SFP
U77-A4114-2001
U77-A1118-2001
Amphenol’s SFP interconnect system consists of a 20-position connector enclosed in a metal cage mounted
to a host PCB.
Amphenol single port and stacked SFP connectors are rated up to 6 Gbps. They are available in standard
RoHS compliant or non-RoHS compliant versions. The cages have a one-piece construction with enhanced
transceiver mating tabs available in press-fit version and solder tail version. Longer or shorter pins are available
as custom options.
Single Row versions (1xN) consist of SMT connectors used with a separate single row cage (press-fit or solder
tail). Stacked versions (2xN) consist of a 2 row cage with integrated 2 row connectors. The entire assembly is
press-fit compliant pin.
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.
