25GE SFP28 2x4-A5 WITH OUTER LIGHT PIPE
25GE SFP28 2x4-A5 WITH OUTER LIGHT PIPE Description
39016-04XXX1 combines a 2x4 stacked SFP28 connector structure with 8 outer light pipes in a Left Down arrangement, making visual indication one of its strongest product-specific features. Instead of being a plain dense cage, it is built to keep port status readable across a stacked array where multiple 28Gbps interfaces share one front-panel area.
The press-fit structure and EMI finger add two more defining elements: solder-free board installation and shielding support around the opening.

Key Advantages of SFP28 Cage Connectivity
Built for 25G-class transmission, SFP28 cage delivers higher per-port bandwidth, better lane efficiency, and a compact interface format that fits modern data center and high-throughput equipment.
SFP28 Connector Applications in 25G Networks
SFP28 is commonly used where 25G single-lane performance is a better match than traditional 10G links, especially in platforms that need more bandwidth per port without sacrificing density.
25G server-to-switch interconnects
25gb SFP28 is widely used between servers and Top-of-Rack switches in data centers where 10G access links have become a limiting factor. It provides a more suitable bandwidth level for newer server NICs and higher east-west traffic loads.
100G breakout and leaf-spine switching architectures
In many switch designs, 100G uplinks are broken out into 4 x 25G lanes. SFP28 fits this architecture well by giving server-facing and edge-facing ports a lane speed that aligns more efficiently with 100G network fabrics.
High-performance storage and NVMe-based systems
SFP28 connector is also well suited for storage platforms and backend fabrics that move large data sets continuously. The higher single-port throughput helps support faster replication, lower congestion, and better performance in bandwidth-heavy storage environments.
AI, HPC, and cloud computing platforms
AI clusters, high-performance computing systems, and cloud infrastructure often generate heavier traffic patterns than traditional enterprise networks. 25gb SFP28 is a stronger fit for these environments because it supports denser 25G connectivity at the server and equipment edge.
