The 2227303-3 is a highly ruggedized, industrial-grade 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 operating in high-vibration environments.

A defining architectural advantage of the 2227303-3 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, this specific cage assembly is optimized for Through-Hole (THT) Solder Termination. Unlike press-fit alternatives, soldered mounting provides exceptional mechanical bonding strength to the FR4 substrate, making it the preferred architecture for ruggedized equipment subjected to severe mechanical shock or sustained vibration. Notably, this model features a precise 1.8mm tail length calibrated for a standard 1.5mm PCB. This results in a minimal 0.3mm sub-board protrusion, making it the definitive architectural choice for custom enclosures with highly restrictive bottom-side chassis clearances or dense double-sided component layouts. Intentionally configured Without a Lightpipe, this minimalist design is ideal for low-profile faceplates.

Built to survive extreme environmental stress, the 2227303-3 boasts an Operating Temperature Range of -55°C to +85°C. This aerospace-level cold-start capability makes it the ideal SFP housing solution for unconditioned outdoor telecom base stations, ruggedized IoT edge gateways, and heavy-industrial control switches.
