The reduction in insertion force makes assembly easier, faster, and reduces the risk for damage which can lead to reduced EMI performance. EMI sealing enhancements on these new cages provide 10 dB EMI performance improvement over current QSFP28 products.

External riding heatsinks on the upper port are optimized for airflow direction (also available without heatsinks). Air vent holes allow for air to pass through and exit out the sides and rear of the cage.

Designing with these cages allows access to proven technology to support high performance applications. Certain stacked cages can be used in belly-to-belly applications to support high density 2RU+ box designs and switch designs using next-gen 48 and 64 silicon ports. Using a stacked belly-tobelly design enables single PCB architecture versus two PCBs per line card, saving significant system costs.

QSFP28/56 and zQSFP+ Interconnects 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 gauges – from 32AWG up to 26AWG – 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, 100G and 200G 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 • 32AWG up to 26AWG • Straight and breakout assembly configurations available • Customizable EEPROM mapping for cable signature • RoHS compliant • Low smoke zero halogen options available by request • Contact your TE Representative for customized lengths DATA AND DEVICES /// QSFP28/56 AND zQSFP+ INTERCONNECTS PAGE 8 QSFP28/56 and zQSFP+ Interconnects Part Number Detail QSFP28 Cable Assemblies Base Part Number Description 2336313 2333393 2333841 QSFP28 to QSFP28 Straight Assembly AWG Dash to Length (meters) 0.5 1 1.5 2 2.5 3 32 -1 -2 -3 -4 30 -1 -3 -4 28 -1 -2 -5 -6 -7 -3 -4 -5 2333842 26 -1 -2 -3 -4 2340655 32 -1 -2 -3 -4 3.5 4 -6 -7 -8 -5 -6 -7 -8 2333801 QSFP28 to 2xQSFP28 30 -1 -2 -3 -4 -5 -6 2333843 Breakout Cable 28 -1 -2 -3 -4 -5 -6 -7 -8 2333844 26 -1 -2 -3 -4 -5 -6 -7 -8 2340654 32 -1 -2 -3 -4 2334236 QSFP28 to 4xSFP28 30 -1 -2 -3 -4 2334877 Breakout Cable 28 -1 -2 -3 -4 -5 -6 -7 -8 26 -1 -2 -3 -4 -5 -6 -7 -8 0.5 1 1.5 32 -41 -42 -43 30 -41 -43 -44 -45 28 -41 -42 -43 -44 -45 2333841 26 -41 -42 -43 -44 -45 2340655 32 -41 -42 -43 2334878 4.5 5 -9 -10 -9 -10 -9 -10 QSFP56 Cable Assemblies Base Part Number Description 2336313 2333393 2333841 QSFP56 to QSFP56 Straight Assembly AWG Dash to Length (meters) 2 2.5 2333801 QSFP56 to 2xQSFP56 30 -41 -42 -43 -44 2333843 Breakout Cable 28 -41 -42 -43 -44 -45 2333844 26 -41 -42 -43 -44 -45 2340654 32 -41 -42 -43 2334236 QSFP28 to 4xSFP56 30 -41 -42 -43 -44 2334877 Breakout Cable 28 -41 -42 -43 -44 -45 26 -41 -42 -43 -44 -45 2334878 DATA AND DEVICES /// QSFP28/56 AND zQSFP+ INTERCONNECTS 3 -46 -46 -46 PAGE 9 QSFP28/56 and zQSFP+ Interconnects Frequently Asked Questions What data rates do QSFP28/56 and zQSFP+ support? These products provide 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 1xN QSFP28/56 cages are designed to SFF-8663 and are industry standard. TE’s zQSFP+ SMT connector and 2xN assemblies are dual sourced with Molex, LLC. 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.
