Introduction:
This 4-port SFP 2×2 receptacle and cage assembly combines external shielding and internal mating receptacles into a dual-tier stacked combo unit. Fabricated from corrosion-resistant copper-nickel alloy, the outer frame ensures reliable structural protection and standard electrical grounding continuity across panel cutouts. High-temperature UL 94V-0 LCP and PA46 housings insulate wear-resistant phosphor bronze contacts to preserve signal integrity through repetitive module mating cycles. Integrated enhanced LPX light pipes route board-level LED indicators to the front bezel, allowing real-time monitoring of transceiver activity on both levels. Compliant press-fit pins install directly into PCB plated through-holes, delivering high mechanical retention without thermal solder exposure. This stacked assembly suits high-density managed Ethernet switches, fiber media converters, and enterprise aggregation routers.
