Welcome to GLGNET, your trusted SFP cage & connector manufacturer.
Our high-quality Single and Multiport SFP cage & Connectors meet
industry standards and are perfect for Fibre Channel and Ethernet applications.
Selecting the appropriate SFP cage connector is crucial for ensuring optimal network performance and reliability. Here are some important factors to consider:
| Factor / Consideration | What to Check / Why It Matters | GLGNET Relevance |
|---|---|---|
| Data Rate Support | Verify the SFP cage & connector support the required data rate for your application. | GLGNET SFP cages & connectors support data rates up to 1 Gbps Ethernet for high-speed links. |
| EMI Shielding | Good EMI control helps maintain signal integrity in noisy environments. | GLGNET offers cages with EMI gaskets / springs to ensure stable, low-noise performance. |
| Mounting & Installation | Mounting type must match your PCB design and assembly process. | GLGNET provides press-fit and other mounting options for secure, easy installation. |
| Physical / Mechanical Design | Cage form factor (single-port / multiport) should align with mechanical and layout constraints. | GLGNET supports multiple port configurations to fit different PCB layouts and chassis designs. |
| Customization & Flexibility | Custom features can help match thermal, optical, or mechanical needs in your system. | GLGNET offers custom heat sinks, light pipes, and mechanical tweaks for tailored solutions. |
| Compatibility with SFP Modules | Cage should accept a wide range of SFP transceivers to keep the design flexible. | GLGNET SFP cages are designed to work with various SFP module types and connector styles. |
Understanding the differences between SFP, SFP+, SFP28, and QSFP is essential for choosing the right networking equipment. Each module type, along with its corresponding cage, offers unique features tailored to specific applications and performance requirements.
