SFP 2xN
Amphenol’s SFP interconnect system consists of a 20-position connector enclosed in a metal cage
mounted to a host PCB.
Amphenol’s stacked SFP combos are rated up to 6 Gbps. The connector accepts multiple transceivers
per INF-8074i and combines, transmits, and receives functions in a low cost, compact, and exible
format. The cages have a two-piece construction with enhanced transceiver mating tabs available in a
press- t version or a solder tail version. Longer and shorter pins are available as custom options. Stacked
versions (2xN) consist of a 2-row cage with integrated 2-row connectors.
