QSFP+ High-Speed Copper Cable Assemblies TE Connectivity’s QSFP+ direct attach copper cable assemblies are a high-speed, cost-effective alternatives to fiber optics in Ethernet, Fibre Channel and InfiniBand technology applications. The cable assemblies enable hardware OEM’s and data center operators to achieve higher port density and configurability at low costs--while helping to reduce power consumption. The QSFP copper cable form factor uses 8 differential pairs that provide 4 data transmission channels. The cable assemblies meet or exceed the industry MSA for signal integrity performance. The TE QSFP+ cable assembly portfolio includes a wide range of options for simplified cable management. In addition to the standard 30, 28 and 26 AWG QDR TurboTwin offerings, TE offers fine gauge 33 AWG 8-pair cable assemblies. These slim versions satisfy the need for ultra-thin, light-weight, highly flexible cabling solutions for use in high density intra-rack applications. For applications that require high flex cycle life, TE offers QSFP+ cable assemblies built with Madison Cable brand InfiniTwist bulk cable. These cables use twisted parallel-pair cable technology to improve bend radii, limit conductor pistoning and increase the dynamic flex cycle life. TE offers passive and active versions of QSFP+ straight and breakout copper cable assemblies. te.com/products/QSFP APPLICATIONS INDUSTRY STANDARDS • Switches & Networking • 40 Gigabit Ethernet • Enterprise storage • InfiniBand QDR/FDR • Telecommunication equipment • Fibre Channel / Fibre Channel over Ethernet (FCoE) • Network interface cards (NICs) • Serial Attached SCSI (SAS) • SONET/SDH • SFF-8635 KEY FEATURES AND BENEFITS • Compatible with IEEE 802.3ba and Infiniband QDR/FDR • Supports data rates of 40 Gbps and 56 Gbps • Offers 3x the port density over SFP form factors • Optimized design minimizes insertion loss and cross talk • Low power consumption • Compliant with RoHS • Enhanced EMI suppression • Pull-to-release slide latch design • 26 AWG through 33 AWG • Available in passive and active versions • Uses Madison Cable brand TurboTwin parallel pair and InfiniTwist twisted parallel pair cables Part Number Selection Guide Base P/N Description Data Rate Cable Type AWG EQ 33 2053638 QSFP+ QDR/CR4 10Gbps TurboTwin 30 28 Cable Assembly Lengths (meters) .5 1 1.5 2 2.5 3 3.5 -3 -25 4 Passive -16 -1 -23 -2 -24 10Gbps InfiniTwist 28 2220639 2053453 QSFP+ QDR/CR4 QSFP+ to [4] SFP+ break out 10Gbps TurboTwin 28 Active 30 10Gbps TurboTwin 28 -2 -3 -1 -2 -3 -1 -2 -3 -4 Passive -4 -5 -4 -5 2231640 break out 10Gbps TurboTwin 14Gbps TurboTwin 30 28 QSFP+ FDR 28 26 te.com/products/QSFP 10 11 12 13 -8 -9 -10 -11 -12 -13 -8 -9 -10 -11 -12 -13 -6 Active 30 2202165 -7 9 -5 26 QSFP+ to [4] SFP+ -6 8 -1 Passive 26 30 7 -5 30 QSFP+ QDR/CR4 6 -4 26 2231705 5 -30 -31 -32 -33 -34 -1 -2 -3 -4 -5 -6 -7 -1 Passive -2 -3 -4 While TE has made every reasonable effort to ensure the accuracy of the information in this brochure, TE does not guarantee that it is error-free, nor does TE make any other representation, warranty or guarantee that the information is accurate, correct, reliable or current.
