40G QSFP+ DAC cable: how much do you know?


FiberMall QSFP+ (Quad Small Form-factor Pluggable Plus) copper direct-attach cables (also known as 40G DAC) are suitable for very short distances and offer a highly cost-effective way to establish a 40-Gigabit link between QSFP+ ports of QSFP+ switches within racks and across adjacent equipment using QSFP ports. These cables are used for 40GbE and Infniband standards, to maximize performance.
The 40G QSFP+ DAC is designed to meet emerging data center and high performance computing application needs for a high density cabling interconnect system capable of delivering an aggregate data bandwidth of 40Gb/s.This interconnect system is fully compliant with existing industry. It is widely applied in 40Gb/s high-speed interconnecting networking applications such as High density data center, high-performance computing (HPC), servers,enterprise networking and storage networks.
FiberMall QSFP 40G Direct Attach Cable meet the standard specifications such as the QSFP MSA and IBTA (InfiniBand Trade Association). The QSFP+ cables support the bandwidth transmission requirements as defined by IEEE802.3ba (40 Gb/s) and Infiniband QDR ( 4×10 Gb/s per channel) specifications.
