Introduction:
This 4-port shielded SFP 2×2 connector and cage combo integrates four transceiver bays into a dual-row stacked profile to optimize front panel density on system host boards. Built from resilient copper alloy, the unitary structure delivers continuous electrical ground paths and mechanical protection without requiring separate connector soldering. High-temperature UL 94V-0 LCP and thermoplastic housings secure phosphor bronze contacts to maintain signal integrity through frequent transceiver mating cycles. Integrated enhanced LPX light pipes channel PCB-level optical signals to the bezel, providing real-time port link monitoring across upper and lower tiers. Copper alloy EMI spring fingers press flush against chassis cutouts to suppress high-frequency radiation leakage. Solderless press-fit compliant pins anchor directly into PCB plated through-holes, providing mechanical retention while avoiding thermal assembly stress. This stacked combo suits high-density Ethernet switches, optical transceivers, and telecommunication access routers.
