F-tone FT-291-11B000001 SFP+ 1x1 Receptacle Connector | 20-Position SMT (10G/16G)
The F-tone FT-291-11B000001 is a premium, industrial-grade SFP+ 1x1 Receptacle Connector. Engineered as the core internal electrical interface for standard SFP+ optical transceivers and Direct Attach Copper (DAC) cables, this 20-position Surface Mount (SMT) connector enables ultra-high-speed data transmission for 10 Gigabit Ethernet (10GbE) and 16G Fibre Channel applications.
Manufactured under rigorous quality control protocols, the F-tone FT-291-LP11B000001 guarantees exceptional signal integrity, precise mechanical mating, and high-cycle durability. The component is fully compliant with the SFF-8431 Multi-Source Agreement (MSA) standard and maintains global safety and environmental certifications, including UL 94V-0 flammability ratings, RoHS, and REACH, ensuring seamless integration into mission-critical datacenter and telecom hardware.
Expert Architecture Insight: High-Speed SMT & LCP Housing
Engineering Notice: While external SFP+ cages often utilize through-hole pins, the internal 20-position electrical receptacle must utilize a Surface Mount Technology (SMT) footprint. This completely eliminates through-hole stub effects, minimizing parasitic capacitance and ensuring pristine eye diagrams at 10+ Gbps data rates.
To support high-yield automated manufacturing, the housing is molded from LCP MG350 (Liquid Crystal Polymer). This advanced thermoplastic boasts extraordinary dimensional stability. It effortlessly withstands the extreme thermal stress of modern IR reflow soldering profiles (up to 260°C) without warping. This guarantees perfect coplanarity of the 20 contact pins, preventing open solder joints and drastically reducing PCB assembly defect rates.
Technical Features & Electrical Performance
Designed for reliability in demanding environments (-40°C to +85°C), this receptacle connector ensures superior electrical conductivity:
- High-Performance Terminals: Fabricated from C5210-EH Phosphor Bronze (T=0.20+/-0.01mm). This provides superior spring characteristics, maintaining strict normal force against the inserted optical module to ensure low contact resistance over repeated hot-swapping cycles.
- Industrial Thermal Endurance: Operates flawlessly across an extreme -40°C to +85°C thermal range, meeting the rigorous demands of outdoor telecom enclosures and densely packed server racks.
- MSA Compliant 20-Position Interface: Features the universally standardized 20-pin layout, making it fully interoperable with all MSA-compliant SFP, SFP+, and high-speed twinax DAC connectors.
Typical Applications & Industry Use Cases
Due to its high-temperature LCP construction and 10Gbps+ signal integrity, the FT-291-11B000001 is the preferred electrical receptacle for:
- Data Center Networking: 10G/40G Top-of-Rack (ToR) and Spine-and-Leaf switches, and high-density Network Interface Cards (SmartNICs).
- Telecom Infrastructure: 5G baseband units (BBU), optical transport networks (OTN), and outdoor edge routers exposed to extreme temperatures.
- Storage Area Networks (SAN): 8G and 16G Fibre Channel host bus adapters (HBA) and clustered storage arrays.
- Industrial Automation: Ruggedized Industrial PCs (IPC) and edge computing gateways requiring pluggable high-speed optical I/O.
