2170680-2 Position SFP+ Cage Connector 16 Gb/s Press-Fit Through Hole

TE 2170680-2 1x1 SFP+ Cage Assembly

Engineered to deliver uncompromising signal integrity and robust physical protection in harsh-environment data center and telecommunications infrastructure, the TE 2170680-2 is a premium 1x1 (single-port) SFP+ cage assembly. Designed as a ruggedized, sealable cable-to-board receptacle for Small Form-factor Pluggable (SFP+) optical transceivers and direct-attach copper (DAC) cables, this shielding cage reliably supports high-speed data transmission rates up to 16 Gb/s. As a standalone mechanical cage, it is engineered for use with discrete surface-mount (SMT) SFP+ electrical connectors, granting hardware architects maximum layout flexibility on the printed circuit board (PCB).

Constructed from high-grade Nickel Silver, this cage assembly delivers intrinsic resistance to oxidation and robust mechanical durability across an extreme extended temperature range of -55°C to 105°C. Utilizing a highly reliable solderless Through Hole Press-Fit mounting mechanism, the 2170680-2 ensures a permanent, gas-tight mechanical connection to the PCB without subjecting the motherboard to the thermal stress associated with secondary wave soldering.

Single Port Architecture & Rugged PCB Integration

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

• SMT Connector Compatibility: Meticulously engineered to mate perfectly with standard 20-position SFP+ SMT electrical connectors, ensuring exact mechanical alignment and optimal 16 Gbps signal fidelity.
• Sealable Design: Uniquely designated as a sealable cage assembly, making it highly suitable for IP-rated chassis designs, ruggedized outdoor enclosures, and military-grade hardware subjected to moisture and dust ingress.
• Streamlined Front Panel (No Lightpipes): Designed explicitly without integrated lightpipes, this cage offers a clean, low-interference outer profile. This reduces internal trace routing complexity for applications utilizing external, chassis-mounted diagnostic LEDs or custom, environmentally sealed faceplate bezels.

Advanced EMI Containment via EMI Springs

Managing Electromagnetic Interference (EMI) at 16 Gb/s frequencies is a critical design mandate, particularly in unconditioned environments. The 2170680-2 achieves superior electromagnetic compatibility (EMC) through its advanced shielding construction.

• Active 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 premium Nickel Silver 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.

Mechanical Design & Press-Fit Manufacturing

Hardware engineers prioritize long-term mechanical reliability alongside high-yield automated manufacturing. The 2170680-2 leverages advanced compliant pin 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 mechanical bond that heavily resists vibration, physical shock, and completely eliminates the thermal fatigue of wave soldering.
• Optimized PCB Geometry: This cage is precisely engineered to mount securely onto robust telecommunications logic boards requiring a standard recommended PCB thickness of 1.5mm [0.059in].
