Designed to be mounted inside a corresponding SFP metal cage assembly, this right-angle electrical interface provides the critical physical layer (PHY) bridge between the host motherboard and pluggable fiber optic or copper transceivers. Conforming to strict SFF Committee MSA (Multi-Source Agreement) standards, it is the foundational electrical building block for enterprise routing, telecom switching, and high-speed network interface cards (NICs).\u003c\/p\u003e\n\u003cp\u003eElectrically, the FT-291-11B000001 is engineered for uncompromising high-bandwidth signal integrity.

Unlike through-hole (THT) connectors that introduce parasitic capacitance and signal-degrading via stubs, the SMT architecture allows PCB layout engineers to route high-speed differential pairs (TX\/RX) cleanly on the top layer or through strictly controlled microvias. This layout flexibility dramatically minimizes impedance mismatches and return loss at Gigabit and multi-Gigabit speeds.
