40G QDR QSFP+ Cable

Industrial-Grade 40G QSFP+ DAC Cables – Cost-Effective 40GbE Interconnect Solutions

Our 40G QSFP+ Direct Attach Copper (DAC) cables are engineered to provide high-bandwidth, low-latency connectivity for 40 Gigabit Ethernet and InfiniBand QDR applications. As a specialized B2B manufacturer, we offer these cables as a robust and energy-efficient alternative to optical transceivers for short-distance links (up to 7 meters) in Top-of-Rack (ToR) and switch-to-server configurations.

Key Manufacturing Features:

• Optimized Signal Integrity: Constructed with high-quality shielded twinax copper, our cables ensure minimal EMI (Electromagnetic Interference) and stable 40Gbps aggregate throughput across four lanes.

• Low Latency & Power: The passive copper design ensures near-zero latency and requires no power, significantly reducing the thermal load and operational costs of high-density racks.

• Rigorous Testing: Every assembly is 100% factory-tested for signal integrity and mechanical durability, ensuring 24/7 reliability in enterprise and telecom environments.

OEM/ODM & Private-Label Customization:

We help B2B partners and system integrators build their brand equity through comprehensive customization options:

• Tailored Configurations: Choose from custom lengths, wire gauges (24AWG to 30AWG), and specialized pull-tab colors.

• Hybrid & Breakout Options: We offer QSFP+ to 4x SFP+ breakout cables for connecting 40G ports to 10G equipment.

• Branding & Compatibility: Full private labeling (custom logos, tags, and packaging) and custom EEPROM coding for seamless compatibility major hardware providers.
