Pre-configured high-performance DAC and AOC assemblies designed to meet the strict demands of São Paulo and Fortaleza Cloud Nodes.
Brazil represents the largest digital infrastructure ecosystem in Latin America, capturing over 40% of the regional hyperscale data center footprint. Driven by rapid transformations in financial tech (such as the PIX instant payment system), the country's optical and copper transport networks require unmatched bandwidth density, extreme reliability, and thermal robustness.
In hyper-dense configurations typical of metropolitan centers like São Paulo (Campinas, Barueri), Rio de Janeiro, and Fortaleza, passive copper technology (Direct Attach Copper - DAC) and active fiber technology (Active Optical Cable - AOC) form the primary backbone for Top-of-Rack (ToR) and Leaf-Spine architectures.
Data centers in equatorial regions such as Fortaleza require precise planning for environmental thermal regulation. Selecting the proper energy profile between Active Optical Cables (AOC) and Passive Direct Attach Cables (DAC) directly impacts overall PUE (Power Usage Effectiveness) metrics.
A side-by-side technical evaluation for Brazil's engineering leaders managing high-density server environments.
| Feature Parameter | Direct Attach Copper (DAC) | Active Optical Cable (AOC) | Brazilian Operational Context |
|---|---|---|---|
| Transmission Distance | Up to 5m (Passive 10G/25G/100G) | Up to 100m (over OM3/OM4 Multimode) | DAC is perfect for intra-rack patching; AOC is required for larger rows and multi-row connections. |
| Power Consumption | Extremely Low (~0.1W per port) | Higher (~1.5W - 3W per end) | Using DAC for high-volume ToR links significantly lowers active cooling requirements and operational costs (OPEX). |
| EMI Immunity | Susceptible to electromagnetic interference | 100% EMI Immune (Fiber optic medium) | Highly recommended for industrial data rooms adjacent to heavy electrical infrastructure. |
| Cable Weight & Diameter | Heavy, rigid, thicker gauge (e.g. 30AWG to 26AWG) | Lightweight, thin, flexible profile | AOC facilitates optimal airflow inside crowded vertical cable organizers where space is limited. |
| Bending Radius | High (requires structured path planning) | Tight (easy management in high-density racks) | Protects structural health of interconnect pathways inside legacy cabinets. |
As global supply lines continue to experience shipping congestion and chip allocation shortages, Kocent Optec Limited guarantees consistent delivery times. By integrating advanced production scheduling with fully automated robotic termination, we bypass the conventional bottlenecks that delay large-scale enterprise deployments.
Every single DAC and AOC unit undergoes strict environmental and hardware interoperability testing on Cisco, Arista, Juniper, and Huawei switches before shipment.
We write customized vendor firmware directly to the transceivers' memory block, allowing perfect vendor compatibility without generic system errors.
Understanding the transition from 25G NRZ to PAM4-based high-speed transmission standards.
Data center upgrades in Brazilian financial hubs are transitioning to 100G and 400G configurations. While NRZ (Non-Return-to-Zero) technology served legacy 10G/25G architectures well, the deployment of 400G (using 8x50G lanes) and the future migration toward 800G require PAM4 (Pulse Amplitude Modulation 4-Level) standards.
This evolution increases the need for high-quality copper shielding and advanced signal restoration circuitry inside transceivers. Kocent Optec is at the forefront of this evolution, designing low-power active optical components that optimize signals in dense, high-frequency operations.
Importing high-speed telecom products into Brazil requires navigating local custom systems like SISCOMEX, combined with specific tax assessments (such as ICMS, IPI, and PIS/COFINS). At Kocent Optec, we support our commercial partners by ensuring all technical documentation meets the requirements for ANATEL compliance.
Our raw materials comply with international safety directives (RoHS, CE, UL). We construct our cable jackets using Low Smoke Zero Halogen (LSZH) and Plenum-rated compounds to meet local fire protection and building safety standards.
