zSFP+ (SFP28) 28 GBPS PLUGGABLE I/O INTERCONNECT The zSFP+ interconnect is currently one of the fastest single-channel I/O connectors on the market today, transferring data at 28 Gbps with possible expansion to 40 Gbps. Through a design that is backward-compatible to SFP/SFP+ products, the interconnect is hot-swappable with existing SFP+ connectors for fast system upgrades of 28-40Gbps. Alternatively, users can design-in the zSFP+ connector for 10-16 Gbps data rates, establishing a progressive path to higher speeds–an upgradeability that can result in longterm cost savings as this would eliminate the need to fully redesign for higher performance. The zSFP+ interconnect is compliant to SFF-8402 and has been adopted for Fibre Channel 32G (28.05 Gbps line rate). The entire product family is offered as a dual source option with Molex. LLC.

Offered in a broad range of wire gages – from 30AWG through 33AWG – this next generation copper cable assembly features low insertion loss and low cross talk. Our SFP28 assemblies share the same mating interface with SFP+ form factors, making them backward compatible with existing SFP+ I/O ports. SFP28 cable assemblies can be used with legacy 10G Ethernet and 16G Fibre Channel applications with substantial signal integrity margin. In addition to SFP28 straight cables, we offer break out assemblies with a 100G QSFP28 module on one end splitting to four SFP28 modules on the opposite end of the assembly. In-line signal integrity (SI) based production testing ensures that each cable assembly meets the electrical performance requirements of the applicable industry standard specification. Features and Benefits • Compatible with IEEE 802.3by and Fibre Channel industry standards • Supports single lane data rate up to 28Gbps • Optimized construction to minimize insertion loss and cross talk • Customized cable braid termination limits EMI radiation • Backward compatible with existing SFP+ form factor connectors and cages • Pull-to-release latch design • 30AWG through 33AWG cable • Straight and breakout cable assembly configurations available SFP28 to SFP28 Straight Cable Assembly • Customizable EEPROM mapping for cable signature • RoHS compliant Industry Standards • 25G Ethernet (IEEE 802.3by) • Fibre Channel • SFF-8402 SFP+ 1X 28Gb/s Pluggable Transceiver Solution (SFP28) • SFF-8665 QSFP+ 28G 4X Pluggable Transceiver Solution (QSFP28) QSFP28 to 4x SFP28 Breakout Cable Assembly Part Number Detail Base Part Number Description 2821262 SFP28 to SFP28 Straight 33 2821222 Assembly 30 2821033 AWG Dash to Length (meters) 0.5 1 1.5 2 -1 -2 -3 -4 -5 -3 QSFP28 to 4x SFP28 33 -8 Breakout Assembly 30 -1 3 -2 -1 -10 -2 4 5 Contact your TE Representative for customized lengths and breakouts.
