ExpressPort QSFP+ / QSFP
TM
U90-C101-3000
The ExpressPort™ QSFP+/QSFP interconnect system is comprised of a 38-position 0.8 mm pitch SMT
connector, and a press- t cage designed to comply with the Quad Small Form-factor Pluggable (QSFP)
Transceiver intended for external connections. High speed serial interconnect applications include
clusters, servers, and storage devices.
The ExpressPort™ QSFP+ E-Series and H-Series connector families are rated to 28 Gbps and 40 Gbps
respectively per channel (4x28), featuring a stamped and formed contact design providing improved
mechanical durability. This connector features an integrated grounding structure and resonance
dampening features for superior crosstalk performance. The contact design is optimized for a smooth
impedance pro le resulting in improved SI performance.
Speci cation Highlights
The QSFP interconnect system is comprised of a
press- t cage assembly which is used with
38-position connectors complying with QSFP
Transceiver Speci cations.
