Available in various configurations, including QSFP28
Precision-engineered dimensions ensure exact fit with SFP28 modules.
SFP28 cages are essential enclosures designed to protect and optimize the performance of SFP28 modules within networking and telecommunications equipment. These components ensure secure connectivity and optimal functionality in data transmission applications.
The SFP28 (Small Form-factor Pluggable 28) is a high-performance optical module designed for 25 Gigabit Ethernet applications. It provides a cost-effective solution for high-speed data transfer in data centers, telecommunications networks, and enterprise environments. SFP28 modules support a single channel of 25 Gbps, making them an upgrade from SFP+ modules, which support up to 10 Gbps. These modules are known for their compact size, energy efficiency, and compatibility with various network equipment, enhanced network performance.
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.
