Why twinaxial copper cabling remains the gold standard for ultra-low latency, short-range high-speed data center interconnects (DCI).
Unlike optical transceivers which require electro-optical conversion, passive SFP+ DAC cables route the electrical signal directly through twinaxial copper conductors. This achieves near-zero latency, critical for high-frequency trading (HFT) and real-time computing clusters.
Passive 10G DAC cables consume virtually zero power (<0.1W per port), whereas optical modules require 1W to 1.5W per interface. Across thousands of server racks, integrating copper DACs significantly reduces PUE (Power Usage Effectiveness) and HVAC cooling overheads.
Constructed with dual-shielded twinaxial cable, our 10G SFP+ DACs eliminate electromagnetic interference (EMI) and minimize near-end crosstalk (NEXT). The solid copper core provides structural rigidity and stable differential impedance of 100 ohms.
When selecting 10G SFP+ Direct Attach Cables, network architects must balance distance requirements with cable thickness (AWG - American Wire Gauge). For short distances (0.5m to 3m), Passive DACs are highly recommended as they lack active signal-restoring chips, making them both highly reliable and cost-effective. However, as link length extends to 5m-7m, signal attenuation increases, requiring either thicker copper (e.g., 24 AWG instead of 30 AWG) or the inclusion of an active linear equalizer inside the transceiver shell (Active DACs).
| Cable Length (m) | Standard AWG | Type | Signal Attenuation (10G) | Typical Application |
|---|---|---|---|---|
| 0.5m - 1.5m | 30 AWG | Passive | Low (< 5 dB) | Intra-rack, Server-to-ToR Switch |
| 2m - 3m | 30 / 28 AWG | Passive | Moderate (< 10 dB) | Adjacent rack connection |
| 5m | 26 / 24 AWG | Passive / Active | High (Needs signal boost) | End-of-Row (EoR) Switch linking |
| 7m - 10m | 24 AWG | Active | Critical (Active compensation) | Inter-cabinet distribution |
Our manufacturing base leverages state-of-the-art automation systems to execute high-density soldering, automatic cable stripping, and precise component assembly. By transitioning to a data-driven Factory 4.0 infrastructure, we guarantee consistency in differential signal performance, minimizing variation across large-scale production batches.
Our supply chain model ensures continuous access to high-grade raw materials (including premium shieldings, custom PCBAs, and copper conductors), insulating our production capacity from regional disruption. This level of supply control translates to stable lead times and highly competitive wholesale pricing matrices for global operators.
Ensuring jitter-free performance and clean eye height margins.
Full interoperability with standard SFF-8431 and SFF-8432 specifications.
Tailored interconnect frameworks designed for specialized enterprise verticals and high-bandwidth topologies.
Simplifying Top-of-Rack (ToR) switch links. By utilizing 10G SFP+ DAC copper cables, operators can link host bus adapters (HBAs) to aggregation panels within the same rack frame, drastically lowering capital and power expenditures.
In algorithmic financial environments, a few nanoseconds determine profitability. DAC Twinaxial cables present zero latency during transmission compared to transceiver delay, giving institutions a tangible trading edge.
Facilitating multi-gigabit connections between SAS controllers, NAS systems, and server mainframes. Enables fast backup schedules, replication schemes, and failover clustering without latency-induced bottlenecks.
Ensuring your cable infrastructure scales seamlessly from legacy 10G frameworks to high-density 400G and 800G fabrics.
As networks undergo continuous transitions from 10G SFP+ to 25G SFP28, 40G/100G QSFP28, and PAM4-modulated 400G/800G layouts, selecting physical infrastructure that minimizes replacement intervals is paramount. While copper remains the cost-optimal choice for short distances, we maintain a complete technological pipeline that covers copper and active optical configurations (AOC) up to 400G/800G PAM4 technologies. This enables network managers to secure a single trusted provider for both legacy distribution and next-generation greenfield expansions.
