FT-291-2227316-1 SFP Cage 1 Port 4GB/S Press-Fit Through Hole Without Light Pipe

The FT-291-2227316-1 is a highly ruggedized 1x1 SFP Cage Assembly, engineered to provide superior structural housing and electromagnetic containment for optical and copper transceivers. Rated for data rates up to 4 Gb/s, this single-port receptacle provides the critical physical infrastructure required for Gigabit Ethernet, legacy 4G Fibre Channel (4GFC) Storage Area Networks (SAN), and robust telecommunications transport equipment.

A defining architectural feature of the FT-291-2227316-1 is its Stainless Steel construction. While standard SFP cages often utilize softer copper alloys, stainless steel is explicitly chosen for its exceptional mechanical rigidity and corrosion resistance. This ensures the cage resists structural deformation, port warping, and metal fatigue even when subjected to severe transceiver insertion/extraction torque in high-vibration industrial environments. To ensure strict FCC/CE electromagnetic compatibility, the cage is engineered to provide a tight EMI seal around the chassis bezel, aggressively containing RF leakage from the internal PHY circuitry.

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 of adjacent high-speed signal vias. Notably, this model features an extended 3.0mm tail length paired with a standard 1.5mm recommended PCB thickness. This specific dimensional ratio ensures the EON (Eye-of-Needle) pins fully penetrate and 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 FT-291-2227316-1 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.
