Today’s enterprise data centers and networking environments are undergoing an infrastructure transformation, requiring higher speeds, greater scalability, and higher levels of performance and reliability to better meet the demands of business. As speed and performance needs increase, modern copper cables have become an integral part of overall system design. QSFP+ direct attach copper breakout cables are designed to meet emerging data center and high performance computing application needs for a short distance and high density cabling interconnect system capable of delivering an aggregate data bandwidth of 40Gb/s. These high speed cables provide a highly cost-effective way to upgrade from 10G to 40G or 40G to 40G interconnect connection.
How to Use a 40G QSFP+ Direct Attach Copper Cable QSFP+ direct attach copper cables can be mainly divided into two types. One is QSFP+ to 4 SFP+ direct attach breakout copper cable, and the other is QSFP+ to QSFP+ direct attach copper cable. In fact, there is a third type QSFP+ direct attach copper cable called QSFP+ to 4 XFP breakout cable. Since it is not common, this article may not make discussion. However, regardless of what type of cables, they are both used to connect switch to switch or switch to sever. For a QSFP+ to 4 SFP+ direct attach breakout copper cable, it has a QSFP+ connector on one end and four SFP+ connectors on the other end. In terms of a QSFP+ to QSFP+ direct attach copper cable, it has a QSFP+ connector on both ends of the cable. When we use a fiber optic transceiver and patch cable to establish a fiber link, we should firstly plug the transceiver to the switch and then plug the patch cable to the transceiver. But for a QSFP+ direct attach copper cable, either SFP+ connector or QSFP+ connector, can be both directly inserted into the switch and don’t need a transceiver at all, which provides a really cost-effective solution for interconnecting high speed 40G switches to existing 10G equipment or 40G switches to 40G switches.
40G QSFP+ to 4 SFP+ Direct Attach Copper Cabling The move from 10G to 40G Ethernet will be a gradual one. It is very likely that one may deploy switches that have 40G Ethernet ports while the servers still have 10G Ethernet ports. For that situation, we should use a QSFP+ to 4 SFP+ direct attach breakout copper cable. These cables connect to a 40G QSFP port of a switch on one end and to four 10G SFP+ ports of a switch on the other end, which allows a 40G Ethernet port to be used as four independent 10G ports thus providing increased density while permitting backward compatibility and a phased upgrade of equipment. As a lower cost alternative to MTP/MPO breakouts for short reach applications up to 5 meters, it helps IT organizations achieve new levels of infrastructure consolidation while expanding application and service capabilities.

40G QSFP+ to QSFP+ Direct Attach Copper Cabling QSFP+ to QSFP+ direct attach copper cable are suitable for very short distances and offer a highly cost-effective way to establish a 40G link between QSFP+ ports of QSFP+ switches within racks and across adjacent racks. These cables connect to a 40G QSFP port of a switch on one end and to another 40G QSFP port of a switch on the other end. Supporting similar applications to SFP+, these four-lane high speed interconnects were designed for high density applications at 10Gb/s transmission speeds per lane. One QSFP+ to QSFP+ direct attach copper cable link is equivalent to 4 SFP+ cable links, providing greater density and reduced system cost. Passive and active QSFP+ to QSFP+ direct attach copper cables are both available. With a active QSFP+ to QSFP+ direct attach copper cable assembly, the connection is capable of distances of up to 10 meters.
