F-tone FT21BC01101 2x1 Stacked SFP+ Cage Connector Technical Overview
The FT21BC01101 is an industry-standard 2x1 stacked SFP+ cage assembly with an integrated electrical host connector and dual outer/inner lightpipes engineered for high-density 10Gb/s Ethernet and 16Gb/s Fibre Channel systems. Featuring solderless press-fit PCB mounting, copper alloy construction with 30µ" plating, and external metallic EMI springs, it delivers vertical 2-port I/O consolidation, independent optical LED status indication, and reliable chassis grounding for enterprise switches, SAN storage directors, and industrial telecom infrastructure.
- Mechanical Form Factor: 2x1 Stacked 2-Port Vertical SFP+ Cage Assembly with integrated dual-tier electrical receptacle and dual Outer/Inner lightpipe optics (2.490" L x 0.551" W x 1.005" H).
- Signal Ecosystem Support: Engineered for 10GbE optical transceivers, 16G Fibre Channel modules, and Direct Attach Copper (DAC) cables operating up to 16 Gb/s (SFF-8431).
- Board Mount Technology: Solderless Through-Hole Press-Fit termination, specifically tailored for heavy-duty 2.36mm [.093 in] thick enterprise PCB substrates.
- Cross-Reference Sourcing: Direct footprint-compatible alternative to industry 2x1 stacked SFP+ cage assemblies from TE Connectivity, Molex, and Amphenol for supply chain diversification.
F-tone FT21BC01101 SFP+ Cage Connector Product Overview
FT21BC01101 is an integrated 2x1 stacked SFP+ receptacle and cage assembly featuring outer and inner lightpipe optics, external perimeter metallic EMI spring gaskets, premium copper alloy 30µ" construction, and press-fit PCB mounting. Designed for vertical port expansion on thick multi-layer line cards in enterprise core switches, SAN storage arrays, and industrial networking enclosures, this 2-port stacked assembly integrates the electrical card-edge receptacle inside the cage body, eliminating secondary SMT host connector reflow operations (-40°C to +85°C).
Key Benefits of F-tone FT21BC01101 SFP+ Cage Connector
- Integrated Receptacle & Dual LightPipe Architecture: Houses the dual-tier 40-position electrical connector, metallic copper alloy cage shell, and independent outer/inner lightpipe optics in a single press-fit unit, eliminating separate SMT connector and lightpipe assembly steps.
- Independent Outer/Inner LightPipe Optics: Dual-path lightpipes capture SMT LED light from the PCB and route it separately to the front bezel, providing real-time visual link and activity diagnostics for both upper and lower ports without light bleeding.
- Thick Enterprise Board Matching (2.36mm / .093"): Specifically engineered for thick 2.36mm [.093 in] multi-layer PCB motherboards, ensuring optimal press-fit pin engagement, mechanical retention, and grounding stability.
- Vertical 2x1 Stacked Density Consolidation: Stacks two SFP+ ports vertically in a single column, doubling front-panel port capacity per linear inch of bezel width on 1RU/2RU switch line cards.
- Premium Copper Alloy Construction: Formed with 30µ" plated copper alloy, ensuring low transfer contact resistance, superior wear resistance over repeated module insertions, and enhanced thermal heat dissipation.
- Multi-Source Drop-In Compatibility: Standard SFP+ MSA mechanical footprint enables seamless deployment alongside original OEM equipment for BOM cost optimization and lead-time reduction.
