Molex’s zQuad Small Form-factor Pluggable Plus (zQSFP+) interconnect
solution is designed for high-density interconnect applications and conforms
to SFF-8665 QSFP28. Components of the system include SMT connectors
(series 170432); and stacked integrated 2-by-1, 2-by-2 and 2-by-3 connectors
and cages (series 171565). Products scheduled for upcoming release include:
copper passive cable assemblies (Series 111114); EMI cages (Series 111115)
and active optical cables (Series 106412).
Molex’s zQSFP+ SMT connector supports new 100 Gbps Ethernet and
100 Gbps InfiniBand* (IB) Enhanced Data Rate (EDR) applications. EDR
applications consist of four lanes of high-speed differential signals with
individual data rates at 25 Gbps. The preferential coupling design uses a
narrow-edge coupled, blanked- and formed-contact geometry and insert
molding to optimize electrical performance. The zQSFP+ connector shares
the same mating interface as the QSFP+ form factor, making it backward
compatible with current connectors, cages and cable assemblies. Overall
connector length is 2.20mm deeper than the current QSFP+ connector.
zQSFP+ SMT Connector (Series 170432)
Soon-to-be-released zQSFP+ EMI cages will be designed with an advanced
heat-sink system to provide a high level of heat dissipation for next-
generation system-power levels. The spring-finger design will provide optimal
EMI grounding and allow for more space to route high-speed traces.
Future low-power, integrated active optical cable (AOC) solutions will provide
less expensive, reliable transport for aggregated data rates up to 100 Gbps.
The singlemode fiber technology will provide long reaches of up to 4km,
enabling deployment in data centers and campus environments.
