Introduction
For high-speed switching, routing, and server NICs, serviceability and EMI control matter as much as bandwidth. The 1×1 SFP Cage Kit (Model DW-SFP-0032-01) is a compact SFP+ cage assembly that houses hot-pluggable optical or copper SFP+ modules while protecting signals with an EMI shielding cage and a positive pull-link latch. The kit’s mechanical stack prioritizes tool-free module service, reliable retention under vibration, and clean panel fit—exactly what production network gear needs.
What the 1×1 SFP Cage Kit includes (and why it matters)
- Zinc alloy cage (base + upper cover): a rigid, conductive shell for EMI containment and chassis grounding.
- Pull-link latch (black TPV + metal): ergonomic, gloved-hand friendly control for quick, confident extraction of hot-pluggable modules.
- Grounding springs (SUS304): resilient contact points that stabilize emissions and ESD performance.
- Tail sleeve strain relief (TPU): manages cable exits and reduces connector-end stress.
- Stainless hardware (SUS304 screws): durable fasteners for assembly and rework.
Together, these parts create a hot-pluggable module housing that installs cleanly, holds firmly, and releases on command—without tools and without compromising compliance margins.
1×1 SFP Cage Kit design advantages you can specify
- EMI shielding cage: full-coverage metal seams reduce common-mode radiation and improve immunity.
- SFP+ cage with pull-tab: faster swaps in tight racks; shorter maintenance windows.
- Grounding springs: low-impedance contact to the module belly preserves signal reference across temperature and vibration.
- Tail sleeve strain relief: neater cabling at the bezel with fewer snag points during recabling.
- RoHS & REACH compliant, Halogen-Free construction for global deployments.
1×1 SFP Cage Kit materials & construction (built for uptime)
The formed zinc alloy cage provides stiffness for precise bezel alignment and repeatable insertion force. A mating top cover closes the current path around the transceiver shroud, turning the assembly into a continuous EMI shielding cage. The grounding springs maintain pressure over service life to preserve contact integrity, while the pull-link latch engages the transceiver bail for positive retention. The tail sleeve strain relief controls bend radius so patch cables don’t lever against the optics during moves or vibration—small details that pay off in real data-center conditions.
1×1 SFP Cage Kit — application fit
- Ethernet switchboards & routers using hot-pluggable SFP+ optics
- Data-center transceiver mounts and server NICs that require quick field replacement
- Telecom equipment enclosures where airflow, EMI performance, and turnaround time are critical
1×1 SFP Cage Kit — layout & integration notes
- Panel alignment: keep bezel openings square to the cage face to prevent scrape and ensure smooth module travel.
- Ground stitching: provide short, multiple ground points from the zinc alloy cage to chassis; avoid long loops that erode shielding effectiveness.
- Thermal/airflow: leave unobstructed exhaust paths above the module belly; avoid tall components near cage vents.
- Assembly sequence: seat the SFP+ cage assembly, secure with stainless hardware, then fit the pull-link latch and tail sleeve strain relief last to avoid handling damage.
- Serviceability: mark pull-tab direction on the bezel for faster technician workflows and fewer blind pulls.
