Whitepaper: Stacked 2xN Interconnects in South American Infrastructure

Brazil's Industrial Context & 5G Rollout

As Latin America's largest digital market, Brazil is driving unprecedented demand for cloud data centers and ultra-broadband communications. Telecom network operators in major hubs like São Paulo, Rio de Janeiro, and Curitiba are expanding their infrastructures with standalone 5G (5G SA) technologies. This digital transformation requires dense and space-saving hardware designs to handle massive network switching and routing capabilities.

2xN stacked port cages (such as 2x1, 2x4, 2x6, and 2x8 port layouts) provide the ideal balance between density and performance. By vertically stacking the transceivers on the PCB, local equipment manufacturers can double the high-speed I/O port density. This is crucial for local equipment manufacturers trying to align with ANATEL standards while maximizing throughput in their equipment designs.

Global Connectivity & Supply Chain Demands

Globally, the optical communication market is moving from 10G and 25G channels to 100G and 400G configurations. Transolix bridges the gap for local system integrators by supplying fully compatible SFP+ (10G), SFP28 (25G), and zQSFP+ (100G) stacked interconnect systems. These systems match international specs (TE Connectivity and Molex replacements) while offering localized logistic support.

By utilizing multi-point EMI spring fingers and robust press-fit structures, our connectors maintain signal integrity at extreme data rates, preventing high-frequency noise leakage in high-performance networking equipment.

Technical Roadmap & Future Outlook

High-frequency data pathways face challenges with insertion loss and heat dissipation. The technical roadmap of Transolix stacked cages implements advanced material science and innovative mechanical designs to overcome these issues:

  • Integrated Light Pipes: Custom-designed polycarbonate light pipes direct LED indicators from the PCB to the front bezel, keeping the visual panel functional even when stacked two ports high.
  • EMI Shielding Options: Elastomeric gaskets and metal spring fingers ensure effective shielding in compliance with FCC and CISPR regulations.
  • Press-fit (Elastic Pin) Technology: Solderless press-fit pins allow quick PCB installation and easy rework, reducing factory line failure rates for Brazilian electronics assembly lines.
  • Thermal Management: Engineered ventilation holes allow airflow between stacked ports, maintaining optimal temperatures for high-power optical modules (Class 1 to Class 4).

Frequently Asked Questions

Technical & Commercial insights for importing stacked port cages and custom fiber solutions into Brazil.

Are your 2xN stacked SFP+ cages fully compatible with TE and Molex footprints?
Yes, our stacked SFP+, SFP28, and zQSFP+ cages are designed as drop-in replacements for industry-standard connectors by TE Connectivity and Molex. They share identical footprints, pin assignments (e.g., 240P, 160P, 80P), and mounting structures, allowing seamless replacement on your existing PCBs without layout redesigns.
How do you handle importing and customs clearance (Mercosur / Receita Federal) to Brazil?
We have extensive experience shipping to Brazilian hubs, providing detailed commercial invoices, pack lists, and HS codes to streamline customs clearance at airports or maritime ports like Santos. We also assist with the documentation required for local ANATEL homologation if needed.
What testing procedures are applied to ensure high signal integrity at 25G and 100G?
We run comprehensive signal integrity tests, including eye diagram analysis, network insertion loss testing, and return loss sweeps up to 28 GHz. Our 2x6 and 2x2 zQSFP+ cages feature advanced EMI spring gaskets to maintain low noise floor levels, ensuring high reliability under strict operating conditions.
Can you customize light pipes and heat sinks for specific chassis heights?
Yes, we provide flexible customization for light pipe shapes, thermal heat sinks, and EMI fingers. Based on your chassis design and mechanical parameters, our engineering team can modify these subcomponents to ensure compatibility with your enclosure.
