2057086-2 SFP+ Cage 16 Gbs Press-Fit Through Hole

TE 2057086-2 1x1 SFP+ Enhanced Cage Assembly with Elastomeric Gasket

Engineered to deliver uncompromising signal integrity and an exceptional faceplate seal in demanding data center and telecommunications infrastructure, the TE 2057086-2 is a premium 1x1 (single-port) SFP+ Enhanced cage assembly. Designed as a ruggedized cable-to-board mechanical receptacle for high-speed Small Form-factor Pluggable (SFP+) optical transceivers and direct-attach copper (DAC) cables, this shielding cage reliably supports high-frequency 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 from high-grade Nickel Silver, this cage assembly delivers intrinsic resistance to oxidation and robust mechanical durability across an extreme military-grade temperature range of -55°C to 105°C. Utilizing a highly reliable solderless Through Hole Press-Fit mounting mechanism, the 2057086-2 ensures precise PCB alignment and a permanent, vibration-resistant connection ideal for mission-critical networking hardware.

Single Port Architecture & PCB 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.

• SFP+ Enhanced Compatibility: Meticulously engineered to meet the physical and electrical demands of SFP+ Enhanced pluggable I/O modules, ensuring exact mechanical alignment with standard SMT connectors for optimal 16 Gbps signal fidelity.
• Optimized PCB Geometry: Featuring a 2.05mm [0.081in] tail length, this cage is engineered to mount securely onto standard telecommunications logic boards requiring a recommended PCB thickness of 1.5mm [0.059in].
• Streamlined Front Panel (No Lightpipes): Designed explicitly without integrated lightpipes, this cage offers a clean, low-interference outer profile. This significantly reduces internal trace routing complexity for applications utilizing external, chassis-mounted diagnostic LEDs or custom faceplate bezels.

Advanced EMI Containment via Elastomeric Gasket

Managing Electromagnetic Interference (EMI) at 16 Gb/s frequencies is a critical design mandate, especially in densely packed rack environments or chassis requiring environmental sealing. The 2057086-2 achieves superior electromagnetic compatibility (EMC) through its advanced gasket shielding construction.

• Elastomeric Gasket Shielding: Unlike standard metallic springs, this cage utilizes a highly compressible, conductive Elastomeric Gasket around the front perimeter of the port opening. This gasket provides a continuous, uniform 360-degree seal against the metallic chassis bezel. This not only creates a low-impedance path to ground to aggressively block external Radio Frequency Interference (RFI), but it also offers superior resistance against dust and particulate ingress at the faceplate.
• High-Frequency Faraday Shield: The robust Nickel Silver structure acts as a continuous Faraday cage, 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 2057086-2 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, gas-tight mechanical bond that heavily resists vibration, 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, an advanced elastomeric gasket for superior EMI and particulate sealing, military-grade thermal resilience (-55°C to 105°C), and a versatile press-fit integration, the 2057086-2 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 requiring tight environmental sealing at the chassis faceplate.
• Telecommunications Infrastructure: Broadband access hubs, unconditioned outdoor 5G baseband units (BBUs), and fiber-to-the-x (FTTX) optical line terminals operating in dusty or harsh environments.
• 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.
