2317434-1 SFP+ CAGE 16 Gbs Through Hole Press-Fit Mount

TE 2317434-1 1x1 SFP+ Cage Assembly

Engineered to deliver exceptional signal integrity and superior mechanical stability in demanding data center and telecommunications infrastructure, the TE 2317434-1 is a premium 1x1 (single-port) SFP+ cage assembly. Designed as a ruggedized cable-to-board mechanical receptacle for high-speed Small Form-factor Pluggable Plus (SFP+) optical transceivers and direct-attach copper (DAC) cables, this shielding cage reliably supports data transmission rates up to 16 Gb/s. Operating as a standalone mechanical housing, it is explicitly designed to envelop discrete surface-mount (SMT) SFP+ electrical connectors, granting hardware architects maximum layout flexibility on the printed circuit board (PCB).

Constructed to endure severe environmental extremes, this cage assembly delivers intrinsic resistance to oxidation and robust mechanical durability across a military-grade temperature range of -55°C to 105°C. Utilizing a highly reliable solderless Through Hole Press-Fit mounting mechanism augmented by an integrated Board Lock feature, the 2317434-1 ensures precise PCB alignment and a permanent, vibration-resistant connection ideal for mission-critical networking hardware.

Single Port Architecture & Board Lock Integration

The discrete 1x1 port configuration serves as an essential mechanical foundation for modular, high-capacity aggregation routers, edge switches, and specialized telecommunications equipment requiring flexible, single-channel transceiver placements.

• Integrated Board Lock: Features specialized mechanical Board Lock retention mechanisms. This advanced structural feature anchors the cage securely to the PCB during the press-fit process, dramatically increasing the retention force and preventing any structural skewing or lifting during frequent transceiver insertions in high-vibration environments.
• Streamlined Front Panel (No Lightpipes): Designed explicitly without integrated lightpipes, this cage offers a clean, low-interference outer profile. This is highly advantageous for custom faceplate bezels or systems that rely on external, chassis-mounted diagnostic LEDs, significantly reducing internal trace routing complexity.

Advanced EMI Containment via External Springs

Managing Electromagnetic Interference (EMI) at 16 Gb/s frequencies is a critical design mandate, especially in densely packed rack environments. The 2317434-1 achieves superior electromagnetic compatibility (EMC) through its advanced shielding construction.

• External EMI Springs: Heavy-duty metallic EMI springs surround the front perimeter of the cage opening. These external springs compress directly against the inner edge of the metallic chassis bezel, creating a continuous 360-degree, low-impedance electrical path to ground, effectively sealing the enclosure against external Radio Frequency Interference (RFI).
• High-Frequency Shielding: The robust metallic structure 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.

Mechanical Design & Press-Fit Manufacturing

Hardware engineers prioritize long-term mechanical reliability alongside high-yield automated manufacturing. The 2317434-1 leverages robust Through-Hole Technology (THT) 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 physical shock and completely eliminates the thermal fatigue associated with secondary wave soldering.
• Extreme Thermal Endurance: The extended -55°C to 105°C operating range ensures uninterrupted physical protection for optics deployed in unconditioned outdoor enclosures, industrial factory floors, and aerospace applications.

Typical Applications

Combining 16 Gb/s performance, robust EMI shielding, military-grade thermal resilience (-55°C to 105°C), and a versatile press-fit integration with Board Lock stability, the 2317434-1 is the optimal mechanical housing for extreme-environment network architectures:

• Defense & Aerospace: Ruggedized military communication hubs, radar systems, and avionics subjected to massive temperature fluctuations and intense mechanical vibration.
• Telecommunications Infrastructure: Broadband access hubs, unconditioned outdoor 5G baseband units (BBUs), and fiber-to-the-x (FTTX) optical line terminals.
• Data Center & Enterprise Switching: High-density 10GbE / 16GFC edge switches, Top-of-Rack (ToR) routers, and core network aggregation devices requiring discrete, standalone cage configurations.
• Industrial & Edge Computing: Hardened industrial Ethernet gateways and micro-data center nodes deployed in harsh manufacturing or energy sector environments.
