QSFP+ (Quad Small Form-factor Pluggable Plus) Cable Assemblies 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 racks. QSFP+ cables are used for 40 GbE and Infniband standards, to maximize performance. We now provide several lengths to accommodate your installation requirements, welcome to buy it from FiberStore.We offer the 40G QSFP+ copper cables with lengths ranging from 0.5m to 10m.QSFP+ Active Optical Cable (AOC) is a high performance, low power consumption integrated cable for short-range multi-lane data communication and interconnect applications, supporting 40G Ethernet, fiber channel and PCIE. It is compliant with the QSFP MSA and IEEE P802.3ba 40GBASE-SR4. It integrates four data lanes in each direction with 40 Gb/s aggregate bandwidth. Each lane is capable of transmitting data at rates up to 10Gb/s with lengths ranging from one to 100 m.QSFP+ to 4 SFP+ hybrid splitter cables make a great cost-effective interconnect solution to IT professionals by providing much needed space for data centers and cost cuts. These cables allow you to connect your QSFP+ and SFP+ Switches and Network cards without upgrading your entire data center or storage array.
