Tripp Lite's 1m QSFP+ (QSFP Plus) 40GBASE-CR4 / 802.3ba qualified passive copper cable provides next generation performance by combining four 10 Gb/s SFP+ channels into one affordable high-density package. Our QSFP+ cables integrate a new 40G Ethernet-optimized (40GbE) 38-position board-as-connector design with zinc die-cast backshells for superior EMI resistance minimal insertion loss and improved cross-talk performance. Cable featuress 8-pair wire technology optimized for bandwidth-intense applications including 40-Gigabit Ethernet (40GBASE-CR4) 6G SAS Fibre Channel and SONET. Flexible 30 AWG conductors maintain a smooth high-frequency response (20 GHz). Each 1m (3.3-ft) length QSFP+ cable goes through a rigorous assembly and test procedure aimed at eliminating unnecessary signal loss. Our cables are fully compliant to the QSFP+ MSA and SFF-8436 architecture for guaranteed compatibility with all QSFP and QSFP+ ports.N/A- 1 Meter QSFP+ tp QSFP+ 40Gb Passive DAC Copper Infiniband cableN/A- Meets or Exceeds strict 40-Gigabit Ethernet 40GBase-CR4 standardsN/A- SDR DDR and QDR CompatibleN/A- QSFP+ to QSFP+ 30AWG SFF-8436 compliant cable and connectorN/A- Up to 10.3125 Gbps transfer rate per channel ( 40Gb aggregate )N/A- Multi-platform support for 40Gb SAS Fibre Channel and SONETN/A- Zinc die-cast QSFP+ connectors with "Pull-to-Release" latchingN/A- Fully compliant to latest QSFP+ MSA ( Multi Source Agreement )N/A- Lower port cost and reduced power budget vs Fiber Optics
