4-2338495-1 TE OSFP Cage Ganged (1 x 4) Connector Included Lightpipe

Key Benefits of TE Connectivity 4-2338495-1 OSFP Cage Assembly

• Ultra-High 1x4 Quad-Port Density (Up to 3.2 Tbps Aggregate Bandwidth): Consolidates four 800G OSFP ports into a single integrated 1x4 housing, maximizing front-panel I/O throughput in 1RU/2RU switch chassis.
• Integrated 4-Lightpipe Optic Array: Pre-assembled 4-lightpipe optical assembly guides SMT LED light from the PCB cleanly to the front faceplate, providing clear visual link and activity status indication for all four ports.
• High-Speed Optical Interface Integration: Supports next-generation OSFP optical transceivers, Active Optical Cables (AOCs), and Direct Attach Copper (DAC) interconnects used in 400G and 800G networking platforms.
• Advanced EMI Containment for 112G PAM4: Heavy-duty metallic cage construction and perimeter EMI spring gasket contacts help minimize electromagnetic leakage around pluggable interfaces at high Nyquist frequencies (28 GHz).
• Solderless Press-Fit Manufacturing Flexibility: Precision compliant press-fit pins simplify board assembly, increase manufacturing yields, and avoid additional solder reflow thermal exposure on multi-layer PCB substrates.
• Multi-Source Availability: Industry-standard footprint allows deployment alongside compatible replacement alternatives from qualified suppliers like LINK-PP for BOM cost optimization.

1x4 OSFP Cage Architecture & 400G/800G MSA Compliance

Designed around OSFP MSA mechanical requirements (Rev 4.0/5.0), the TE Connectivity 4-2338495-1 is a 1x4 ganged (four side-by-side ports) OSFP cage assembly. It serves as the physical chassis foundation required to house high-speed 400G (8x50G PAM4) and 800G (8x100G PAM4) optical transceivers, AOCs, and DAC interconnects on high-density line cards.

Quad-Port Ganged Architecture & Signal Integrity Optimization

The ganged 1x4 port matrix layout provides system hardware designers with an optimal balance between port density and PCB trace routing budget. Consolidating four ports into a single housing establishes precise port-to-port pitch across the chassis front bezel, simplifies high-speed 100Ω differential pair routing, minimizes channel insertion loss variability to surface-mount (SMT) OSFP electrical connectors, and prevents trace congestion on ultra-dense line cards.

How to Select and Verify an OSFP Cage Assembly Replacement

When evaluating or sourcing 1x4 ganged OSFP cage assemblies with lightpipes for new line card designs or supply chain diversification, hardware engineers should verify the following core parameters:

• Lightpipe Optic Array Alignment: Confirm that the 4-lightpipe optic assembly matches your front-panel indicator window layout to ensure clear, unbleed LED link status indication for all 4 ports.
• Port Matrix & Density Requirements: Confirm that a 1x4 ganged single-row footprint aligns with your front panel faceplate cutout and PCB differential trace routing budget.
• Signal Integrity & Data Rate Compliance: Ensure the cage design complies with IEEE 802.3ck specifications for 112Gb/s PAM4 per-lane signaling, maintaining 100Ω differential impedance matching.
• PCB Hole Layout & Press-Fit Tail Geometry: Confirm that PCB plated through-hole (PTH) drill diameters and copper plating thickness meet compliant pin press-fit insertion force specifications.
• Mechanical Drawing Verification: Check mechanical tolerances, grounding spring deflection dimensions, and physical envelope parameters against official drawings when qualifying alternative suppliers like F-tone.
