Description
Amphenol’s ExpressPort
provide data transfer speeds of up to 10 Gbps when combined with the new ExpressPort
connector. Together, these products form a modular high speed I/O interconnect system providing a
higher speed, inexpensive External I/O product, primarily for the networking, telecom and storage
systems markets.
ExpressPort
and SFF-8433 standard for 1xN (1x2, 1x4 and 1x6) port versions, and feature compliant press-fit
pins (single port cages are also available with pcb mount solder tails)
Amphenol’s unique ExpressPort
of metal spring fingers that interface with the panel cut-out, or an elastomeric gasket that is
compressed between the cage flange and the rear surface of the mounting panel.
The EMI spring finger tabs are spot-welded to the cage in a continuous strip to provide improved
EMI sealing, with “kinkless” tabs to reduce the potential for damage to the tabs during assembly to a
chassis panel.
The Elastomeric sealing gasket is captured by features on the flange, preventing gasket creep, and
maintaining alignment for reliable EMI sealing.
These cages also feature the removal of ventilation holes near the front of the cage to eliminate
potential catch points for the mating module EMI springs.
Additional features include available lightpipes (2 lightpipes per port), which can be purchased with
cages or separately, heat sinks, and other custom features.
The ExpressPort
proven card edge style contacts with refined geometries, providing gigabit data transmission signal
capabilities to 10 Gbps, with a more linear impedance profile. This new design minimizes
impedance discontinuities and reflections at high data rates, and provides a 10 to 20 dB Improvement
in Near-End Crosstalk, allowing the use of longer copper cables, improved pcb routing, resulting in
an overall lower interconnect loss budget.
Applications
The demand for higher data rates, improved electrical performance and supression of EMI generated
by higher frequencies are driving the development and availability of SFP+ products with more
features and configurations for use in both Telecom and Datacom applications using 10 Gb Ethernet
and 8Gb Fibre Channel.
