Huawei QSFP - 40G - CU3M Compatible 3m 40G QSFP+ Passive DAC Cable
The QSFP-40G-DAC-PxM direct attach copper cable assembly (also known as DAC) is suitable for very short distances and offers a highly cost-effective way to establish a 40 Gigabit link connectivity between devices using QSFP ports. The QSFP+ DAC cable is designed for 40Gb/s high-speed interconnecting networking applications such as high-performance computing (HPC), enterprise networking including top-of-rack switching and network storage markets. It fully complies with QSFP+ Multi-Source Agreement (MSA) standards SFF-8436 and IEEE 802.3ba 40GBASE-CR4. Optcore’s high-quality QSFP+ DAC copper cable provides a cost-effective replacement to QSFP+ transceiver and QSFP+ active optical fiber (AOC).
The QSFP-40G-DAC-P3M-HW DAC copper cable is programmed to be compatible with a wide range of HW network equipment for intra-rack connections in data centers such as 40G Switches, Routers, Network Interface Cards (NICs) and Network Storage Systems. It’s proven to be a cost-effective alternative to high-cost HW QSFP-40G-CU3M 40Gb/s QSFP+ 3m direct attach the copper cable.
