QSFP-DD

The QSFP-DD interconnect system is comprised of a 76-position, 0.8mm pitch connector built for use in high speed serial applications. Each port supports up to 400 Gbps in aggregate over an 8 x 50 Gbps electrical interface. The cage and connector design provides backwards compatibility to QSFP28 modules which can be inserted into a QSFP-DD port and connected to 4 of the 8 electrical channels. It is one of the industry’s leading multi-lane pluggable form factors used across Ethernet, Fibre Channel and InfiniBand.

Environmental Specifications

  • Footprint

    This product is designed to reduce the footprint to allow for more board real estate and capture a slim and small design for your solution.

  • Halogen Free

    Again we want to preserve the earth by making our products free of elements that could harm it. QSFP-DD materials do not contain any compounds derived from harmful halogen elements.

  • Reach Compliant

    QSFP-DD like all other Amphenol products follow the Reach complacency. Some materials are hazardous to the environment and pollute landfills. Amphenol wants to perserve our earth by using non hazardous materials.

  • Flammability

    Flammability Rating UL 94V-0

  • RoHS Complaint

    QSFP-DD like all other Amphenol products follow the RoHS complacency. Some materials are hazardous to the environment and pollute landfills. Amphenol wants to perserve our earth by using non hazardous materials.
