2227317-1 SFP Cage 1 Port 4GB/S Through Hole Press-Fit Mount Without Light Pipe

The 2227317-1 is a highly ruggedized 1x1 SFP Cage Assembly, engineered to provide superior structural housing and aggressive electromagnetic containment for optical and copper transceivers. Rated for data rates up to 4 Gb/s, this single-port physical layer (PHY) receptacle provides the critical mechanical infrastructure required for Gigabit Ethernet, legacy 4G Fibre Channel (4GFC) Storage Area Networks (SAN), and heavy-duty telecommunications transport equipment.

A defining architectural advantage of the 2227317-1 is the pairing of its Stainless Steel body with External EMI Springs. While standard SFP cages frequently utilize softer copper alloys, stainless steel is explicitly selected for its exceptional mechanical yield strength, ensuring the cage resists structural deformation and port warping during severe transceiver insertion/extraction torque. To compensate for this extreme rigidity, the external copper-alloy spring fingers actively compress against the chassis faceplate. In mixed-vendor deployments where sheet metal bezels exhibit unpredictable stamping tolerances, these springs absorb the structural variance. This establishes a continuous, low-impedance 360-degree grounding path, aggressively containing high-frequency RF leakage to ensure strict FCC/CE compliance.

Mechanically, the cage is tailored for high-yield, solderless manufacturing. It utilizes a Through-Hole Press-Fit termination. By eliminating the extreme thermal stress associated with wave soldering, the press-fit architecture preserves the plating integrity and impedance of adjacent high-speed signal vias on the motherboard. Notably, this model features an extended 3.0mm tail length paired with a standard 1.5mm recommended PCB thickness. This deliberate dimensional ratio ensures the EON (Eye-of-Needle) pins fully engage the entire depth of the PCB via, maximizing mechanical retention pull-force. Intentionally configured Without a Lightpipe, this minimalist design is ideal for low-clearance faceplates or headless edge devices.

Built to survive extreme environmental stress, the 2227317-1 boasts an Operating Temperature Range of -55°C to +85°C. This aerospace-level cold-start capability makes it the definitive SFP housing solution for unconditioned outdoor telecom base stations, ruggedized IoT edge gateways, and heavy-industrial control switches.
