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 flexible format. The cages have a two-piece construction with enhanced transceiver mating tabs available in a press-fit 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. UE78-B8126-00321 UE78-L1126-00321 Specification Highlights The interconnect system is comprised of a cage assembly which is used with 20-position SFP connectors complying with MSA Agreement INF-8074i.
