FT22AC01101 SFP 2x2 Cage Connector Press-Fit With InnerOuter Light Pipe

F-tone FT22AC01101 2x2 Port SFP Stacked Cage with Inner/Outer Light Pipes

Engineered to maximize faceplate I/O density in demanding data center and telecommunications environments, the F-tone FT22AC01101 is a highly robust 2x2 (4-port) stacked SFP cage assembly. By organizing four Small Form-factor Pluggable (SFP) ports into a compact, ganged 2x2 matrix (28.75mm overall width), this right-angle cage empowers hardware architects to significantly increase port capacity on standard 1U or 2U networking chassis. Designed to envelop and shield PCB-mounted electrical receptacles, this cage provides essential mechanical alignment, structural protection, and thermal dissipation for high-speed pluggable transceivers.

Constructed from a premium Nickel-Plated Copper Alloy, this heavy-duty cage delivers superior structural rigidity and uncompromising resistance to corrosion. Featuring an extreme industrial operating temperature range of -40°C to +85°C, the LP22AC01101 guarantees mission-critical reliability for both climate-controlled enterprise data centers and unconditioned outdoor edge computing enclosures.

Integrated Inner & Outer Light Pipes for Visual Diagnostics

Providing clear, port-level diagnostic feedback in high-density 2x2 stacked configurations is a complex mechanical challenge. The FT22AC01101 definitively resolves this by incorporating precision-engineered Inner and Outer Light Pipes directly into the cage architecture.

• Comprehensive Port Visibility: These dedicated optical channels efficiently capture light from surface-mounted LEDs located on the PCB and route it directly to the front chassis bezel for both the upper and lower port rows simultaneously.
• Simplified Troubleshooting: Provides network administrators with immediate, unambiguous visual status indicators (such as Link Speed and Network Activity) for all four ports, without compromising the cage’s electromagnetic shielding or requiring complex external LED light-guides.

Advanced EMI Containment & Shielding

Managing Electromagnetic Interference (EMI) in high-density, multi-port chassis configurations is a critical design mandate. The FT22AC01101 achieves superior electromagnetic compatibility (EMC) through its advanced shielding construction.

• Nickel-Plated Copper Construction: The premium alloy acts as a continuous Faraday shield, aggressively containing internal high-frequency emissions generated by the PHY transceivers and ensuring strict compliance with FCC, CE, and CISPR regulatory standards.
• Active EMI Springs: Heavy-duty metallic EMI springs surround the perimeter of the port openings. These springs ensure continuous, low-impedance electrical contact with the metallic chassis bezel, aggressively sealing the enclosure against external Radio Frequency Interference (RFI).
• Port-to-Port Isolation: Internal metallic dividers between the upper and lower ports, as well as between adjacent columns, act as physical and electrical barriers. This dramatically reduces near-end crosstalk (NEXT) and electromagnetic coupling across the 4-port matrix.

Mechanical Design & Press-Fit PCB Integration

Hardware engineers prioritize long-term mechanical reliability alongside high-yield automated manufacturing. The FT22AC01101 leverages advanced solderless technology to optimize the PCB assembly workflow.

• Press-Fit (Compliant Pin) Technology: The cage utilizes a Through-Hole Press-Fit mounting style. The compliant pins are driven directly into plated through-holes (PTH) on the PCB, creating a cold-welded, gas-tight mechanical bond that heavily resists vibration, physical shock, and completely eliminates the thermal stress associated with secondary wave soldering.
• Tray Packaging for Automation: Supplied in standard tray packaging, ensuring component protection during transit and seamless integration into automated factory floor pick-and-place assembly lines.

Typical Applications

Combining massive stacked port density, targeted visual diagnostics, industrial-grade thermal resilience, and a robust press-fit design, the FT22AC01101 is the optimal interconnect housing for high-throughput network architectures:

• Data Center & Enterprise Switching: High-density Top-of-Rack (ToR) switches, core edge routers, and network aggregation devices demanding visually monitored, space-saving stacked port matrices.
• Telecommunications Infrastructure: Broadband access hubs, 5G baseband units (BBUs), and fiber-to-the-x (FTTX) optical line terminals (OLTs).
• Storage Area Networks (SAN): High-throughput Fibre Channel storage arrays and host bus adapters (HBAs) requiring dense physical layer protection.
• Industrial & Edge Computing: Ruggedized industrial Ethernet switches and micro-data center nodes deployed in extreme temperature environments (-40°C to +85°C).
