ExpressPort™ SFP+ 1xN
Cage & Connector
U77-C261M-2081
UE76-A20-2001T
U77-A1318-2001
Amphenol’s ExpressPort™ SFP+ 1xN Connector, when combined with the ExpressPort™ SFP+ Cages, provides
data transfers speeds of up to 14 Gbps. The design of the ExpressPort™ SFP+ Connector minimizes impedance
discontinuities and reflections at high data rates, and provides a 10 to 20 dB improvement in Near-End Crosstalk.
Amphenol’s unique ExpressPort™ SFP+ cage construction features EMI shielding available in the form of metal
spring fingers, 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 include light pipes, which can
be purchased with cages or separately, heat sinks, and other custom features.
Specification Highlights
The interconnect system is comprised of a cage assembly which is used with 20-position
SFP+ connectors complying with SFF-8083. Cages comply with industry standard SFF-8433.
