ExpressPortTM SFP+ 1xN
Amphenol’s ExpressPortTM SFP+ 1xN connector, when combined with the ExpressPortTM SFP+ cage,
provides data transfer speeds of up to 25 Gbps. The design of the ExpressPortTM SFP+ connector
minimizes impedance discontinuities and reections at high data rates, and provides a 10 to 20 dB
improvement in Near-End Crosstalk.
Amphenol’s unique ExpressPortTM SFP+ cage construction features EMI shielding available in the form of
metal spring ngers or elastomeric gaskets. These cages also eliminate ventilation holes near the front
of the cage to prevent potential catch points for the mating module EMI springs. Additional features
available include lightpipes (which can be purchased with cages or separately), heat sinks, and other
custom features.
