BlueOptics Compatible Centec CAB-Q-Q-3M-CT BlueLAN QSFP+ Direct Attach Copper Cable, 40GBASE-CR4, 30AWG, 3m (CAB-Q-Q-3M-CT-BL)

The BlueOptics CAB-Q-Q-3M-CT-BL is a high-performance, passive QSFP+ Direct Attach Copper (DAC) cable designed to provide reliable 40 Gigabit Ethernet connectivity for data centers and high-performance computing environments. This cable is fully compatible with Centec CAB-Q-Q-3M-CT equipment, ensuring seamless integration into existing network infrastructures. With a length of 3 meters and 30 AWG construction, it offers a cost-effective, low-power solution for short-range interconnects.

Advantages

This DAC cable eliminates the need for separate transceivers and fiber optic cabling, reducing overall system cost and complexity. Its passive design ensures near-zero power consumption, while the twinax copper construction provides excellent signal integrity and low latency. The hot-swappable QSFP+ connectors allow for easy installation and maintenance without network downtime.
