Industry-leading components for global telecommunication infrastructure
In the rapidly evolving landscape of data center architecture, the Direct Attach Copper (DAC) SFP28 cable has emerged as the gold standard for short-range, high-speed interconnectivity. As the world transitions from traditional 10G networks to more robust 25G and 100G frameworks, the demand for cost-effective, low-latency, and low-power consumption solutions has skyrocketed.
Experience & Expertise: With over 13 years in the industry, Kocent Optec Limited understands that 25G SFP28 DAC cables are not just passive components; they are the lifelines of modern high-frequency trading platforms, AI training clusters, and massive cloud storage facilities. Our DAC solutions leverage SFP28 (Small Form-factor Pluggable 28) technology to provide a single-channel 25Gbps rate, perfectly aligning with the IEEE 802.3by and SFF-8402 standards.
Stay ahead with the latest shifts in global networking infrastructure
Enterprises are increasingly moving from 10G to 25G as the primary server-to-switch connection, offering 2.5x the bandwidth with minimal infrastructure changes.
The explosion of AI requires massive GPU clusters. DAC SFP28 cables provide the ultra-low latency necessary for synchronized data processing in AI nodes.
As processing moves closer to the user (5G/IoT), SFP28 DAC cables offer a reliable, rugged solution for decentralized micro-data centers.
For links under 5 meters, DAC cables are significantly cheaper than using two transceivers and a fiber patch cord. Wholesale buyers save up to 60% on interconnect costs.
Passive DACs consume nearly zero power. In a data center with thousands of ports, this translates to massive savings in cooling and electricity bills.
Without optical lasers, the MTBF (Mean Time Between Failures) of DAC cables is vastly superior to active optical solutions, ensuring 24/7 uptime.
Unmatched value, rapid scalability, and technical precision
Located in the heart of the global electronics hub, we control the entire supply chain from raw copper and PCB layout to final assembly and testing.
Our DAC SFP28 cables are EEPROM-coded to be 100% compatible with Cisco, Arista, Juniper, Dell, Mellanox, and over 50 other major switch vendors.
Every batch undergoes signal integrity tests, BER (Bit Error Rate) analysis, and real-switch environment verification before shipment.
