- Board Mount Technology: Solderless Through-Hole Press-Fit termination with 2.05mm tail length, optimized for 1.5mm recommended PCB thickness.
- Alternative Sourcing Option: Multi-source engineering options are available to support secondary sourcing strategies, BOM cost optimization, and supply chain flexibility.
TE Connectivity 2057555-1 SFP+ Cage Assembly Product Overview
TE Connectivity 2057555-1 is a 1x2 ganged SFP+ cage assembly featuring external EMI spring gaskets, nickel silver alloy construction, and press-fit PCB mounting designed for high-density I/O interfaces in enterprise storage, data center switching, and telecom networking equipment. The 2-port ganged configuration offers mechanical retention, low transfer impedance EMI shielding, and PCB mounting support for dual SFP+ optical transceivers and copper interconnects.
Key Benefits of TE Connectivity 2057555-1 SFP+ Cage Assembly
- High-Density Dual-Port Integration: 1x2 ganged architecture doubles front-panel port density compared to discrete single-port cages, optimizing line card real estate.
- 16 Gb/s Data Rate Capability: Supports high-speed serial protocols including 10G Ethernet (10GbE), 8G/16G Fibre Channel (FC), and CPRI wireless interfaces.
- Robust EMI Containment: External metallic spring gaskets establish continuous grounding against chassis cutouts to suppress high-frequency electromagnetic leakage.
- Extended Thermal & Mechanical Endurance: Durable nickel silver alloy construction maintains mechanical spring resilience across an extended operating temperature range of -55°C to +105°C.
- Solderless Manufacturing Flexibility: Press-fit compliant pins enable automated PCB assembly without subjecting sensitive board components to reflow solder thermal stress.
- Multi-Source Availability: Industry-standard footprint enables secondary sourcing strategies to improve supply chain resilience, lead-time management, and BOM optimization.
