TE 2149490-5 SFP+ Cage 2x8 Port With Integrated Connector Press-Fit Through Hole Included Lightpipe

Product Specifications

Key Benefits of TE Connectivity 2149490-5 SFP+ Cage Assembly

• Integrated 320-Position Receptacle, Cage & Lightpipe Architecture: Houses the 16-port 320-position electrical connector, metallic 2x8 cage shell, and optical lightpipes into a single press-fit assembly, eliminating separate SMT host connector reflow and lightpipe mounting steps.
• Integrated Optical Status Diagnostics: Pre-assembled lightpipe channels guide light from surface-mount LEDs on the PCB cleanly to the front bezel, providing clear visual link and activity status indication for all sixteen stacked ports.
• Maximum 2x8 16-Port Density Consolidation: Arranges sixteen SFP+ ports in a 2-row by 8-column matrix, dramatically increasing front-panel I/O capacity per linear inch of faceplate width on 1RU/2RU switch line cards.
• Solderless All-Press-Fit PCB Assembly: 3.0mm [.118 in] press-fit tails terminate all 320 signal/ground contacts and cage retention legs into plated through-holes in a single press operation, avoiding thermal reflow stress on the board substrate.
• Enhanced EMI Spring Shielding: External perimeter metallic spring gaskets establish continuous, low-impedance grounding against front-panel bezel cutouts across all sixteen stacked ports.
• Multi-Source Availability: Industry-standard mechanical footprint enables secondary sourcing strategies to improve supply chain flexibility, lead-time management, and BOM optimization.

2x8 Stacked 16-Port Architecture with Integrated Connector & Lightpipes

Engineered in compliance with SFP+ MSA (SFF-8431) mechanical specifications, the TE Connectivity 2149490-5 features a 2x8 stacked (two rows high by eight columns wide) architecture containing an integrated 320-position (20 pins per port x 16 ports) card-edge connector and precision lightpipes. This all-in-one housing guarantees perfect alignment between electrical contacts, cage openings, and front bezel optical indicators.

Visual Port Diagnostics & 3.0mm Press-Fit Tail Integration

The integrated optical lightpipes capture light emitted from PCB surface-mount LEDs and project it to front faceplate indicator ports above and below each socket. The right-angle board mount structure features a 3.0mm [.118 in] tail length engineered specifically for standard 1.5mm [.059 in] thick PCB motherboards, ensuring reliable compliant pin compression for all 320 dual-tier receptacle signal contacts and cage retention legs inside multi-layer plated through-holes (PTH).

Enhanced EMI Shielding with External Spring Contacts

Operating sixteen adjacent ports at high-frequency 16 Gb/s serial rates requires rigorous electromagnetic compatibility (EMC) design to control radiated emissions and prevent channel crosstalk between adjacent vertical and horizontal ports.

360-Degree External EMI Shielding Springs

The TE Connectivity 2149490-5 incorporates external perimeter metallic spring contacts around all sixteen port openings. When inserted through the front panel, these springs establish low-impedance grounding against the chassis bezel cutout, forming a continuous Faraday shielding barrier across the entire 2x8 16-port interface.

Corrosion-Resistant Nickel Silver Construction

Formed from high-conductivity nickel silver, the cage housing delivers superior mechanical stiffness, wear resistance over repeated module insertion/extraction cycles, and long-term corrosion protection across an extended operating temperature range of -55°C to +105°C. This supports system-level EMC design requirements for equipment targeting FCC and CE compliance.

Press-Fit SFP+ Integrated Receptacle Assembly & PCB Integration

Designed for automated, high-reliability solderless PCB manufacturing, the 2149490-5 utilizes precision compliant press-fit pin technology for signal, power, and ground contacts.

Solderless All-Through-Hole Press-Fit Termination

The combined assembly installs mechanically into host PCB plated through-holes (PTH) using a single controlled press insertion tool. This solderless Through-Hole Technology (THT) eliminates high-temperature SMT reflow ovens or secondary wave soldering operations, preserving high-speed signal integrity and simplifying line card production rework.

Target Applications: Enterprise Switches, SAN Storage Directors, and Telecom

Combining SFP+ MSA compliance, 2x8 16-port stacked density, integrated lightpipes, and press-fit receptacle technology, the TE Connectivity 2149490-5 supports high-density networking systems:

• High-Density Enterprise Switches & Routers: Ideal for 10GbE Top-of-Rack (ToR) switches, enterprise core routers, and aggregation line cards requiring 2x8 16-port stacking and visual status diagnostics.
• Enterprise Storage Area Networks (SAN): Deployed in 16G Fibre Channel core director modules, SAN storage expansion chassis, and high-port-count controllers.
• Telecom Edge Infrastructure: Suitable for 10G CPRI/eCPRI base station units (BBU), optical transport equipment (OTN), and outdoor edge compute enclosures.

How to Select and Verify an SFP+ Cage Assembly Replacement

When evaluating or sourcing 2x8 stacked SFP+ 16-port cage assemblies with integrated connectors and lightpipes for new line card designs or supply chain diversification, hardware engineers should verify the following core parameters:

• Integrated 320-Pin Receptacle & Lightpipe Configuration: Confirm whether your PCB footprint and faceplate require an all-in-one integrated 2x8 cage with pre-installed 320-position connector and lightpipes versus discrete cages.
• Press-Fit Tail Length & Board Thickness: Ensure the 3.0mm press-fit tail length matches your motherboard specification (TE 2149490-5 is optimized for standard 1.5mm PCBs to terminate dual-tier 320-position signal pins).
• Port Matrix Configuration (2x8 16-Port): Confirm that a 2x8 stacked footprint (2 rows x 8 columns = 16 ports) aligns with your front-panel I/O port height envelope and bezel cutout matrix.
• EMI Shielding Mechanism (External Springs vs Elastomeric Gaskets): Confirm whether your chassis bezel cutout design is optimized for metallic spring fingers (providing low contact resistance across 16 ports) or conductive elastomeric gaskets.
• Mechanical Drawing Verification: Check 320-position press-fit hole patterns, lightpipe exit locations, and grounding spring tolerances against official engineering drawings.
