The ExpressPort™ QSFP+/QSFP Interconnect system is comprised of a 38-position 0.8 mm pitch SMT
connector and a press-fit cage designed to comply with the Quad Small Form-factor Pluggable (QSFP) Transceiver
Specifications. The connector system is capable of data rates beyond 10 Gbps per channel (4 channels) and is
intended for external connections (38-position connector). High speed serial interconnect applications include
clusters, servers and storage devices.
The ExpressPort™ QSFP+ E-series connector family is rated at 28 Gbps 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 profile resulting in low losses. The ExpressPort ™ QSFP+ E-series connector
is designed for IBTA [EDR] applications (25.78 Gbps) and is fully compatible with industry standard SFF-8436
QSFP+ modules. The QSFP+ E-series connector is fully compatible with existing QSFP and QSFP+ cages.
Specification Highlights
The QSFP interconnect system is comprised of a press-fit cage assembly which is used with 38-position,
0.8 mm pitch connectors complying with QSFP Transceiver Specifications.
