TE connectivity QSFP Plus Connectors and Cages

Product Information

The QSFP+ connectors and cages are part of the QSFP+ product family, which provides four channels of data in one pluggable interface. Each channel can transfer data up to 14 Gbps, supporting a total of 56 Gbps. These connectors have 3 times the density of SFP+ interconnects. The QSFP+ product family includes cages in single and ganged configurations with various heat sink and light pipe options. The connector is a 38-position, high-speed SMT connector. EMI plugs are available for empty ports.

TE Connectivity offers PARA LIGHT active optical QSFP+ cable assemblies, which eliminate the need for a separate transceiver and optical interface. The QSFP+ direct attach copper cable assemblies are a high-speed and cost-effective alternative to fiber optics in short-reach 10Gb Ethernet and 14Gb InfiniBand FDR applications. These assemblies enable hardware OEMs and data center operators to achieve higher port density and configurability at a low cost while reducing the power requirement.

Product Usage Instructions

To use the QSFP+ connectors and cages, follow these steps:

1. Select the appropriate QSFP+ connector and cage configuration based on your application needs.
2. If using a cage, install it behind or through the bezel of your device, depending on the selected cage configuration.
3. If required, apply EMI gaskets and springs to ensure electromagnetic compatibility.
4. If needed, attach lightpipes to provide visual indication or illumination.
5. If desired, apply heatsinks for thermal management.
6. If there are any empty ports, insert EMI plugs to prevent EMI interference.

For specific part numbers and descriptions of QSFP+ connectors, cages, EMI gaskets, lightpipes, and other accessories, refer to the product manual or contact TE Connectivity for further assistance.

Introducing QSFP+ Family

Frequently Asked Questions

What data rate does QSFP+ support?
QSFP+ supports up to 10 Gbps per channel Ethernet (40G total) and 14 Gbps per channel InfiniBand (56 Gbps total).
Is TE’s footprint compatible with other suppliers?
The single port cages are designed to industry standards. The ganged versions are not compatible with all sources.
Are heat sinks available?
Yes, TE offers a generous portfolio of heatsink heights and styles, as well as custom heatsinks upon request.
Is application tooling required?
Single port cage assemblies require only flat-rock tooling, while ganged assemblies require specific application tooling.
Does the application follow the performance requirements of SFF-8436?
TE’s QSFP+ copper passive and active cable assemblies meet signal integrity requirements defined by industry standard SFF-8436. A fundamental requirement is the data rate as these cables are engineered for DDR and/or QDR data rates. We can also custom engineer cable assemblies to meet a specific system requirements.
Are passive or active cable assemblies required?
Passive cables have no signal amplification in the assembly and rely on host system Electronic Dispersion  Compensation (EDC) for signal amplification/equalization. Active cable assemblies have signal amplification and equalization built into the assembly and typically used in host systems that do not employ EDC.
If passive cables are needed, is equalization required?
Equalization is the process of reducing distortion over a transmission path by using compensating devices (resistors, capacitors, etc). These equalizers are added to the cable plug PCB and act as filters to improve the cable assembly’s frequency response. These filters reduce jitter and open the cable’s eye pattern.
What cable lengths are required?
Cable length and wire gauge are related to the performance characteristics of the cable assembly. Longer cable lengths require heavier wire gauge, while shorter lengths can use a smaller gauge cable. Smaller gauge cable assemblies provide many benefits to the data center operator, such as ease of routing, less weight and increased airflow. TE offers QSFP/QSFP+ cable assemblies in wire gauges #26 through #33 to support customers’ specific cable routing requirements.
Are there other special customer requirements?
Examples of special requirements include custom cable lengths, EEPROM programming, labeling and packaging. We can custom engineer cables to specific customer system architecture.
