40G QSFP+ DAC (Direct-attach Cable) cable assembly offers a cost-effective way to establish a 40G link connectivity between devices using QSFP ports. The 40G QSFP+ DAC cable is designed for 40Gb/s high-speed interconnecting networking applications such as data centers and high-performance computing (HPC), storage networking, etc. It is fully compliant with QSFP+ Multi-Source Agreement (MSA) standard SFF-8436 and IEEE 802.3ba 40GBASE-CR4. 40G QSFP+ DAC cable is a cost-effective and lower power consumption alternative to QSFP+ optical transceivers and QSFP+ active optical fiber (QSFP+ AOC). AscentOptics could provide high performance passive 40G QSFP+ DAC cables (ranging from 0.5 meter to 7 meters)and active 40G QSFP+ DAC cables (from 1 meter to 10 meters). It is widely used for short-distance connections and offers a 40G link between QSFP+ ports of switches inside racks and adjacent racks.
