When choosing between QSFP and QSFP28 cages, it's important to understand the specific features and benefits each type offers.
These cages are designed to support their respective transceiver modules and play a critical role in maintaining signal integrity, thermal management, and overall performance.
| QSFP Cages: | QSFP28 Cages: | |
|---|---|---|
| Data Rate Compatibility | Designed to support QSFP modules which typically handle data rate up to 40 Gbps. | Engineered for QSFP28 modules, supporting significantly higher data rates up to 100 Gbps. This makes them suitable for high-bandwidth applications. |
| Physical Characteristics | Available in single, ganged, and stacked configurations with various customization options like lightpipes and heat sinks. They typically use a 38-position connector. | Similar in configuration options (single, ganged, and stacked) but are optimized for better performance with QSFP28 transceivers. They include enhanced features for improved heat dissipation and electromagnetic interference (EMI) shielding. |
| Thermal Management | Require adequate cooling solutions as QSFP modules can generate significant heat. Standard options include integrated heat sinks. | Offer advanced thermal management features, such as more efficient heat sinks and better airflow designs, to handle the higher power consumption and heat output of QSFP28 modules. |
| EMI Shielding | Provide basic EMI shielding to protect signal integrity, suitable for the typical operating conditions of QSFP modules. | Enhanced EMI shielding to support the higher frequency and data rates of QSFP28 modules, ensuring superior signal integrity even in dense and high-interference environments. |
