Premium fiber cables, active transceivers, and OLT system distribution units engineered for high-density modern topologies.
Analyzing key paradigm shifts in local server topologies, core transceivers, and cost-effective twinaxial architectures.
For Top-of-Rack (ToR) patching, SFP+ 10G Direct Attach Copper (DAC) cables provide a direct physical connection without active conversion components. This near-zero latency architecture is crucial for high-frequency trading, real-time database transactions, and high-performance computing clusters.
Unlike active optical transceivers, passive DAC cables require virtually zero power (approx. 0.1W per link). Scaled across massive hyperscale data centers, this significantly lowers overall utility draw and heat generation, reducing secondary HVAC system demands and total operational expenses.
By eliminating optical lasers, internal photodiodes, and high-frequency transceiver circuits, DAC cables provide a durable and highly reliable cabling channel at a fraction of the capital expenditure of transceivers paired with optical fiber patches.
| Interconnect Type | Maximum Reach | Typical Power Consumption | Latency (ns) | Ideal Application Scenario |
|---|---|---|---|---|
| Passive DAC 10G SFP+ | Up to 7 meters | < 0.1 Watts | ~0.3 nanoseconds | Within-rack server-to-switch aggregation |
| Active Optical Cable (AOC) | Up to 100 meters | ~0.6 - 1.0 Watts | ~2 nanoseconds | Inter-rack connection in medium data centers |
| 10GBASE-T Copper RJ45 | Up to 30 meters | ~2.0 - 2.5 Watts | ~2.6 microseconds | Legacy enterprise networking upgrades |
| 10GBASE-SR Fiber Transceiver | Up to 300 meters (OM3) | ~1.0 Watts | ~0.1 nanoseconds | Spine-Leaf aggregation & structured cabling |
The global demand for reliable data transmissions requires rigorous assembly precision. As an advanced communication hub based in Hong Kong and Shenzhen, China’s industrial ecosystem powers our high-capacity production lines with extreme accuracy.
By optimizing automated production processes, we match customized EEPROM firmware configurations with top-tier network hardware (Cisco, Juniper, Arista, Dell, and others) right at the manufacturing line.
How telecom buyers and datacenter engineers address capacity expansion, compatibility challenges, and supply chain continuity.
One of the biggest concerns for enterprise IT teams is manufacturer compatibility lock-in. A single patch link might connect a Cisco switch to a Dell server, requiring the cable's EEPROM firmware to satisfy both ends. Kocent Optec solves this issue by offering custom EEPROM configuration options, ensuring seamless performance across diverse multi-vendor setups.
Large-scale networks require reliable, on-time deliveries. Relying on single-source local distributors often leads to project bottlenecks during supply shortages. Partnering directly with Kocent Optec ensures stable factory pricing and consistent production capacity, bypassing third-party supply constraints.
Unlike standard patch cables, DAC cables must maintain signal integrity under tight bend radiuses within packed server racks. Our cables are built with highly flexible jackets, secure latch mechanisms, and robust strain reliefs to ensure reliable, long-term performance.

By leveraging our deep industry experience and production capacity, we help our global partners build stronger, more reliable network systems. We focus on close collaboration and long-term partnerships, matching our production and customization capabilities to our clients' precise project requirements.
With over 13 years of manufacturing expertise, we strictly follow international quality standards. Using proven scientific testing, we ensure that 100% of our products undergo thorough inspection and verification before leaving our facility.
High-speed interconnect products optimized for modern IT architectures, edge environments, and enterprise grids.
Ideal for connecting high-speed servers directly to rack-mount aggregation switches. Our SFP+ 10G DAC assemblies offer a reliable, cost-effective link under 7 meters, eliminating the need for expensive transceivers and delicate patch cords.
Perfect for linking high-capacity network storage networks (NAS and SAN) with processing units. Passive copper links deliver stable, high-throughput connections with minimal power requirements and maximum data integrity.
As edge locations expand, simple, low-power interconnect solutions are essential. Passive DAC systems run cooler in compact, unconditioned spaces compared to optical alternatives, ensuring long-term reliability in the field.
Answering key technical questions regarding compatibility, mechanical design, and performance optimizations.
Passive DAC cables contain no signal amplification components. They rely on the host equipment's switch port to handle equalization and signal boosting. Because of this, passive models are limited to short runs (typically up to 7 meters). Active DAC cables include small built-in signal processing chips within the connector housing, extending transmission distance to about 10-15 meters over copper.
We maintain a comprehensive library of vendor firmware. Each high-speed cable or module's EEPROM is programmed and tested with target hardware profiles (such as Cisco, Arista, Juniper, HP, or Dell) prior to packaging. This ensures the host system recognizes the transceiver or cable without throwing compatibility warnings.
We typically use 30 AWG copper wire for short lengths (up to 3 meters) to keep cables flexible and easy to manage in tight layouts. For longer runs (5 to 7 meters), we use thicker 24 AWG or 26 AWG wire to minimize signal attenuation and maintain structural integrity across the longer link.
In data centers with thousands of active links, a transceiver drawing 1-2 Watts per port quickly adds up to significant power demands. High-density setups also require extra cooling to keep equipment within safe operating temperatures. Passive DAC cables, drawing only about 0.1 Watt per link, drastically lower both direct utility costs and system-wide thermal management requirements.
Yes, we provide full OEM and ODM services. We customize cable lengths, jacket choices (PVC, LSZH, Plenum), labeling, packaging, and EEPROM profiles to meet the exact specifications of telecommunication projects and enterprise systems.
