Product Specifications

The 40Gbps QSFP+ Direct Attach Passive Copper Cable (CT-40G-QDAC-XX) is a high-performance, cost-effective solution for short-range communication in high-speed networking applications. Supporting aggregate data rates of up to 40Gbps across four lanes (10Gbps per lane), this cable assembly is ideal for applications such as 10G and 40G Ethernet, InfiniBand (SDR, DDR, QDR), Fiber Channel over Ethernet (FCoE), and SAS interconnects. The cable supports link lengths of up to 5 meters and features a QSFP+ 38-pin connector, compliant with SFF-8436, QSFP+ MSA, and IEEE 802.3ba standards, ensuring compatibility with modern networking hardware.

The cable assembly operates with a power dissipation of just 0.02W and within a commercial temperature range of 0°C to 70°C, offering energy-efficient performance. Designed with a two-wire serial interface for EEPROM signature customization, it provides advanced diagnostic capabilities. This RoHS-compliant cable is well-suited for high-density, low-power interconnects in data centers, enterprise networking environments, and storage area networks, making it a versatile choice for modern communication infrastructure.
