SFP28-25G-BX-U-40KM-DL-BO BlueOptics BO04Q27640D Transceiver

High-Density 25GbE SFP28 BiDi Singlemode Transceiver for Long-Reach Links with the SFP28-25G-BX-U-40KM-DL-BO

The SFP28-25G-BX-U-40KM-DL-BO is a 25GbE SFP28 BiDi singlemode transceiver designed for single-fiber LC-Simplex deployments where rack-to-rack or site-to-site connectivity must scale without adding additional fiber pairs. By using a BX-U optical architecture, the SFP28-25G-BX-U-40KM-DL-BO supports efficient port density on leaf/spine switches and aggregation platforms, while maintaining deterministic link behavior for enterprise Ethernet fabrics.

Optimized for 25G ETH protocol operation, the SFP28-25G-BX-U-40KM-DL-BO targets ZR-class 40km nominal reach on SMF, enabling stable uplinks across metro, campus backbones, and data center interconnect routes. The 1270nm transmit/receive wavelength plan simplifies duplex constraints and reduces fiber utilization pressure in environments where optical plant expansion is costly. 

Why Choose the SFP28-25G-BX-U-40KM-DL-BO?

The SFP28-25G-BX-U-40KM-DL-BO provides an architecture-driven path to extend 25GbE over singlemode at long reach while preserving switch port density and minimizing fiber count. It is suited to scalable rollouts where operational consistency, predictable optical budgets, and clean LC-Simplex patching improve deployment repeatability across multi-site networks.

BlueOptics focuses on enterprise-grade optics engineering with validation aligned to modern data centre cabling standards, interoperability requirements, and lifecycle stability. This approach supports controlled change management for optical components in production Ethernet infrastructures.

Key Applications:
