The 1×1 SFP Cage Assembly with Press-Fit EMI Housing integrates a stamped copper-alloy shielding shell and a 20-position 0.8 mm right-angle press-fit receptacle into one pick-and-place unit. It is the smallest SFP I/O building block: one transceiver slot, smallest front-panel cutout (~15.25×6.5 mm), no soldering, no light pipe, no heat sink — exactly the configuration TE documents as 2170039-1 ("Single Cage, External Springs, No Lightpipe, Heat Sink Compatible: No").
It accepts SFP, SFP+, and SFP28 optical transceivers, DAC and AOC, and mounts to the host PCB via compliant press-fit pins — making it the default choice for single-uplink media converters, 1-port NICs, industrial DIN switches, protocol converters, and diagnostic/test cards where software/NMS handles port status and EMI containment is non-negotiable.

Product Selection Reminder
1, Confirm form factor: SFP / QSFP / QSFP-DD / XFP / CFP. Different specifications cannot intermate mechanically.
2, Confirm port layout: single port or stacked 2×2, straight or right-angle mounting.
3. Confirm optional parts: whether light pipe, heat sink or dust cover is required.
4. Confirm PCB assembly method: SMT soldering or press-fit pins.
5. Confirm maximum transmission rate requirement to select a matched impedance structure.
