Description
Springtek 100G QSFP28 to 4x 25G SFP28 direct attach passive copper cable are suitable for very short distances and offer a highly cost-effective way to establish a 100-Gigabit link between QSFP28 and SFP28 equipment connections. These cables are used for 100GbE and Infniband standards, to maximize performance. The Hybrid cables are 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 100Gb/s. This interconnect system is fully compliant with existing industry standard specifications such as the QSFP MSA and IBTA (InfiniBand Trade Association). The Hybrid cables support the bandwidth transmission requirements as defined by IEEE 802.3ba (100 Gb/s) and Infiniband QDR ( 4x25 Gb/s per channel) specifications.
