This is an MSA compliant 1000Base-CU SFP to SFP direct attach cable that operates over passive copper with a maximum reach of 1. It has been programmed, uniquely serialized, and data-traffic and application tested to ensure it is 100% compliant and functional. Direct Attach Copper (DAC) cables are factory-terminated twinax assemblies that integrate transceiver-style connectors such as SFP/SFP+, SFP28, QSFP+, QSFP28, QSFP-DD and OSFP at both ends, creating a cost-effective, zero-power electrical link for short-reach, high-speed networks. Philipsun. 500 of Siemon's most popular Direct Attach Copper Cables (DACs), enough for 10 typical data center racks, can ship in 5 days or less. Siemon's new North America quick ship program promotes our capability to produce and ship orders directly from the Siemon Manufacturing Facility in Mexico. We offer variable cable length and customization if needed. Advanced customized DAC Cables can go up to 400Gbps. With the features of the low cost, low power consumption and low latency, it is an alternative to optical transceivers for short reach links in high-speed interconnect applications such as Data Center, HPC and enterprise network. 1G SFP to SFP DAC Twinax Cable available in 0.
