Direct Attach Copper Cable Assemblies TE’s QSFP28 and QSFP56 passive copper cable assemblies feature eight differential copper pairs, providing four data transmission channels at speeds up to 28 Gbps NRZ and 56 Gbps PAM-4, and meet 100G Ethernet, 200G Ethernet and Infiniband Enhanced Data Rate (EDR) requirements. Offered in a broad range of wire gages – from 30AWG through 33AWG – this 100G copper cable assembly features low insertion loss and low cross talk. This next generation cable assembly shares the same mating interface with QSFP+ and QSFP28 form factors, making it backward compatible with existing QSFP ports. QSFP28 and QSFP56 form factors can be used with current 40G and 100G applications with substantial signal integrity margin. Features and Benefits • Compatible with IEEE 802.3cd, IEEE 802.3bj, IEEE 802.3by and InfiniBand EDR • Optimized construction to minimize insertion loss and cross talk • Customized 360° cable braid termination limits EMI radiation • Compatible with all existing QSFP connectors and cages • Pull-to-release slide latch design • 30AWG through 33AWG cable • Straight and breakout assembly configurations available • Customizable EEPROM mapping for cable signature • RoHS compliant • Contact your TE Representative for customized lengths Part Number Detail QSFP28 Cable Assemblies QSFP56 Cable Assemblies Dash to Length Dash to Length Base Part Base Part (meters) (meters) Description AWG Description AWG Number Number 1 2 3 0.5 1 1.5 33 -2 2323238 33 -1 -2 QSFP56 Straight 2829040 InfiniBand EDR 200G Ethernet (NRZ) 30 -4 -6 2323239 30 -1 -2 -3 33 -16 -18 2323247 33 -1 -2 QSFP28 Straight 100G QSFP56 Breakout to 2231368 Ethernet (NRZ) 4x SFP56 30 -1 -2 -8 2323248 30 -1 -2 -3 33 -8 2325343 33 -1 -2 QSFP28 Breakout to QSFP56 Breakout to 2821033 4x SFP28 2x QSFP56 30 -1 -10 -2 2325344 30 -1 -2 -3 33 -7 QSFP28 Breakout to 2821309 2x QSFP28 30 -1 -2 -4 DATA AND DEVICES /// zQSFP+ (QSFP28/56) INTERCONNECTS PAGE 9 zQSFP+ (QSFP28/56) Interconnects Frequently Asked Questions What data rate does zQSFP+ support? zQSFP+ provides four data transmission channels at speeds up to 28 Gbps NRZ and 56 Gbps PAM-4 per channel. Is TE’s footprint compatible with other suppliers? TE’s behind bezel cages are not compatible with all sources. TE through bezel 1xN and stacked products are footprint compatible and dual sourced with Molex, LLC. zQSFP+ connectors and cages are designed to meet SFF-8662. Are heat sinks available? Yes, TE offers a generous portfolio of heat sink heights and styles, as well as custom heat sinks upon request. Is application tooling required? Single port cage assemblies require only flat-rock tooling, while 1xN and stacked assemblies normally require specific application tooling.
