products that help keep operators connected around the world.
Future-proofing physical infrastructures for emerging AI workloads and high-throughput environments.
As enterprise storage arrays and database systems handle growing amounts of data, the underlying network infrastructure must evolve to keep pace. While 10G SFP+ DAC cables remain a highly popular and cost-effective interconnect choice, data centers are actively mapping their pathways toward higher speeds. Our ODM service is structured to support this transition seamlessly:
The current standard for short-range server connections. Highly cost-effective and energy-efficient for gigabit-to-10-gigabit network upgrades.
Using single-lane 25Gbps signaling, SFP28 is becoming the preferred choice for newer server nodes, utilizing similar MSA footprints as 10G SFP+.
Utilizes four 25Gbps lanes. This configuration is widely deployed in high-density switch interconnects and core data routing centers.
Designed for the next generation of AI workloads, cloud platforms, and large-scale optical backbones using PAM4 modulation.
